Sounds like someone, has a little better then average horological knowledge. Sure wish I could stumble on to a 1000 dollar PP Chrono. Back in the early 90's I did come by a 1946 AP (time only) 2 tone rectangle rose & yellow 18K case mono'd J.D. The story from the old gal who consigned it was, it was given to her by Jack Dempsey long ago when she was one of the many pretty girls who went on dates with the guy. I contacted AP and they could only tell me the watch was sold to a Chicago jeweler in 48' and that jeweler at that time had been out of business around the last 40 years.. I could never come up with the prof I was hoping to get on that AP. Later on I took it in for a new main spring at the watch repair guy I used. I got a call from the watch guy a week or so later and I think my watch guy contacted this collector when I brought it in, because, I think my watch guy and this collector had a deal going to notify this collector when something interesting came in. I thought this, because the watch guy called first, to tell me, the first main spring installed was very thin and failed from the get and it may be a problem to find one good enough to hold. Then a couple days later the watch guy, called again to tell me this collector, just happened to see it on the bench and wanted to make me an offer on it. I did go ahead and made a deal with this collector and I did make a little over a grand on it.
As for this PW I've always referred to these as "Swiss Generics", so do what trdking says and you should find out more info on it. It is a nice pocket watch IMO, but not something a serious collector will pay big bucks for.
