Fitting new crowns to asian stems

[vintagerolex]

I am looking to replace some of the crowns on my Rolex reps with OEM or genuine parts. It just occurred to me that they may not fit on the stem of the asian movements.

Does anyone know about this?

Cheers.

I don't know specifically about rolex movements, but I bet they all are the same.

And -- thanks to the Tao -- asian stem use to be standard size as all stems: 0.90mm for auto movements, 1.20 mm for manual movements.
