Help with a polerouter 69

Hello

I am having a dilema.

A few months ago I sent this Polerouter for service. The watch came back from service and in some positions I felt the rotor touching the case, very rarely but definetely happened.
I addressed this issue with my watchmaker. He said that it was normal for the watch with such age and advised me not to do anything.
Time passed, a few months, I haven't use the watch but I feel like now it is even worse. If the case is tightened closed, there's where you really hear the noise (facing up, off course).

What would you do? Take it to another watchmaker or go to the same and ask for a new "rubber" (sorry but don't know the exact word in english, the black rubber that isolated the case).

Thank you in advance

I think that a new thicker seal (Rubber) would do the job if the watch works correctly...

The only thing that the bigger case gasket does is increase the clearance between the case back and the rotor. The problem is that the wear and wobble on the micro-rotor bearing, will only get worse as it has more space to slap around in ... The good news is that first generation of micro-rotors (type 1) can be "reconditioned". If wear to oscillator axle is minor, by replacing the oscillating weight 1143/1 or the axle 1496 (or both if there is significant wear). If wear is dealt with early, it may be possible to gold plate both parts and ream out /polish for a perfect fit. alternatively, sleeve the axle, ream out the oscillating weight and insert a bush. That would be sufficient to give it another lease of life. They are all specialist jobs that have a good degree of success. However, as always, preventative maintenance and proper regular lubrication is probably the best all round approach as it will extend the life of the micro-rotor significantly. Later micro-rotors (type 2 - ball bearing type) are impossible to repair ... bearings are tiny and retaining spacer (which always breaks up) is impossible to re-manufacture without some very expensive kit.



A complete type 2 is interchangeable with a complete type 1. Parts are not. There is a great article on micro-rotors here ... well worth a read.
