Girard Perregaux

Hi All, I'm a novice at watch collecting, so please forgive the naivete. Tried unsuccessfully to learn about this watch on my own. Could not find a similar example anywhere. Unknown date of production. Some details that might be helpful and images below. ...  

Thank you. Once I have the reference number, is there a lookup site that collectors typically visit? Thanks

Why not ask the owner about the watch? That's the easiest route... Cazalea

Yes, I tried but have yet to receive a response.
