knocking noise when shaken

[Trailblazer]

Hi guys,

Tried searching for old threads but failed.

I had just discovered my z serial 14060m gave a knocking noise when shaken on empty power, it can be felt and heard..its like a loose matter inside but its more obvious when case was tilted at a certain angle.

Now that its manually wound, the knocking seems to disappear.

What's going on guys?

I would let a watchmaker have a look at it, perhaps an easy fix, otherwise nothing wrong with a full service.

I never shake my watches when they're not wound...

Hi, why not?

I would stop shaking my watch and see how that works.

If you're worried just bring it to service.

Expect what you can hear is just the rotor pendulum swinging on its rotor bearing axle when you shake it.And always wind the watch no need to shake unless movement does not start after a wind sometimes that may happen again that's quite normal.But if watch is say well used daily and over 5- 7 years old and not been serviced then the achilles heal in the all 3 series movements is the rotor shaft.Its because Rolex still don't not use ball rotor bearings rotors for most of there watches (now present in the new 4130 Daytona).Instead, there use a plain sleeve bearing,which is very efficient in winding and quiet compared to some movements but still can be heard, but it has its weak points, and proper lubrication is critical so important to service every 5-7 years. When the lubricant evaporates or migrates, the metal axle experiences wear against the rotor shaft jewel bearing.Replacing the axle if worn will solved the problem,most Rolex watches have rotor axles with different size pivots at the ends. The one nearest the rotor is usually fairly large, but the one nearest the movement is relatively small,IMHO this is a Rolex movements weakest point.Today Rolex lubricates this with special grease,now this grease tends to dry-out especially in warmer climates and when it does, the rotor pivots are left without any lubrication.When the pivots become worn,or from lack of grease the bearing is able to move excessively from the normal plane of motion that makes the very slight rattle noise,and sometimes rubs on the case back.But in general the sleeve type Rolex rotors are quite problem free and some go on for many many years without trouble but others fail, but its doubtful if you have a problem..

so bottom line is what you are saying is that the Daytona is the superior Rolex watch!!

Most definitely not.
