I have had a TicWatch PRO 3 GPS for 2½ years but in my head I have switched GPS to POS. Their watch/app combination keeps losing exercise and sleep records. Those that do make it to my phone only do so hours or days after the fact. I have now started using a Fitbit band to track exercise and sleep, but then I missed having the watch for talking with Google, starting timers, phone calls etcetera so now I wear one on each wrist.
It appears that Mobvoi has set a rough date for when it will start updating some of its existing smartwatches to Wear OS 3. For some reason, the company has left out the original TicWatch Pro 3, despite its similarities with the TicWatch Pro 3 Ultra and TicWatch E3.
