Rolex movement rattle when shaken, why?

That could be the clutch slipping to prevent overwinding when the watch is fully wound.

Newer Subs have the new movement with ceramic ball bearings - one side effect is that they are louder (rotor movement) than the older movements...

31XX movements had no ceramic ball bearing rotor but a rotor axle - that would only start making noise when it was worn out or damaged.

32XX movements are louder out of the box in regards to Rotor noise.

Since your watch is 3 months old - it's normal to be loud as it's a new movement with the 70 hour power reserve...

Enjoy it :-)

There is no clutch, that is just the mainspring slipping in the barrel when fully wound.

Isn’t that called a slip-clutch?

I also read that some automatic winding mechanism decouple the winding rotor when fully wound. I am not an expert though.

Anyhow - point is in Rolex and Tudor watches you generally can hear that slippage occurring when the watch is fully wound.

A clutch would couple/decouple something, like for instance in a chronograph.

The mainspring has a small bit extra spring on the end that creates friction with the barrel wall and its grooves when fully wound, that is the audible clicking.
The automatic module does not get decoupled when fully wound.

Well the mainspring clutches the barrel.

(A notch in the barrel clutches a kink in the spring).

When you reach full wind it slips.

Sound like a slipping clutch to me


To the OP.

If you remove the bracelet does the watch head still rattle?

Just a thought.

That's a internet myth there is no clutch, all that happens when mainspring is fully wound it just slips in the spring-barrel, just like it would do on the wrist.

Ok, you never stop to learn, thanks everyone!! But for the OP the slipping of the mainspring could still make that sound.

Rolex pendulums run on ball bearings (or they did) and these bearings either wear away the race they run in or the race becomes damaged due to watch falls, causing the pendulum to acquire lateral/horizontal movement and this causes said rattling and scraping.

It’s happened to me twice. 1 x Daytona zenith and 1 x 16610 sub. The only remedy is a new pendulum, since the bearings are not serviceable. Both times mine were replaced free in the RSC service.

Hi inadeje, I'm new here, thanks for the nformation.
In your case what was the cause of the loose pendulum. Was it due to an impact?

It’s hard to know without hearing it ourselves. The 41 submariners do have a noise of the rotor sometimes. All watches to make some kind of noise, like I said, it’s hard to know, exactly without hearing ourselves.

Hate to break it to you people.
This thread is rather ancient.
