Hi All - I recently purchased a vintage Girard Perregaux. Can anyone take a look at the attached photo and tell me if they feel it's an original GP movement and case or if it's a "frankstein" watch with mixed parts (and which parts you think were swapped out). Also curious if any GP experts can estimate the year it was made. FYI - purchased it knowing it's a project, so I'm not so much concerned with condition, more focused on if it's authentic or not. Thank you!

We really need to see inside the watch to give you any information. Vintage GP’s usually have a logo engraved inside the caseback.

The hands seem to have been replaced, they look a bit long. You are also missing the small seconds hand.

It's hiding in the corner.

OP - Do you mind sharing what other watches you have in the background?

The case is similar to my late father’s early 1950’s GP tank.

Thanks for the response! Would you have any idea where I could possibly source the correct hands?

Not a clue and certainly not until we can determine which model you have.

Fascinating. That dial pattern resembles the Zenith logo.

Indeed. I’ve searched high and low for years to find another GP like this one. No luck. My mother likely purchased this in Winnipeg in late 1951, just before their first anniversary.

Clearly missing the lecture on tool watches, my Dad damaged the original glass and dial (dent is visible) while working in his store in the late 1950’s. I learned many years later that an attempt was made to see if a watchmaker might fix the dent but it was determined impossible.

The movement is damn near pristine.
