Girard-perregaux 1960s Automatic

Bought this watch at an auction..Pretty cheap and runs, but certainly needs service.However, the metal O ring in the back which screws and holds the case is pretty damaged and tends to fall out.I don't know if this can be fixed or if I have to find a new one.And I don't even know if that's possible with such an old watch.I'll take it to my watchmaker, but any suggestions would be helpful.I looked on ebay and was not able to find something compatible. By the way, a definite redial, as I am sure you have all noted, but I think this redial was probably done decades ago..you can tell by the lettering.It's not crisp like you see with a truly original dial.But I think the rest of the watch is probably authentic
Thanks Artis

Let us know what your watchmaker says. My guess is they can replace the ring with a donor from their pile of parts acquired over the years

I assume that ring is threaded, and if so it's a pretty specialized part. You can keep an eye open for a replacement, or a parts watch. I predict you might find one within about a decade.

Finding a ring is going to be difficult. That kinda looks like "you need a donor watch" kinda thing, and doesn't seem too common.

You MIGHT actually have better luck measuring the threads (diameter & pitch) and seeing if you can find a more-generic/off the shelf one to replace it. You'll lose the stamping, but it'd work.

IF you were able to find something like that, AND you have a lathe, AND it was about the right shape, you MIGHT actually be able to turn the middle out of an existing case back. Not a trivial task, but one that a watchmaker might be able to make.

Thank you great advice
