Guys i have the same issue of you all, but i think this have another cause.
The bezel numbers are not fading or loosing color with time, but is the paint that the repmakers use that are super oleofobic.
Every touch of finger turns the numbers a little bit dark, something that the real R paint doesn’t do.
BUT there is a solution: this paint is SUPER EASY TO CLEAN, and to do this you only need dishsoap and a thootbrush.
Try yourself and tell me the result, you need like 2 min. If your watch have “never touch water” this is the problem. It catch all the hands oil and dirt.
I have to do this on mine every week of use to keep the look “white” (watch used all day 10 hour per day)
If you want I’ll do a before and after next time I’ll do it.
