Hi Gary,
Why don't you try to contact the company? If this is something significant piece of their history, they should be willing to put effort in researching their past database.
Here is their contact number:
Universal Geneve S.A
38, Chemin du Grand Puits
Case postale 128CH-1217 Meyrin 2
Switzerland
Phone (+41 22) 307 78 80
Fax (+41 22) 307 78 90
Unfortunately they don't have Museum Curator like Omega (Marc Richon)
