This seems like a no-brainer, especially for the longer-duration timers. My watch-47mm shows the time in the upper-right corner while I’m using the Indoor Run app. It should be able to display the time while the Timer app is running, as well.
It’s a watch. Its primary function is to tell time. Let it be a watch and show the time even when your (Wyze’s) preset 60-minute countdown timer is running.
