I’ve owned the Amazfit Bip smartwatch for well over 1 month now and it is the device that resides on my left wrist.
The battery life is phenomenal at greater than 30 days (I only use GPS minimally,) it has various different watch faces that can be installed (with many others available from 3rd party sources available for download and installation,) and it is stylish and comfortable to wear.
It has continuous heart rate mode that can be turned off or set to automatically measure at 1, 10 or 30 minute intervals or can be set to “Sleep assistant” mode which only measures while you are sleeping to improve sleep tracking accuracy.
It has become my main device, although it still comes off and the Atlas 2 goes one when I’m in the gym.
Definitely a great watch at its price point.

Great for kayaking in terms of GPS tracks and total mileage, but it does not count paddle strokes as steps, unfortunately. For that I wear the Lemfo LT02 on my right wrist while paddling.
Update: While testing the Bip alongside a different fitness tracker, I moved the Bip to my right wrist and then it actually counted paddle strokes as steps on my right wrist when it had not previously counted paddle strokes on my left wrist. So as long as you don’t mind wearing it on your right wrist while paddling (be sure to tell the app which wrist it is on) it gets the job done.
