You can pop it off very easy. Just take a little plastic knife and put it between bezel and case. Now you see the click spring. Just bent the little noses a bit more and put the bezel back on. This helps a bit
I live in a town where Rolex and PAM is present all the time. In the Subway, in a Restaurant...everywhere!
But I've never seen a Fiddy in the wild (besides some ugly reps)
So F..ck the flaws! Nobody will ever call you out!
If you've never done something like this before, just let the watchsmith do the job.
All you need is a little plastic tool to get the bezel off and two thumbs to get the crystal out of the bezel.
