Over the years, I have purchased a few bands via Amazon, Clockwork Synergy, Nomad, and a few other websites. However, after a few of them had the connection part to the watch (AWU1) starting to slip (coating on connection seemed to come off), I decided to only use Apple official watch bands.
When I purchased my AWU1, I only used my Apple Watch bands from my AW6. At the start of this year, as I was cleaning out drawers (as you do, switching years, LOL) I decided to try the band that came with my AWU1. I've been using it ever since. To add, lately, probably as I am getting older, I keep thinking, why do I need multiple bands? Why do I need so much 'stuff' in general. Thus, trying a different approach to things...
