    Zenith Autosport: Should I Be Concerned?

    Hi,

    I have a Zenith Autosport with a caliber 2552 PC movement. When the automatic rotor moves it makes a sound and it spins back and forth if I 'move' the watch. Compared to my other automatic watches it seems that this one makes to much sound and I was wondering if this indicates that there is a (future) problem and if I should bring it to my watchmaker? Thank you for your feedback on this one!

    Can't see any telltale 'scour' marks where the rotor has been rubbing - look inside the caseback, as well – but generally the sound you describe is something that warrants a look. The bearing that the rotor rests on can fail and I'd have it checked sooner, rather than later. I love Autosport watches, by the way, and the 2552 movements are great. I have a couple and mine are pretty quiet, so… good luck. The good news is that parts are still available for it!

    The next question would be: does it still wind OK? I.e. does it build up the necessary power reserve quick enough? If not, something is not as it should be.

    Hartmut, in my opinion that is still the case although I am not sure what should be qualified as the 'necessary power reserve'. F.e. to 'create' this topic I had it on my wrist around 3PM for 30 minutes and now it's still running without any time deviation as well.

    You show a picture of the movement so presumably you can get at it. Does the rotor wobble on its bearing? Are there scratches on the inside of the case back that suggest that the rotor scrapes on the back? If not, I wouldn't worry excessively. Alternatively, a decent watchmaker should be able to detect any problems.

    Thank you Hartmut, I will do a 'daylight' check tomorrow for a close inspection if the rotor is wobbling on the bearing and if there are any scratches on the inside of the case back.
