To solve this problem, what I did was disassemble the bezel of the watch and paint it with a matte black spray, I'll give you photos of the before and after, think that if you paint it you will lose the numbers of the bezel, I put a bezel on top The one that carries the clock, to disassemble them you just have to remove the 4 screws that it has and lift it carefully
if you have it very damaged you can polish it and paint it later
