Case tube size for a Gen Crown?

[Snrubb]

Does anyone know what size case tube I need to put a Gen Crown on a rep case?

Thanks!

The Zigmeister should know. He had the thread on that 188 with a newly manufactured tube and gen auto crown fitted.

If you have a bead on a gen steel auto crown please let me know I need 2.

It depends what type of gen crown on which model watch. The current gen, handwind crowns will fit Jimmy Fu's case tubes - I have one on my franken preA1 which has a JF case & tube and it fits and operates perfectly.

What size is the Jimmy Fu tube?

I've got 4 genuine crowns and they all have differences. You really need to measure the crown dimensions and custom make a part if you want a perfect fit.

My solution is to machine a new tube on the lathe, drill the case to accept the new tube, press it in place, and install new o'rings on the crown to provide a tight seal against the tube.

^^ Best solution. Hands down.
