Mine turns off in the dark so that may help. I based my remarks off the manual. Good to know they’re pessimistic.

It’s not that inconvenient considering how shitty the Signal desktop experience is: it’s slow, bloated and has moody sync.

SimpleX is anonymous and works well.

The plain old digital ones with solar + radio time syncing are the best tool watches on the market in my opinion : set and forget, it even does DST automatically. The only limitation is you have to be outside during the day with the watch exposed a few hours a month or cheat with other light sources.
