I've been using one of the Xiaomi Mi bands (using the third party app Notify for Mi Band) for ~6 months and it's been good. Battery lasts ~1 week, tracks sleep, SpO2, lots of watchfaces for free, no subscription. Unfortunately the overall physical look, shape and band isn't that great for everyday wear. I could buy a regular watch for everyday wear but I'd rather kill two birds with one stone.
I've checked the recommendations in other threads but they weren't very specific or descriptive.
Preferences:
Up to ~$250 (used is ok).
Not Apple specific.
Round dial not square and preferably not a huge dial (not > 46mm).
Workout/sleep/SpO2,etc. tracking.
Don't care about: battery life, LTE, NFC, making calls/text notifications, google/strava integration, big screen, or playing music.
Must not have ongoing paid subscriptions for features.
Thanks <3
