Rolex Sub C crown

[eah990]

I was just curious for the watch makers on this forum or anyone with experience. If done properly, no cross threading etc... how many times could you screw and unscrew the crown on a new sub c before you would notice the threads becoming worn? Are we talking a few hundread times? few thousand times?

Thousands done right.
Over tightening can stretch the threads slightly each time and reduce the tube's life.
Tighten til snug - not 50#ft. of Tq!

Exactly right..

You know, many of the early Oyster Rolex watches were manually wound.. So, you unscrewed the crown every day, wound it up, then screwed it back down again...

Lots of those watches are still perfectly functional today..
