Hmm I believe the best route would be to check online watch databases and if that doesn't cover, then buy a catalog on eBay.
There is a huge online database (that I can't find now...) with various sources included. Perhaps someone will be able to drop the name here.
A question for the GP enthusiasts
I believe this is a picture from the 1994 GP catalog (or an ad from the year). Can anybody identify any of the references besides number 4, which is the 2550? I'm particularly curious about #1 and #3. Much appreciated ...
A simple answer....
... is this page being part of a 1941 catalogue. It´s not 1994. But in fact reference 2550 (introduced in 1994) goes back to the 1940's watch. Greetings from Germany, Peter
