You can also configure PimeTime to have an always-on display, and it should even last more than a day.
replyA Garmin memory-in-pixel eInk (MIP) watch? Lots of choices there, since about 2015. Modern versions (MIP not AMOLED, the category is getting confusing) last about 10 days on a charge.
replyWatches with color memory-in-pixel displays have existed since Pebble.
