Hello dear forum members,
My late grand father was a watchmaker as a hobby, and we've recently gone through some of his old watches and came across an old Girard Perregaux.
There's no indication as to which model it is, and I did not open the case physically to see the movement - so I have no idea which model it is.
I wanted to ask you, respected members of this community, for help identifying the model and year of manufacture.
I'm attaching a photo of the watch to this post. (The wrist band isn't original)
Thank you all very much,
