So I got a PAM111h (modded by Goin and sapphire crystal added) from another forum member. I absolutely love the watch but the crystal has a couple of faint marks/scratches? around the 10 marker (just north of the second hand). Is it worth replacing the sapphire crystal on it or is there a way to buff out the marks? or should I just deal with it and look in to moving to a 111N v3?
