I bought a second PTS back in the day, and kept my original as a backup. I just recently had to switch back to it because the daily driver couldn't hold a charge anymore.
I tried looking for a replacement smart watch that could do the things I need it to do, and there's still not one on the market at any price point that can do
Always-on color display
7+ days between charging
Notifications with full messages on the watch
Ability to respond to messages from the watch via both canned responses and voice dictation
Smart alarms (activate up to 30m before alarm time, if watch detects you're no longer in deep sleep)
Google Fit dev APIs shutdown set, fate of Android & Wear OS apps go unannounced ( 9to5google.com )
