Whenever the subject of aviation comes up, the name of Glycine is mentioned as one of the pioneers of watchmaking for pilots and frequent travellers. Beginning in 1953, Glycine started production of the Airman, a watch that became legendary for introducing multiple time-zone watches to the market. Since then, Glycine has developed an unbroken chain of aviation watches, ranging from successively more complex world timers to unique collectors items. In 2002 Glycine reached a new pinnacle when it launched a genuine innovation: The Airman 7, featuring three mechanical movements simultaneously displaying the time in four time zones. In 2014 Glycine launched the Airman Air-fighter another genuine milestone in the history of pilot chronographs.
