Eugène Meylan founded Glycine in Biel in 1914, initially making small precision movements for elegant ladies' watches. The brand's immortality came in 1953 with the Airman: a purpose built pilot's watch with a 24 hour dial and rotating bezel, designed after a conversation with an airline pilot about tracking multiple time zones. It became beloved equipment among aviators, famously worn by American pilots during the Vietnam era.
The Airman's cult never died, sustaining Glycine through the quartz decades alongside the value oriented Combat line. In 2016 the Invicta group acquired Glycine, a move enthusiasts feared would cheapen the name. Prices dropped and distribution widened, but the Airman formula survived largely intact.
The Airman remains one of very few true 24 hour dial watches in serial production, with the Airman No. 1 reissuing the 1953 original faithfully. Purist versions run a single 24 hour hand format, while Double Twelve variants offer conventional reading. Movements are Swiss automatics, and the crown locking bezel system continues the original patent lineage.
Prices run roughly 400 to 1,500 dollars, dramatically lower than before the acquisition.

Glycine is a one icon brand, and that icon is genuinely great: the Airman remains aviation watchmaking's most distinctive answer to time zones. Invicta ownership cost prestige but made the history absurdly affordable. Buy the Airman No. 1 or SST, learn the 24 hour dial, and enjoy a real tool watch story for used Seiko money.
