Hello goodfolks! I am currently searching for what is the correct crown for an omega Geneve caliber 501, but finding information was harder than I expected. Is there a list or registrar of sorts where you could look at what crowns should be the right one? Thanks and have an excellent day.
Open the case (or have it opened for you) and get the reference ... then it's as easy as typing it into Google, clicking on "images" and looking through original examples. You can also try the reference in Omega's vintage database to see if there's a photo on record there.
