Hi Guys,

I'm hoping one of you would be able to lend some expertise. I recently inherited an old Heuer from my granddad. I'd like to find out some more information about it.

I've taken it to a vintage watch specialist in London and he wan't able to tell me a great deal about age or its history. He tried opening the back with a rubber grip and couldn't get in, which suggested to him it's not been opened before and all the parts on the face are probably the originals.

He also said that despite the strap material breaking down, it doesn't look like it has been worn much. The watch was found in a box in a drawer in a basement and I don't ever remember my granddad wearing it so this may well be true.

I wondered if anyone could help me identify it? And any rough indication of worth?

Thank you in advance
