While I don't have one, I went down the pathway to replace almost a decade of using Pebbles , looking at PineTime, Bangle.js, Amazfit, Watchy, etc...and I just settled on buying a replacement housing for my Pebble, pushing the problem off to be dealt with in another 5 years.

The battery life on Watchy leaves a lot to be desired, as does the lack of a water-resistant sealed case, but the full featured hardware is a real contender.

The Bangle.js 2 is my second choice in the line up of open source smartwatches.
