Have some question about omega service

A rotor is not considered a wear item so it is not included in a basic, although comprehensive service. It is considered a worn part analogous to damage.

I have had my rotor replaced twice on my Solar Impulse, both times it was included in the price. It must have something to do with caliber number or age. The next time I send my Solar Impulse in they will need to replace the rotor again, as it is again making abnormal noises.

I seem to recall Al indicating the bushing is NLA and they are only selling the rotor complete.

They are available. There was a time when I couldn't seem to get any but they have been pretty consistent with supply for a few years now.

As for the entire rotor needing replacement, it does happen, in particular if someone has tried a bodge repair to the pinion, like using a 3 corner punch or something similar to try to close the hole. I've had a few where people have screwed around with them enough that the hole in the rotor itself ends up oversized, and the new pinion is too loose when installed.

BTW the new rotors don't come reamed. Omega used to sell a set of the rotor and axle, and those were once reamed to fit each other at the factory, but they no longer do this. You might get lucky to find an NOS set somewhere that has been reamed, but I always count on reaming them out.

BTW to the OP, Omega is the last place most collectors take their vintage watches. I personally would advise you to get it back and take it to a watchmaker who will preserve the vintage nature of the watch for you if that's what you want. Omega will possibly change parts that will drop the value of the watch. The 55X/56X series of movements are easily serviced, so there's no need to send this watch to Omega really.

Cheers, Al

This is an indirectly driven seconds hand, and often if the friction spring for the hand is not set correctly or is damaged, the hand will not move smoothly. This would be resolved during a service.
