Rolex crown / case tube sizes

[newf]

Hi, Folks,

Does any one know the different crown sizes used on the models of the Rolex reps such as that used on the DateJust, DayDate and Yacht-Master?

It seems as if the case tubes are different sizes also.

Any info greatly appreciated.

For a real Rolex, the 6mm crowns and tubes are what is used- like the 24-603-0 or the newer 24-604-0. Rep crowns for the three models you mentioned are 6mm of sorts and can vary from manufacturer to manufacturer. And a rep crown won't fit a gen case tube and vice versa.

Not sure, but isn't yacht master crown ref. 24-703-0, same as modern sub? 7mm..

I'm thinking the Yacht Master 16622 is a 6mm crown and WR to 100m. The new Yacht Master II might have a 7mm crown. Of course, I can't find the 16622 on the list....

Oops! I found it at the end of the 7mm list- 24-704-0- the latest 7mm crown- interesting- I would have figured 6mm like a GMT.
