Glycine is a heritage Swiss tool-watch brand specializing in robust timepieces crafted for aviation, diving and active use. Known for its pioneering GMT and multi-time-zone models (most notably the Airman line), the brand combines bold functional design elements — such as 24-hour dials, rotating bezels, high water resistance — with Swiss mechanical craftsmanship, catering to pilots, divers and serious watch enthusiasts.

Since its founding in 1914, Glycine has sustained a design philosophy rooted in precision, practicality and innovation rather than decorative luxury. It embraces a retro-modern fusion: vintage pilot and diver watch cues (large cases, legible dials, GMT functions) with modern manufacturing and tool-watch durability. Its key products include the Airman series (GMT/aviation oriented) and the Combat / Sea Kraken series (diver-oriented). The target audience is the informed collector or active lifestyle buyer who values functional heritage, robust build quality and Swiss heritage without the ultra-luxury markup. Unique selling points for Glycine include its long and genuine Swiss origin (since 1914) with inventive modules such as the EMSA automatic winding system in the 1930s. Also, its iconic pilot’s watch (Airman) which has real aviation credentials and even ties to space missions.
