Not uncommon for people into watches to wear a "real" watch one wrist with a fitness tracker on the other. I did that for years before selling my mechanical watches to buy bikes!
If you're going to go that route, I would suggest the Garmin Vivoactive because while it does have some issues, the (free) HRV tracking you get with compatible Garmin devices provides interesting and useful insights to stress, fatigue, and general health.
