@gdir You guys both say 'fast charging', but what does that mean exactly? I used the OPW2 for about 2 weeks before my OPW3 came in the mail and I compared with both chargers. The 2 charger was slower by about 10-15mins on each watch. With my 3 charger the most it ever takes is just shy of an hour, about 58-59 mins, and that's from 0-100%. If there's even 5-10% already on the watch when I snap it on it'll take 40-45 mins. So with using the 2 charger, that would be 1hr-1:15hr. I know 15 mins doesn't sound like a lot, but I never have to charge more than an hour, and that's huge to me. It's the fastest charging watch with 2nd to longest battery life, while still being the most capable I've ever used. I've used Garmin, Fitbit, and this OPW3 over the last 10 years. (I'm not including Moto 360 watch from 2014, that was a failure...)
I think the OPW2 was pretty ass tbh, but the latest greatest insanely expensive watch having to go power save to get 3 days is pretty funny. But hey, if you like it that's all that matters.
Oneplus watch 2R - one of the most reliable and economical watch out there. I've been using it more than a year and it's dual band gps is very accurate, also battery life is great. The live data provides pace, time, heart rate zone, heart rate elevation, energy and music control. It provides more rich data in its mobile app - cadence, stride length, GCT balance - which are helpful in improving the running from and heart recovery. The price is around 12k now. also syncs with strava.

Love me a traditional watch so don't fault you, but there are great SmartWatch options out there. My OnePlus Watch 2 lasts 4+ days of straight use and charges back to 100% in ~30 minutes.
I've been on the OPW2 for a year and agree these are great, 4+ days on a charge and less than 30 minutes to charge it back to full. I basically only take it off to shower, but don't need to.
I got the One+ 43mm after much research. Absolutely love it. I can't stand all the huge watches and wanted something a bit smaller / slimmer. It's very full featured and looks good to me. And a hell of a lot cheaper than the Garmins and the like. My wife has the Garmin Lily 2 which is really small and she loves it. I'm not a fan of the monochrome display though but she's happy with it. For the record we'll never get a fitbit again - she tried them for years and they always developed weird software glitches after about a year and then became too annoying to keep.
I have owned android wear watches from the very beginning. Latest being in the opw2 and ticwatch atlas. I know alot of people slate the ticwatch however I have fully enjoyed it. Sleep tracking wise it actually picks up when I wake during my sleep which no other watch has.
