Tudor 76100 submariner crown part number

[PsychoDogBeast]

Hi there all

I have a Tudor 76100 blue submariner which ive owned for many years. Its in fantastic condition apart from the crown is a little beat up (a poor service before my ownership where someone had pushed against it with a bezel knife and put a big mark in it)

The watch is due a service as its losing time, so its a perfect time to swap the crown, but I am unsure what to buy.

I would guess its a rolex sub/sea dweller crown of the same sort of era early to late 80s. If someone can confirm this that would be fantastic

Best regards and thanks james
