> "UNA is currently a non-submersible device due to its innovative modular design. So, swimming is not something we offer as an activity, nor do we advise it. UNA is IPX5 rated, which means it is splash & showerproof to a high degree."

If I had a dollar for every time some project that was ipx5 rated failed after getting caught in the rain one too many times...I'd have enough to buy another Garmin Fenix.

Comment by PunchyHamster 5 days ago

Yeah that's a non-starter, I don't ever wanna worry about that in a watch. And putting "designed for lifetime" next to it is just hilarious, where are you gonna trek with no water, from bathroom to kitchen ?

Comment by frankbreetz 5 days ago

the bathroom and kitchen both have faucets! You can potentially trek from the bedroom to the living room

Well our inmates have washbasins in their bedrooms and we have more inmates than some European countries have citizens.

Those are not exclusive statements — as long as parts are available for a lifetime

Comment by jerlam 5 days ago

There are zero spare parts available on their website.

If repairability is one of their selling points, not having spare parts immediately available is a big misstep.

Looks like display and battery are “coming soon”, and those are the only 2 parts they have repair videos for as well.

Comment by quickthrowman 5 days ago

I would not buy a watch rated less than IP68/IPX-8, annd ideally it would be much more water resistant. Apple Ultra watches are rated to 100m of water which is well beyond that.

The watch I am wearing right now is a steel automatic that would have an IP69 rating as it’s rated to 150 meters of water depth.

Comment by peterleiser 5 days ago

The only IP ratings that I trust are on dive computers and dive computer watches (but I've read mixed results about Apple Watch Ultras for diving). The Garmin Descent Mk3i dive computer and smart watch is a solid performer.

Comment by whynotmaybe 5 days ago

Cue to younger me that discovered the difference between water resistant and water proof when I found out that my "7 melodies electronic watch" didn't survive after a few minutes in the swimming pool.

Will the UNA hint us with a little bit of fog on the window?

Comment by aa-jv 5 days ago

I too destroyed my "7 melodies electronic watch" back in the 80's by taking it for a swim at the beach .. man, that was so disappointing. Did get me on the CASIO Data Bank train, though ..

Comment by amelius 5 days ago

If you ever get into this situation again, you can rinse it with distilled water to remove corrosive/conducting residues, then let it dry.

Or middle-aged me swimming with my "10 ATM water resist" ~$400 Hamilton watch...

Comment by jubilanti 5 days ago

I got all the way to the order screen thinking it was IP68 because my eyes scanned over "UNA features a universal IP68 rated usb-c charging cable" and thought the port was IP68.

The CABLE is IP68? But the watch is IPX5? This is just up to the line of criminally deceptive false advertising. It's not criminal because the fine print, but what an absolute loss of trust. They know what they're doing. IPX5 is a no-go, which they know, which is why they're being so deceptive.

Comment by wincy 5 days ago

My first (and the original) Apple Watch, I won at the company Christmas party. My kid dropped it in the tree sap water under the Christmas tree and I didn’t find it for two days. After a lot of cleaning, it worked perfectly fine for years. I’m on the series 10 now. They’re very tough little devices.

Comment by TylerE 5 days ago

1st gen is 1P7X, and 2nd gen and later are certified to depths of at least 50m.

Way beyond IP5X.

Comment by microtonal 5 days ago

Same for most Garmins (Fenix 8 even has inductive buttons to avoid worn-down seals), Coros, and recent Galaxy Watches (the way beyond IP5X part).

Note though that all these watches are water resistant, the seals degrade over time and water can get in. Even the Apple Watch Ultra, plenty of people who had it leaking after scuba dives or even after swimming.

You can usually improve longetivity by following manufacturer instructions (e.g. typically rinsing with tap water after pool or sea use, avoiding saunas/steam baths, etc.).

Got an SE 2 a year ago to track my daily swimming in the sea and it's been working great.

Comment by tomaskafka 4 days ago

Not at all. 2.5 year old Apple Watch, glue gave up after warm pool in aquapark (40 deg Celsius), water got in, dead.

Comment by black3r 5 days ago

my first apple watch (6th gen) died when I was using it on a water slide ending in a pool on a holiday... since then I'm wary of using it in water...

Comment by peterleiser 5 days ago

Yeah, and drop your iPhone, in a ruggedized case, into 3 inches of bath water for 5 seconds from a height of one foot and then realize apple's IP68 claim is laughable.

Comment by ruszki 5 days ago

I wash my iPhone like every month. As I do with all of my phones for the past decade. Zero issues. I had a problem only once a long time ago, when I was in water with one of my Sony, but they replaced it immediately. No issue with the replacement.

Comment by black3r 5 days ago

washing is okay but dropping it in a pool destroyed my charging port on iPhone 14... the phone kept working and was rechargeable wirelessly though...

Comment by microtonal 5 days ago

Yes, this happens to people all the time. The seals that keep water out degrade over time. New phones are generally ok, but heat, dirt, detergent/salt in water, etc. wear them down until they are not water resistant anymore.

This is also why almost none of the manufacturers will fix the device under warranty when there is water damage, despite the IP rating.

Even Apple themselvers recommend against submerging and iPhone in water:

To prevent liquid damage, avoid: [...] Intentionally submerging your iPhone in water

https://support.apple.com/en-us/108039

The water resistance in these phones exist so that the phone hopefully survives when they get wet accidentally (heavy rain, pool drop, etc.). Not to shower with the phone, cleaning it by putting it under the tap, or doing underwater photography. Usually, it survives, until the seals fail.

Comment by alt227 5 days ago

> The water resistance in these phones exist so that the phone hopefully survives when they get wet accidentally

So accidentally dropping the phone in a bath or toilet for a few seconds doesnt count as that?

Comment by RobotToaster 5 days ago

Most water rated devices will warn against wearing them in the shower/bath because surfactants (soaps) let water penetrate a lot easier.

Comment by Melatonic 5 days ago

I thought it was that the jets of water (sprayer) increase pressure and are actually harsher in some ways vs submerging ?

And of course high heat melts the glue (like hot tubs)

Comment by LaGrange 5 days ago

It’s more than one thing but the surfactants are pretty bad.

Comment by Melatonic 4 days ago

Interesting. I've seen people wash their phones in just simple soap and I've done the same many times. I only use pretty minimalist castille soap though. Figured that would have the least chance of damaging the oleophobic coatings

My old iPhone 13 I used to take swimming daily in a salt pool, it was still running fine after 2 years of that, although the contacts in the lightning port did eventually corrode (now I can only charge it wirelessly)

Dropped my iPhone in the toilet , never skipped a beat after that.

Comment by speedgoose 5 days ago

I felt while running next to the sea and my iPhone bounced on the ground and ended up somewhere in a levee under water. We could call it until the battery ran out of power. So I guess it depends.

Comment by peterleiser 5 days ago

Exactly, it depends. I completely believe your experience. My wife's experience was instant bricking and Apple's warranty completely excludes liquid damage. If you have Apple Care+ they'll replace it for a fee.

Comment by mplewis 5 days ago

What? I have never had an issue with this with my iPhone.

Comment by fguerraz 5 days ago

I mean, they're from Scotland, the watch would have to be pretty water resistant to survive more than one day...

Comment by RobotToaster 5 days ago

The fact that they call it an "open source wearable" when only the SDK is open source feels underhanded. You'd expect at least the OS to be open source.

Comment by prmoustache 5 days ago

Well, to be honest, the OS might be ooen source but it doesn't have to be publicly available to everyone.

The only way to find out is to find someone who bought it and asked for the source code of the OS/firmware and the schematics.

Comment by luckystarr 5 days ago

OS is listed as FreeRTOS.

Comment by aa-jv 5 days ago

.. so thats freely available, but the question is whether UNA are making that source available too .. would be fantastic if they did!

Comment by lobster2342 5 days ago

I just finished swimming, tracked by a Garmin Forerunner 910x which I bought back in 2015 and I have been constantly using since. Wrist band replaced once each side. Battery lifetime still amazing, even with longer bike rides and GPS. Data can be analyzed locally. Uptime since I bought it: almost 100%.

Amazing peace of Hardware.

Also their algorithms are cool. If the watch tells me to rest more than 24 hours, I know, I will be tired the next day.

The two features that I miss are built in heartrate monitor and temperature sensor. I payed around 500€ back then. Over the years I use this watch, the price became very reasonable.

Comment by sandworm101 5 days ago

As a former very very fast swimmer, i never found a watch that worked. The ones with the features were to heavy/draggy. So i always bought dirt cheap ones that i could leave at one end of the lane. Cheap ironmans. They got stepped on every day. People would apologise and i would throw the watch across the deck to show how much i did not care about scratches. Try this: put your watch on your other wrist. The weight/drag difference will be dramatic.

Comment by Melatonic 5 days ago

Couldn't you clip it to the little lane dividers or hang it from the edge somehow ?

Comment by NBJack 5 days ago

Honestly, Garmin watches are amazing. Going from a watch I had to charge daily (Samsung Gear line) to one I charge about 3 times a month feels incredibly liberating, particularly for travel. _And_ it feels almost as slim and light as my old Pebble Time Round.

Comment by peterleiser 5 days ago

I agree completely! Our Garmin Descent Mk3i dive computer smart watches are the best watches I've ever seen. They just work. You can charge it for an hour or so and it's good for 25 days. I hated having to charge previous watches every day. It has a double-tap light on/off feature with a very bright LED, four light levels, and a red light mode. It automatically starts tracking my dives and is rated to 200 meters. It can also do diver-to-diver messaging, air tank tracking, and group tracking using subwave sonar. And it has all the normal pulse ox, heart rate tracking, step tracking, sleep tracking, and smartwatch stuff. Just don't enable the one touch kill-switch ;-). Apparently it's a feature for military divers to erase their data (but sounds like a marketing gimmick).

Comment by cyberax 5 days ago

Pebble Time 2 is available again! I bought one.

It doesn't have all the Garmin features, but it's free and I don't have to worry about it's software getting redesigned.

Comment by microtonal 5 days ago

True, but in defense or Garmins, one cool feature is that they are really similar to their GPSr units in that you can just connect them to a computer and transfer data and maps (including many custom maps) through MTP (or as a USB drive on older models). Plus they work with Gadgetbridge. So you can pretty much use the watch forever without Garmin involved.

Comment by cyberax 5 days ago

Yep, agreed. Garmins are great! I tried Fenix and I liked its feature set, but it's just too large for me physically.

Comment by microtonal 5 days ago

If only the map rendering wasn't so terribly slow. I often use mapping when cycling and panning or zooming the map is just unbearably slow.

I'm now usually taking the Coros Nomad because it has super-fast maps and still a battery life of three weeks.

They are really great otherwise and I love my Coros Nomad and Garmin Fenix so much more than the Apple Watch Ultra.

Comment by _giorgio_ 5 days ago

The missing heart-rate monitor is a pretty big limitation for a lot of users. LOL. Imagine writing a review and leaving the heart rate in last place. Just don’t write a review then.

Comment by dspillett 5 days ago

He's talking about an 11 year old device of a 15 year old (long since discontinued) design, even flagship devices were less featureful then than some mid-market devices are now. Imagine expecting a review of such a device to be enticing to someone comparing modern options…

Also, not everyone with a GPS watch cares that much about heart rate. I am a runner (well, less so now that I used to be, but working on fixing that) and have a Feninx7, not for the health tracking features but for route tracking and the long battery life (for “ultra” events covering many hours or even multiple days).

That's just an old and not useful device.

Comment by roryirvine 5 days ago

GP is talking about a model that was released 14 years ago, and is closely based on one from 2009.

Seems to me that "still working well after more than a decade of use" is a more useful piece of info than "newer models include additional features".

Is a stone working after 1000 years? Yep, still a stone though.

Comment by kitd 5 days ago

I have a Garmin Vivoactive 3. Fantastic watch but I find the HRM underwhelming. Not very accurate and drains battery. I pair a chest band with it instead for much better quality monitoring.

Comment by the_real_cher 5 days ago

i have a fenix solar, i charge it once a month.

it has an insane number of features

Comment by microtonal 5 days ago

The price is also insane nowadays though. IMO they are very vulnerable to the likes of Coros, who also have MIP watches that last for weeks, have much faster mapping and are less than half the price.

Comment by the_real_cher 4 days ago

I know. I got a health perk at work for the year and used it all on the watch. I don't know if it would have been worth it to me without that.

How's the accuracy on the Coros watches?

Comment by microtonal 3 days ago

I haven't compared it with a heart rate band yet. GPS accuracy is good since I enabled dual-frequency (MAX), before I had some inaccuracy in (urban) canyons.

Comment by DANmode 5 days ago

Are these algos local, as well?

Comment by theshrike79 5 days ago

Yes, mostly because the Garmin app on iOS is pretty bad at keeping a live connection up even for weather =)

Comment by lrae 5 days ago

Some good points were already brought up in the comments (IP5X, USB C charging), but I have the feeling that it's also just not a good fitness tracker/smartwatch.

I see a single unboxing of the watch from three weeks ago on Youtube and zero reviews on YT or websites. Just posts based on their PR release that it's available now. (Though some clearly already shipped.)

Thus, it's unfortunately very likely that the product is also not good at its main purpose, tracking activities, workouts and health. If it would only even come somewhat close to the performance of all the competitor smartwatches/trackers, they'd be louder about that part.

Comment by LeifCarrotson 5 days ago

There are only about 400 units in existence, and they just started shipping June 30:

https://www.kickstarter.com/projects/unawatch/meet-una-the-m...

so it's been out for less than a month. That's why you've seen zero reviews on websites, it's an indie Kickstarter. They don't have the marketing budget of a big wearables brand.

It has a GPS, IMU, and heart rate sensor: That's enough, obviously, to track activities, workouts, and health which their competitors do with the exact same set of sensors. It remains to be seen how accurate those are, or how well the manufacturer and community can develop useful algorithms to turn raw sensor data into activity logs and actionable health insights, but step 1 is to release an MVP to get people wearing the watch and logging data, and step 2 is to use the data to improve the algorithms.

Comment by microtonal 5 days ago

It's not as simple as just dropping a heart rate sensor though. It also took Garmin, Coros, Apple, etc. several generations to make good-enough heart rate sensors and most of them are very proprietary.

Comment by abstract_put 4 days ago

Not that it changes any of the rest of your comment, but from their Kickstarter campaign updates it seems like there are at least ~800 watches out there (and the public store just launched).

Comment by abstract_put 4 days ago

I ordered the watch and just had it show up this week. The software side of it seems pretty immature (as you'd expect from first launch), but there's visible progress from the tiny team already. Appeals to me to be able to write my own activities and utilities, though I'm mindful of how far their "openness" extends. Nothing is locked down on the watch so you can dump the firmware, but they don't make the firmware publicly available AFAICT.

The hardware seems top quality (looking past the waterproofing concerns, don't love that). On first blush it seems like its in the same league as my Garmin Fenix 6 Pro for tracking though, with obviously way fewer features at this point. I intend to do a side-by-side with the Fenix 6 and a heart rate strap to compare HR and GPS to see how it shakes out under tree cover and bouncing around, but the hardware seems up for it.

Comment by VoidWhisperer 5 days ago

Part of the selling point of a smartwatch, atleast in my opinion, is its ability to run apps that aren't developed by the manufacturer - for example, ones that help me be able to see my blood sugar from my CGM on my watch. They have a whole section of their site for developers, but I can't seem to find a link to any kind of store, even though they specifically say developers should register on their portal

Comment by arnejenssen 5 days ago

For me the value of Garmin (Forerunner) is their proprietary algorithm for calculating Stress Level from HRV. It is the basis for the Body Battery measure. I find it useful to see how food and activity affects my stress levels.

I guess it would be possible to reverse engineer a similar stress level calculation. Perhaps AI-powered?

Comment by scheme271 5 days ago

I'm not sure the body battery/stress measures are that great. Garmin is infamous for having an awful sleep algo and it still has a lot of trouble detecting naps. It doesn't bode well for being able to get stress data. I think it's good for generally determining high stress vs low stress and when you've overdone exercise recently but probably not much more.

Comment by rolisz 5 days ago

Body battery is amazing. I had long COVID/ME/CFS, and looking at the body battery when waking up was an outstanding predictor of how my day was going to be. When I hit 5% body battery, I was really feeling horrible.

Comment by throwaway270925 5 days ago

Interesting. What did you have to do to "charge" the body battery tough? And how does the garmin keep track of that?

Comment by mikestew 5 days ago

Naps and rest “charge”, and yes, Garmin keeps track of that.

Not that I put a whole lot of weight in those data personally.

Comment by catigula 5 days ago

It's just a collation of sleep-end RHR/HRV. It's completely trivial and many manufacturers do this correctly; both are extremely reliable predictors of recovery metrics.

Garmin has absolutely shitty sleep tracking but it doesn't matter; any wearable more or less nowadays can get static heart rate correct, leading to more or less accurate recovery metrics.

"Collect every paper you can find on RHR/HRV/etc. recovery metrics. Develop an algorithm for predicting recovery score per day based on the research" as a prompt to a Codex or Claude agent can probably get you 98-100% of the way there.

Edit: As a proof of concept, I had ChatGPT Pro 5.6 write the algorithm with my Fitbit data. Looks great.

Comment by patrickk 5 days ago

Do you have a particular hardware sensor requirement needed to clone the body battery function? I’m interested in developing this too but always resisted getting a smartwatch due to privacy concerns. If there’s something available that’s Gadgetbridge compatible I’d be very interested.

Good news; I'm gifting you with the fruits of AI, that has collated 200+ papers on the topic. I know, I know; this is generous.

Comment by patrickk 4 days ago

Incredible thank you!

I’ve had Claude work on a body battery type solution, which I’ll fully deploy over the coming days. It’s to manage and track brain fog/long COVID type symptoms and see if there’s correlation between foods eaten the day prior, resting heart rate etc and perceived brain fog. I’ll see if it’s possible to incorporate some of your work into my solution too.

It took GPT-5.6-Sol Pro about an hour of work; don't thank me :P

Comment by Melatonic 5 days ago

How does HRV predict stuff like this ?

Comment by scheme271 4 days ago

HRV is an indicator of how much stress you are experiencing. The variability increases when you are more relaxed and under less stress and decreases as your stress level increases. The relationship is a bit counterintuitive but it's a thing.

Comment by TekMol 5 days ago

If the algorithm is proprietary, how do you know it is calculating something meaningful?

Comment by LeifCarrotson 5 days ago

It matches my lived experience.

My body battery and stress often starts declining for no apparent reason and then 12-24 hours later I feel the symptoms of an illness. Similarly, when in a tough training block, HRV is a great tool to gauge how hard I ought to be able to go: I've tried to push through and just do a tough workout anyways when it's out of range, but failed to complete the workout in good form, or felt superficially crappy but had good training readiness according to the watch and was able to do better than expected.

The same holds true in the other direction, I don't log into Connect or scroll through the multitudinous widgets of data often enough to really keep tabs on this stuff, and when I get sick or feel good or bomb a workout or succeed at a workout when I felt off, the metrics consistently back up the actual results.

Personally, I've been thinking about jumping ship to a Coros Apex 4 if my battered Fenix 6 ever gives up the ghost - Garmin's prices are insane these days. At $270, this is cheap enough in comparison to a $1200 Fenix 8 Pro to take the chance. I could buy this and a $480 Apex 4, and then decide I didn't like either of them and go back to a used Forerunner 955, before spending as much as a new top-end Garmin.

Comment by Melatonic 5 days ago

Personally using a 955 I recently (ish) got new direct from Garmin while they were still selling them. Got some major discount through a link I believe was tied to health insurance or something.

The newest watches seem insanely priced though and don't seem to add much. But the newest Enduro with decent solar is tempting

My Garmin Epix's Body Battery levels might as well be randomly generated. They don't correlate at all to how I feel. YMMV.

Comment by mtmail 5 days ago

Is that calculated locally or send to the cloud? I got fed up how many Garmin features required an account.

Comment by kilroy123 5 days ago

Yes, and the sleep tracking that adds or subtracts. While not super accurate, it's good enough for me.

Comment by Melatonic 5 days ago

I like this a lot. USB-C is obviously not ideal for a super durable plug but with the right cap (sounds like they use a rubber insert?) it could be great. Especially since it would allow direct data access.

What might be cool for a version 2:

1. Custom hardshell "door" to cover the USB-C port. Something that cannot fall off the watch. The port itself could be well sealed like a phone and then have this additional layer of physical protection.

2. Wireless charging of some type (or even add pogo pin as well). Would be nice to top up charge without having to expose the USB-C and probably increase the plug life. Does this require a glass back? Because obviously that would not be ideal in a watch.

3. Better waterproofing. I dont personally use my Garmin for swimming often but would be nice to not have to worry about it.

Anybody know about the battery life in real world use?

Comment by hackingonempty 5 days ago

This is cool because we need more open competition for the app/identity locked ecosystems of sports related electronics like gps watches, bike computers, and action cams. I hate how none of the major brand ones will work without at least signing up for an account and most wont work at all without the manufacturers app.

Comment by abeyer 5 days ago

Doesn't this also use its own app and services? The only "open" part of it I saw in the docs was that there's an sdk to write your own app that runs on the watch. Better than nothing, i guess, but not quite what I was hoping for.

Comment by hackingonempty 4 days ago

Sadly I think you're right.

Comment by znpy 5 days ago

Nice, this might be the right thread to ask a question i have had on my mind for a while: is there a watch that can track some biological metrics (heart rate, steps, sleep data etc) but allowing my to pull data off it without using some proprietary platform? Basically i want to store my data in my own database.

Might this be it?

Comment by Melatonic 5 days ago

I believe you can do this with most Garmins ?

Comment by codethief 5 days ago

Seconding this request!

Comment by kittikitti 5 days ago

This product category is very important to me because of security concerns. The push notifications are stored in a database on most smartwatches that are relatively simple to hack. This and other vulnerabilities represent a significant attack surface on top of smartphones.

On a more social side, I find that people are more frustrated if I don't immediately reply when they know I have a smartwatch. While I understand that these watches make it easier to stay notified, I find it annoying to have more expectations in return. I still have plausible deniability with smartwatches similar to the Una watch. Otherwise, the toxicity of the technology is significantly greater.

Comment by jhoechtl 5 days ago

Is there any good watch outside doing GPS for position and time, minus all the body survzeilance things?

Comment by m463 5 days ago

I have garmin as it doesn't require any sort of connection or activation to function out-of-the-box.

Just put it on your wrist.

You CAN decide to use garmin-connect for apps/updates or pair it with your phone, but I never have and I'm fine.

Apple watch and others require activation.

Comment by jerlam 5 days ago

You can plug in a Garmin to a computer with a cable and pull the files off the watch, as it acts like a USB drive. No app required.

It does require MTP which I had trouble with on linux. maybe it's better now.

Comment by pimlottc 5 days ago

They hardly even mention the software, but isn't that half the value of Garmin devices?

Comment by belval 5 days ago

More than half imo, my Forerunner 265S is pretty much a full-blown coach that fits on my wrist. It adapts training to my sleep (such a great feature when you've just had a baby) keeps track of load, low aerobic, high aerobic, etc...

It's been a fragile piece of hardware, I am on my 3rd one in as many years (always replaced under warranty though), but I still probably wouldn't switch to anything else. When it breaks out of warranty I'll just buy another one.

Comment by exabrial 5 days ago

If it has a flashlight and is beyond waterproof, I would maybe consider it.

My Garmin Epix watch is practically bullet proof. I've dove with it in open ocean. I've jet skied with it. I rock climb with it. It's surived 108miles of Unbound (the race) in mud, sun, sweat. I've water rafted with it. I've swam in crappy lakes, streams and jumped off cliffs. Hottubs? also no problem.

Zero chance a iWatch would ever survive these conditions.

Oh and despite all of this, the screen has not scratched, not even a little. Plus it has 5-10 days of battery life... and did I mention I always have a flashlight on me?

Comment by mikestew 5 days ago

Mine survives such things just fine.

My Garmin Epix watch is practically bullet proof.

And your Epix cost about twice as much as the Una watch does.

Comment by exabrial 5 days ago

Epix Gen3 is $500 w/ Garmin Discount. iWatch ultra is $800.

And iWatch doesn't have a flashlight. And iWatch doesn't have the same battery life.

Comment by mikestew 4 days ago

We were talking about the Una watch, and you were, too. Your Epix still twice the price, so the comparison is invalid.

As for the "iWatch"<sic>, well, if you haven't researched enough to get the product names right, maybe it's best we move on with our day.

Comment by lrae 5 days ago

Same. Both have plenty of scratches here.

I also don't see why an Apple Watch wouldn't survive all those mentioned things. Pretty sure I did all those things with an Apple Watch on, except for the specific 108 mile gravel race. But I don't see why it would fail that.

And both might absolutely scratch while climbing, and if you're unlucky and hit it in the wrong spot, also crack.

That said, if I were an athlete in any of those categories and did it all the time, I'd still absolutely choose a Garmin.

>And both might absolutely scratch while climbing,

Negative, just the iWatch. I'm scratch free despite outdoor climbing on limestone, sandstone, and granite.

I do take it off for crack climbing since it's a safety hazard.

the sapphire screens are incredibly resilient. mine looks brand new and is several years old. tested against plenty of bouldering

Comment by lrae 5 days ago

They are, they still scratch though (just google e.g. Fenix 7 Sapphire scratches). It's also not on all models. I guess part of it is also just layers on top of it scratching and not the sapphire itself.

But, Apple Watch Ultras and also Titanium models since Series 6? ship with Sapphire crystal too.

Comment by notesinthefield 5 days ago

Until I got to the Forerunner 965, my Garmins would easily scratch. I have an Instinct with such a deep gash I cannot see the top 1/4 of the display. The 965 display is wonderful but I still have a couple minor nicks.

i have one too with a sapphire screen (fenix 7). the watch is beaten up but the screen looks brand new. really phenomenal watches.

Comment by iancarroll 5 days ago

I've wasted so much money on vendor charging cables in the past 10 years while traveling or moving that I would probably buy this just for the USB-C port, assuming it is actually splash proof.

I wonder what HR sensor they use. Samsung apparently has an average error of 7% which is pretty bad, so I wonder if this would be worse. [0]

Love the idea, but I can't handle the big screens on these smart watches. To me it feels like having a fisher price toy on my wrist. Hopefully a more open alternative to Withings will emerge

Agreed. And beyond the size, MIP > OLED all day long for me. I'm sad to see it falling out of favor on flagship devices.

Comment by LeifCarrotson 5 days ago

This is a comparatively small one: 40.25mm diameter screen, 14.4mm thick, at 50g.

My Fenix 6 Pro has a 47mm face, is 14.7mm thick, and weighs 80g (but as a Fenix that's the stainless bezel one, the plastic bezel watches are closer to 50g).

I thought the same thing. Then gradually got slightly larger watches when I upgraded fenix 6 -> 7 -> 8. (also lcd->lcd->amoled) Now I don't notice.

Comment by mikestew 6 days ago

I really want to like this watch. Price is certainly right, and it does all of the things I'd want out of a Garmin or Apple Watch Ultra. But what problem does this solve for me? In the Apple Watch use case, a replaceable battery would be nice. But in contrast to Garmin, I've never replaced a Garmin because the battery wouldn't hold charge anymore. I've never broken a screen (if one has a habit of that, Garmin and Apple make watches with raised bezels). I just hold on to the Garmin for six or seven years, by which time it's so beat to hell that it's time for a new watch anyway. But I'm wondering if the subtle message isn't aimed at Apple and not Garmin.

USB-C charging would be awesome, instead of Garmin's proprietary plug and a cable that's made from spider silk. I'd prefer, though, wireless charging like Apple. Never once have I pulled an Apple Watch off a charger and said, "WTF? Why didn't it charge?" Garmin, OTOH...

I'm no triathlete, but the "no swimming" kinda puts a damper on my enthusiasm as well.

I wish them well, I love the idea even if I probably won't buy one.

Comment by throwway120385 6 days ago

USB-C would suck. Part of the purpose of that proprietary plug is that it's very water resistant and very durable. Imagine getting mud or coarse sand in your USB plug and not being able to charge anymore.

Comment by weakfish 5 days ago

For me, I want an open API I can pull my data from. Last I checked, you have to be a business to use Garmin's API.

Apple certainly doesn't let you.

My goal is to have a cron that runs on my homelab that pulls my health data into a DB I own, from various sources, and visualize it in Grafana.

Comment by mikestew 5 days ago

Apple certainly doesn't let you.

There are several apps[0] off the top of my head that pull data from Apple's HealthKit. Apple even has a framework for it: HealthKit. That said, I've never written to that API myself, but it observational evidence indicates that you can pull data from Apple just fine. The app I use to pull data off Apple and ship to Strava says as much.

[0] RunGap and HealthFit

Comment by weakfish 4 days ago

Oh yeah, I should've clarified, I mean via a REST API. I thought about building an app for myself to do what I wanted to do, but it's frustrating that I can't just set up a Cron on my homelab to pull my data.

Unless I'm missing something and HealthKit does provide this.

Comment by mikestew 3 days ago

RunGap will export a FIT file (w/o looking, I think it’s FIT) to iCloud and Dropbox. So it’s technically possible to glue some pieces together. Practically? Dunno, but it might worth a look at RunGap’s web page to see where they’ll export, maybe something will work for you.

Too bad Garmin turned into buttholes about their API. It used to be a lot easier to deal with.

you can use https://github.com/cyberjunky/python-garminconnect to pull your data from garmin, I've been using it daily with no issues

Comment by enbarca 5 days ago

I ran into the same issue when building ProForta.com. My solution was to build a companion app that pulls data (including Garmin) via Health Connect. Right now, it seems that every hardware platform from Oura to Garmin is trying to build their moat around user's data. That's not OK - users need access to the combination of all their data to derive meaningful health benefits. Thats the guiding principle behind lifecare.id (https://lifecare.id)

Polar has an API where you can get more or less anything out. That bit is fine - sadly you can't put things in (like virtual cycling, or any activities not recorded on the Polar).

Depending on what data you want, you can try Withings watches. I'm currently reversing the protocol and it mostly works.

The charging situation with Garmin is terrible, enough that when Venu quits charging I might go for the Apple Watch or anything that takes a charge...

Comment by mikestew 5 days ago

And it's always been terrible, as long as I've been using Garmin watches (their bike computers seem to charge fine, mainly because they use whatever the standard USB plug is at the time). I remember the 410 had some suckass plug that didn't work well. I think it was the 610 with that gawd awful clip. And the 9xx series continues to use that delicate snowflake plug that has to plug in juuuuust right, maybe wiggle the cable a little, otherwise no 5 hour Sunday run for you.

Whereas I throw my Apple Watch in the general vicinity of the magnetic charger, it locks into place, and charges just fine, 100% of the time. Fine, don't use induction like Apple, use two exposed, flush pins and a magnet like my Coros armband HR monitor, because that works 100% of the time, too.

Comment by tamimio 5 days ago

The problem isn’t “one screw to change a battery”, the issue is parts cost, if they are expensive, it defeats the purpose. The other day I wanted to buy a new small container for the air freshener I have, and I found the container only is sold in packs and far more expensive than buying the freshener with one container, so I bought a new device instead with one container.

Also, any watch right now should be waterproof, it won’t survive otherwise.

Comment by ajnin 5 days ago

Not to pile up on the negativity, but looking at the SDK, first reaction is it's fucking C++ ? Can't wait for my watch to crash in the middle of something. And second reaction, when I see signatures like this :

  void TrackFaceTotal::setDistance(float dist, bool isImperial);
  void TrackFaceOverview::setPace(float pace);
and

  bool     unitsImperial;
littered everywhere, it makes my heart sink a little. Can't we have some data types and data modeling in 2026 please ? And leave unit conversion at the front end where it should be and not have to worry about it in every single core API ?

Comment by LeifCarrotson 5 days ago

No, we can't. It's an ultra-low-power embedded ARM Cortex-M33 (successor to Cortex-M4) processor, the right language to use when programming it is C++. You want a minimum of abstractions and a close-to-the-metal programming environment to maximize battery life.

Be grateful it's C++, it could be raw C.

Comment by abstract_put 3 days ago

The TrackFace stuff is in example apps (consumers of the SDK), so AFAICT it's doing what you want: unit conversion in the front end.

That said, while I think you picked an example that undermines your point, the point does still stand. The SDK has a lot of rough edges (just not this specific one).

Comment by aa-jv 5 days ago

Just because its C++ doesn't mean it'll crash, come on, that's just lazy thinking. It could just as well mean that it will be rock solid and industrial strength. After all, a heck of a lot of very important life-critical systems run on C++ ..

Any "open ecosystem" product needs to be a competitive product out of the box, otherwise it's just a development toy. Developers aren't going to enhance your product to fill in all the gaps unless there are customers, and preferably paying ones.

Acknowledging I'm in a small niche, programmable high quality GPS watches are kind of not really a thing. As a developer, I find the hardware offering compelling and is something I jumped on. Agreed that it won't reach mass market with that mentality though.

I have an Amazfit Balance, and previously several Amazfit Bips. I really like being able to use my watch as a BLE heartrate monitor with iSmoothRun on iPhone. I gather that being able to do so is not typical for smartwatches.

Comment by SketchySeaBeast 6 days ago

I do like the idea of USB-C, the garmin's power plug is nothing but annoying. It's really just a matter of battery life and what sort of software integration it has. Although, it's hard to beat the Garmin ecosystem.

Comment by briffle 6 days ago

I think battery life is the most important. My Garmin Instinct 2 goes about 3.5 weeks between charging (the older non-OLED screen). It has solar, so I usually go over a month.

But a watch, something people will wear swimming, sweaty, in the rain, etc, is something that should ideally follow the wireless charging standards, and not have a plug taking up space, and being a spot for leaks...

Wireless would be ideal, assuming there's still some way to connect to my PC.

Round watches are bad. A circle is the worst shape for watches. Good watches are not round. Roundness is an anti-feature.

Really. Just use a rounded rectangle shape. It will end up _smaller_.

I doubt that modern smart phones are waterproof. Who would trust use their smartphone while showering or being in a bathtube (including submerging the smartphone a few centimeters into the water)?

Comment by vel0city 5 days ago

Tons of people trust having their phones while taking a bath or near a swimming pool. I've sometimes clean my phones off by washing them in the sink when they get exceptionally dirty after the kids have been messing with it. I regularly have mine near the pool, and have taken some work meetings while in the pool before. Why not? The featurelist says its waterproof.

I remember when the iPhone 7 had just come out (the first waterproof iPhone), a friend bought one and then went on a cruise. On a shore excursion he was at the docks and saw some cool fish. He dunked his phone in the water to take some cool photos. Everyone looked at him like he was a mad man, dunking his iPhone in the water just to take some pictures.

The title is misleading at least, to compete with garmin you need the similar offering, with swimming/waterproofing being the huge outliar here but also the ecosystem and like it or not features like the notifications.

Very valiant first effort for sure but after 6 years with a Garmin Fenix still holding 90% of its battery (and being able to replace it), I'm not their potential customer.

What kind of battery life did you have when you bought it, and how long is it now?

Does Garmin still upgrade the firmware?

Garmin doesn't really upgrade the firmware after the next model release.

But you'd be a fool to believe a hardware startup would do so anyway.

Talking about a 6s pro and got at the beginning around 10 days without much GPS enabled exercise, after 6 years I get about 9 days!

Good thing with the Fenix line is that you stop the updates which I did a year in so I don't really care about them, but I do think they stopped firmware updates for the 6series about a year ago.

Comment by tomhow 5 days ago

Charging? It likely adds a lot of cost and complexity to add mag-charging if you’re not Apple or Samsung. Does Garmin even have it yet? (Edit: only on a small number of models at the premium end of their range.)

So it’s an important differentiator from Garmin, which uses a proprietary connector for its charging cable, that is easy to lose/break and expensive to replace (from personal experience with a 2022 Epix).

Comment by LeifCarrotson 5 days ago

I love the Garmin pogo chargers. I've got a few of their $3 puck cables scattered about my home, car, and office, a USB-C to Garmin adapter in my keychain and backpacking kit, and someone recently made a neat little portable battery that I wore under my strap in an ultra to recharge mid-activity.

Yeah, if you only use the stock Garmin cable (why isn't it at least right-angle?!) it kinda sucks, but there are lots of products that do it really well:

https://www.amazon.com/dp/B0F5L632HM

https://www.amazon.com/dp/B0D4F71WQC

https://www.amazon.com/dp/B07N18DX6Y

I would much rather these totally waterproof surface-level pads that put the spring pogo pins in the cable than give up internal device volume to a USB receptacle or magnetic charging coils.
