Glycine watches

Glycine was founded in 1914 in Biel/Bienne, where it is still based. It was among the early producers of automatic watches in series, and the earliest Airman models used the Felsa Bidynator automatic movement.

The Airman, introduced in 1953, has a 24-hour dial and a rotating 24-hour bezel that allow a second time zone to be read; it was worn by commercial and military pilots in the 1950s and 1960s. An Airman was worn on Pete Conrad's spacesuit during the Gemini 5 flight in 1965. The Combat collection followed in 1967. A majority stake in Glycine was sold to the Invicta Watch Group in 2016.
