@popperini: Yeah, I know what you mean. What I meant was, as OP already said that they can't get the original bezel, finding an alternative substitute that is not exactly the same might be better than just throwing the watch away (I had a really cheap Tudor Black Bay from Aliexpress, and the numbers on the bezel were literally put on with transfers...in the end I did end up throwing it away, as half of the numbers had come off and it looked pretty horrendous!).
Your idea is good though (and easier/cheaper compared to replacing the bezel). It looks from the pictures that there are no idents, but it still might be worth it if OP can mask off the edges with tape or something similar. I don't know, bur perhaps there are modders around that specialise in this type of thing?
