Glycine was founded in 1914 in Biel/Bienne by Charles Perret, Georges Flury and Fernand Engel, and its best-known watch is the Airman, which the brand says it designed in 1953 at the request of the British pilot Chat Brown and patented the same year. It paired a 24-hour dial with a lockable rotating hour bezel so a pilot could read two time zones at a glance, and an Airman went to space on Pete Conrad's suit for Gemini 5 in 1965. The Combat line followed in 1967 on an EPSA compressor case. aBlogtoWatch reported in 2016 that DKSH, which had quietly bought a majority stake two years earlier, sold it to Invicta Watch Group, a pairing it called worrying for longtime Glycine fans. Bronze now runs across the Combat Sub divers and into the Airman GMT, on Sellita movements. Glycine's own product pages call the case material simply bronze, while its dealer Gnomon lists the alloy as CuSn8 marine bronze.

What the catalog shows about Glycine

The range is narrow: 64 percent of what the guide holds from it is dive watches. It states a standard alloy grade on none of its titanium references, against 45 percent across the catalog, so the alloy behind its titanium is rarely if ever named. All of its references here are mechanical. It publishes a case weight for none of its references, so the guide carries no measured weight for the brand.

Derived from the 11 references below, recomputed on every update, and printed only where a measurement stands apart from the rest of the catalog.
