Found this amongst my wife’s passed mother’s jewellery. Any ideas knowledge of this era? I can’t see away of getting the back off. Any ideas?

Thanks in advance

Try removing the Strap and look in between the lug width if there is a point where you can insert a tool. Possibly early 70s to mid rough guess

I got my guess on an ETA 555 quartz movement which was used in the 70s

The fastest way to find out is to open the case back and get the movement serial number. You can then look it up in the well documented Omega Serial Number/Build Date index. That will give you at least the build date of the movement.

I can’t workout how to remove the case back?

It’s probably a front loading movement held in by the crystal, it will have a split stem so be careful. I would take it to a professional.
