Need help for this Rolex 3035 cal. Rotor

[Oyster]

Hi everyone,

I got a little problem when winding the crown the rotor will spin, and it's very stiff. But when I removed the auto mechanic the crown turn smooth, might be the cilp that hold the rotor ?

Don't have the specifics on that movement in front of me, but the scenario you describe sounds like you have a problem with the reverser system. The reverser wheels do lots of spinning and if they get just a wee but dirty you can end up spinning the rotor when you wind the crown. Some calibres have a different clutch mechanism, but I would bet on the Rolex you have a reverser wheel stuck... Time to disassemble, clean and inspect the automatic work!

Took a quick look at the tech specs for the 3035. It has 2 reversing wheels. If one/both are not functioning correctly then the rotor will indeed spin when you wind the crown.
