Where to source a silver date wheel for a 1680 (Cal. 1575)

[Corleone11]

Hi there,

I hope this is the right place to post as it is my first time posting here. :)

I just wanted to ask where the best place is to source an original date disk for a (Red) 1680? The date wheel in mine has been retouched previously and even though it's not visible when wearing the watch, I'd like to replace it with an untouched original one with the open sixes again.

Cheers!
