Even though I tend to agree to some extent, I've been using a Garmin descent G1 for a couple of months now and I'm super happy with it. I work at a dive centre so I dive every day and it has been very reliable. It feels more like a dive computer that ends up working as an activity tracker rather than the other way around.
I work at a dive centre so I dive every day, so I was looking for a computer that could double as a smart watch as I'm used to having one and that way I wouldn't have to switch between the two every day. I got a Garmin descent G1 a couple of months ago and I'm super happy with it. It feels more like a diving computer that you can use as a smart watch rather than the other way around, and I got it for 400€, which was a steal for all of the features it has.
Yippp been wearing the G1 solar for 4yrs now. Scuba, apnea hunt, swimming, and running, garmin has me for life hahaha Also the golf app is awesome and free. It learns overtime.
I am completely with you on this. My husband and I have both worn the Garmin Descent G1 every day since may. Charge lasts three weeks, even after logging several dives. And I also use it to track my golf shots. Incredible watch. Also, through BCBS insurance (and some others I’m sure) I was able to get a 20% off coupon.
Second the Garmin Descent series. I daily-wear it and use it for diving, running, cycling, golf, and health tracking. The air integration is superb. Battery life blows all other smart watches out of the water - up to 24 days between recharges.
Fenix 7 Pro, Sapphire Solar MIP and no burn-in problems
Not a smartwatch person, but I used to wear my Garmin 24/7 before getting into watches. Now I wear my garmin just for running/cycling/sleep. My automatics are worn the rest of my day. My garmin tracks sleep length, HR, HRV, and sleep cycles. I’d say wearing it to bed is the #1 contributor to me cutting back on alcohol. I didn’t realize how much it disrupted my sleep length and quality until I saw the stats in front of me.
Correlating the decreased REM, and increased number of “micro wakes” (that I didn’t even remember), to drinking was huge for me. I didn’t even realize that I wasn’t having dreams on nights I drank until I paid attention to my watches sleep cycle reports.
