Service for Noisy Rotor

[iceshark099]

Just received an Ebel 1911 Panda and the rotor is pretty loud, does a service usually help that out or do I need to do something else to quiet this thing down?

Thanks

Loud compared to what..???

Virtually ALL automatic watches have rotors than can be readily heard when turning....That's how the watch gets wound..

Unless the noise is really loud, and "scraping like" it's usually best to just get used to it...

There should be a "sticky" about this issue, since it seems to arise every few weeks over the past 5 years or so....

if its a 21J, they are pretty loud usually.

thanks, seems like it is pretty common, wont worry to much about it!

I always take off the rotor and put a drop of mobius on the bearing on an A21J

If it's an A-7750 and you can replace the rotor bearing with a Swiss ETA bearing. Some rotors with saw-tooth bearing you may have to have them machined a bit to accept the ETA bearing. It will be silent after you do this. If the watch is a keeper and has a display caseback it's a must!

Just remember that Swiss 7750 can be loud too

Agree, ETA 7750 rotors in my experience are very loud, I haven't noted any difference in the noise between the A7750 or an ETA7750...

The Rotor may be loose. I've had 2 watches arrive that way.

yeah.. that happened to me and the rotor was loose. is it winding properly?
