Hi, congratulations with obtaining a great watch, I own a 3536 in Titanium and absolutely love it! I'm not a restoratoin expert but:
- the bezel is attached with 2 tiny screws under the edge, opposite to each other (to be seen from the side of the watch), so you can remove and clean it.
- you didn't attach any pictures (can you still do that?), but the top of the numbers/marks on the bezel are 'metal' colour and the black in between should be really black. Can't remember ever seen a faded or discoloured one....
Please post pictures once you received it!
Regards, Bob
