@Tomas5 said: sky-runner for me readibility is good (37yo) but it is really small so it can be hard in few years I am 55 and still have a decent eyesight and not wearing glasses unless I need to read something in tiny print. But it would be unreasonable to expect me to wear reading glasses when using the watch. And without glasses it is extremely hard for me to read these labels. It may be not just the font size but the font type, spacing and outlines. I compared the labels between Suunto and Garmin. With nearly the same font size, Garmin labels are somehow significantly easier to read. Trail and ultra runners are in general older in age. The average age of ultra runners is 42-43 years old, and there are a lot of us in their 50s and 60s. Ultrarunners are one of the target categories of users for Suunto watches - people who are more likely to buy it because of the longer battery life and features. So in my opinion there should be an effort to cater to older users. Also, older users tend to have more disposable income and more likely to buy an expensive watch like Vertical 2.
