The Garmin fenix 8 51mm is a nice upgrade from the fenix 6x pro. Clear screen, extensively adjustable in terms of settings so that you can almost completely customize the watch to your own hand. Price is a bit high, but with a 2nd chance that had no damage it became a lot more interesting. Many sports profiles available.

My eyesight is getting worse, but with the large screen, I can enlarge the text. The battery life is excellent, so I don't have to worry about going out for a few days. Wearing it does take some getting used to, given the large screen and weight, especially when exercising. So, the watch strap needs to be properly tensioned.
