Hi out there. I have an early Eterna manual wind movement which is marked '710' on the top plate and the backside of the dial. I'm looking for parts for it now and not finding any reference to this calibre number. Does anyone have any wisdom to share on this? Is it equivalent to an other calibre? I need a new barell / mainspring. As always, many thanks in advance for your help.

Hi there,

the ETA equivalent is the ETA 715. But since this has no covered winding gear, I'm not sure whetehr it has the same barrel.
