Rolex cal 4130 Ceramic Ball-Bearings Rotor?

[timuS]

Hi,

This is a question that has been rattling in my mind for a long time now - Does the Daytona 4130 movement have a ceramic ball bearing rotor?

I asked my AD, but he doesn't seem to know...

Any information on this?

Would greatly appreciate your inputs!

No S.steel just like the rest of the Rolex line but like you say it has a ball bearing rotor bearing shaft, instead of just a plain shaft in most other Rolex.

Thanks for that information Padi! Thats one doubt cleared, though i still wonder why Rolex didn't use ceramic ball bearings in its flagship chronograph modules, 4130 & 4160...?
