I had a Lezyne Micro GPS (enhanced). Was super reliable and small footprint so hardly took up any space on the bars. Very good battery life 10+ hours. You don't need a big screen I mean who the hell wants to see all the metrics on one screen anyway? Just show the most common one (heart rate?) and maybe one other metric,then hide all the lesser stuff on a secondary screen that you scroll to when stopped.
Now I have a Garmin Instinct watch and it is fantastic. Even less clutter on my bars without anything on there. Very reliable, a huge long feature list, super long battery life (2 weekend rides plus wear it all week including mid-week workouts). Monocrome high contrast screen. Built to be bombproof. I used to wear a g shock watch when I rode, so having something on the wrist is not an issue.
