: Apparently there was a ca. 1109 but which watch
: it was used in is unclear.
Thank you so much for the response Dave and the info links. Gosh, those are beautiful watches in your link article. I checked the vintage watch database on Omega's website, and found two watches both Seamasters that popped up in the search for ca. 1109. Both were in the early 1990's. I called up my friend who was selling the watch (he is a watch collector) and he claimed the following: 1. The ca 1109's were used around late 1980's to early 1990's. 2. The Constellation I am looking at is an old model, and does not have the star as some old model's in that period did not have the star below the Constellation Chronometer label on the dial. 3. Some old model Constellations from that period did have see through backs. 4. The blue colored stick hands on the watch are because its old model and different from the dauphin hands in the new model Constellations. He claims he knows his watches and is very sure of the authenticity of this watch. I tend to believe him, but I would really like to make sure before making the purchase. Any more help, anyone? And thanks again in advance.
