ETA 2783 keyless


1680

Recommended Posts

Hello,

 

today I worked on a ETA 2783 for the first time.

 

I had a bit trouble with the keyless, it seems all levers are in the correct position I can switch from winding to time setting position.

But when it's it winding position I need to apply a bit pressure onto the crown to wind otherwise the crown will spin freely, when it

is in time setting position I need to pull the crown a bit whilst setting, otherwise it does not work/set properly.

It seems that the sliding and winding pinion don't engage properly and jump over.

 

I couldn't find any oil charts or similar, so I am not 100% sure if there is any part missing...

 

Does anyone have documents or know this kind of problems? I would be really grateful!

 

 

Cheers
