I think the smart watch market is fascinating. On one hand you have Apple, with one design and software innovation and on the other hand you have a multitude of watch designers producing a variety of different looking watches at different price points using comparatively mediocre Wear OS. It also highlights the advantage of designing your own chips because Wear OS has been constrained by slow chip development by Qualcomm.
BTW, if one is in the market for a Wear OS watch, wait until when watches with the new chips release later this year, early next. I know a number of new watches are being released to coincide with the new version of Wear OS coming next month, but I expect the new chip to provide better battery life and processing for the future.
