Left the Galaxy Watch world behind earlier this month.
Honestly, how many of us think about the actual personal use cases that we have for getting smart watches that actually influence/inform our purchases?
In my case once smart watches began getting BP monitoring & heart rate variability measurement functionality, that was/is my main reason for a smart watch purchase. Some context; I am a blood cancer survivor who suffers from long term chemo induced cardiotoxicity (hence a weak heart) & am hypertensive to boot.
GalaxyWatches worked fine for my use case using SHM mod which was nixed in the recent watch One UI 8 (iirc) update.
After plenty of searching on the internet looking for workarounds/solutions, I went ahead & bought this, the Huawei Watch D2.
The ambulatory BP monitoring works in every territory because it uses a physical cuff built into the watch strap & is medically certified. The results are very accurate if you measure in the postures prescribed by Huawei. I've checked the accuracy using an Omron arm cuff monitor as well as a Beurer wrist cuff monitor. The readings are consistently within a +/- 2 mmHG on all 3.
The display is much brighter than my erstwhile GalaxyWatch 5 Pro. The battery life even with hourly BP measurments, AOD, GNSS & a perpetually on bluetooth connection is more than 4 days. The call clarity is miles better than it was on my 5Pro. Notification sync is near instant. Heart rate tracking is more accurate than Samsung as well as sleep tracking.
The watch does require careful physical handling when taking it off & wearing it because of the integrated BP cuff.
What I miss, the ease of being in a seamless ecosystem, the huge variety of apps & watchfaces on WearOs, the huge ROM (D2 only has 4 GB & primarily for health records) that allowed a ton of on watch music and the wifi connectivity.
OTOH being able to keep an eye on my heart health again makes foregoing the above worthwhile.
