I've mostly moved on to screen-less wearables for health metrics now. Not only do you get a ridiculously large battery life (measured in days) but I also found that it means more time and attention was put into the things I care about versus trying to support whatever garbage wearable OS they try to integrate with (or worse, roll their own).

My Garmin Instinct 3 Solar watch (which has a display) has a battery life measured in _weeks_.
