We didn't get much response then, so I'm not sure if many people will be able to help you with this enquiry either. Are they the same watches as the previous poster had? I imagine they are, I wouldn't expect Swissair to have too many different models.
Hi. I had a response from Longines Museum, that there were 5 "Swissair Exclusive" models, 2 are on display at the Longines Museum. As mentioned in previous post, I happen to have all 5 of them, and I also posted their pictures. The 1st I believe was sold on Swissair long haul flights, late 80's, because the 2nd one (Swissair Exclusive #2) I bought personally in 1992 on a flight from Zurich to Chicago. The others were bought on Ebay, and the last of the series, #5, was bought in a flea market in Zurich. Other than that - I have no information.
This watch was sold in the early 1990's on board Swiss-Air flirts from Geneve ( anyway ) to the US, when you purchased a watch , the pilot would sign a special certificate that it was purchased on board during the flight.
If you have one, do you have all the documents like I described
