Garmin 735XT

I've got the Garmin Forerunner 735XT and while the software is a little clunky at times, it's a total work horse. Battery lasts for a week when worn all day and with at least 30 minutes of GPS tracked running activity per day, the display is extremely well to read outside in the sun and the smart features I use are the app notifications and that's it. No complaints, that thing is indestructible and I would buy it again. The prices at times are truly comical though, then again I've got this watch since 2017 and it's still going strong, I'm sure I would have gone through at least a couple of Apple Watches or Android Wear watches in the meantime.

I second this. If battery life and fitness features are of the upmost importance, check out a Garmin, Polar, Suunto, or something similar. They can last for many days on a single charge using GPS regularly and the only charging I do is when I'm showering, meaning I can track my sleep. I've had a Garmin 735XT for three years and it's not showing signs of age. It's less of a smartwatch and more of a fitness tracker, since the extent of "smart" features these watches often possess is limited to receiving notifications and possibly playing music, but I don't use these features anyway. I used an Apple Watch in the past, but much prefer a simpler fitness tracker. The only thing I miss is the ability to listen to podcasts using only a watch and Bluetooth earbuds.

I’m using a pinetime and loving it. I use a Garmin Forerunner 735XT for training only with gps but it’s battery life is superb.

I wear a Forerunner 735xt, time for anecdata! It may be bigger than a band but it's surprisingly small and very light to the feel, I barely notice the difference with the Fitbit Charge HR 2 I owned before. Major reason why I'm not upgrading to a Fenix of something like that. Plus up to 15 days on battery when not using GPS, much more if I disable continuous HR.

I’ve only used the Garmin and it’s pretty good. The 735XT (old model) is still serving me well, though the battery is dying. I did get a 935 but something was wrong causing it to keep restarting. Apart from that it was fine, though.

personal experience X a bit of personal research on the matter: - deep sleep is restorative (AIUI the brain needs deep sleep otherwise it poisons itself, whereas e.g muscles don't, they need rest) - light sleep is important too but I feel that was not the question - I noticed I had a hard time falling asleep early/at "normal" hours - even if I did, waking up before 9am made me feel terrible through the day until 4pm, even though I had 8-12h of sleep - I got a fitness device (back then fitbit charge HR, now garmin forerunner 735xt) for unrelated reasons but figured out any data could be helpful as long as I'm aware of the limitations and error margins. Either device I had/have cannot record REM sleep, only deep+light+movement (via HR monitor+accelerometers) - over five years, data shows that either I sleep no earlier than 1am, or when I sleep before, it's only light sleep and a lot of movement, deep sleep starting between 1-3am - also, attempts at imposing myself an earlier sleep schedule (in order to get 8h of sleep given I started work at 9am) resulted in worse sleep/later deep sleep - sometimes on a given night, cumulative deep sleep as reported may look to be enough (e.g 3-4h) but looking at that night timeline graph showed that it was extremely segmented instead of a couple or three chunks - even if I'm extremely tired I cannot sleep before 1am. it's that or I sleep at 7-9pm and wake up within an hour after 23pm, theb can't get back to sleep until 3-4am - exercise helps (…

The good thing with my current bike is that it never runs out of fuel, by design. I can pick it up anytime and it just works, it was so 10 years ago when I acquired it, and it'll be so 10 years down the road. I have a Garmin Forerunner 735XT watch and it needs charging every 15 days, which is better than any "true" smartwatch out there. At some point in the distant-but-not-so-much future the battery will flat out die and there will be no replacement part. The experience from my mechanical watch is entirely different: it keeps on ticking as I move around, and the thing will probably end up surviving me. Going from zero to non-zero - whatever the value of non-zero is - is non-negligible mental weight. Zero is a freeing experience.
