TIn Gemini V mission, together with Gordon Cooper (see Bulova Accutron section), Charles "Pete" Conrad also participated. He worn his Glycine Airman watch. With the same watch he was also a part of Gemini IX mission in september of 1966. On that mission Conrad was actually for two hours and 41 minutes exposed to the open space while controlling the EVA of his team mate Richard Gordon. So due to this fact Glycine Airman is supposed to be the first automatic watch being worn in the open space.
Glycine Airman was released in the mid fifties and was a very popular watch among US military personal. At first Felsa 692N movement was used, then from 1963 A.Shild 1701 followed by A.Shild 1702 and 1703. The backplate changed together with the movement change. From 1967 on the dial above the Glycine sign also the Glycine hallmark (crown) was printed.
I tried my best to figure out which version of the Airman was actually used by Conrad. From the year of his first flight my best guess is that that was one of the earliest versions with the A.Shild movements. And that is what also I have. My watch is dated in 1965.
Due to the big success of the Airman, Glycine continues with the Airman models even today. Huge amount of different version were developed. I also used to have one modern version of Glycine Airman, but that was sold already before publishing my watches on this web site.
