For my next watch, I'm hesitating between the 6 and the 6X.
I am 53 years old and I am quite strong prebyte (badly to read telephone without glasses for example). As I don't always run with my sunglasses adapted to my eyesight (at night, I don't want to ...), on my current watch I am using 3 or 4 data per screen.
Is there a big difference in readability between the 2?
Is the 6 sufficiently readable, in particular the cards for a person with correct vision (and with my glasses for me obviously) or is the 6X really better on this side (but also heavier and more imposing)?
Finally, do the 6 pro solar and 6X pro solar models have strictly the same functions and do they evolve in the same way?
