When most people first discover glycine, they are startled that they had not heard of it before. Eugène Meylan, an engineer who manufactured timepieces, started the firm on May 20, 1914, in Bienne, Switzerland. Engineers typically tackle issues by refusing to accept the first suitable answer. Over a century of Swiss manufacturing, such patience paid off. Nonetheless, the brand is never discussed in the same breath as the names that attract waiting lists and high auction prices, and it exists quietly beyond the debate that frequently dominates watch collecting. That gap between quality and recognition is, honestly, one of the more interesting things about it. Glycine Watches occupy a strange and appealing space—over 110 years of genuine horological firsts, a factory still running in Biel, and prices that feel almost accidental given the pedigree behind them.
The Engineer Who Built Glycine Watches His Own Way
Meylan was an uncompromising watch engineer who strived for perfection and nothing else, and from day one Glycine burned its own trail by creating timepieces predicated upon a unique DNA always a bit outside of the mainstream. The early technical choices reflect that DNA. With precision and tenacity, Glycine made history with the first-ever baguette-shaped movement, patented in both 1923 and 1926. While bigger Swiss houses were building dress watches for wealthy Europeans, Meylan was experimenting with movement geometries nobody had tried. An important milestone came in 1931 with the introduction of the EMSA module, another quiet innovation that rarely gets mentioned when people talk about interwar Swiss watchmaking but should. The pattern was evident even before the brand had reached its twentieth anniversary: Glycine addressed challenges that intrigued Meylan, rather than focusing on issues that would simply serve as effective marketing material.
The Airman and the GMT Complication Nobody Knew Was Glycine’s First
The statement often leaves people momentarily speechless when they first hear it. Glycine was the first brand to produce a watch with a 24-hour rotating bezel—the Glycine Airman—in 1953, and production started from a conversation between a pilot, one of Glycine’s employees, and Samuel Glur. Not a focus group. Not an executive committee. A discussion with a pilot led to the creation of a solution that had not yet existed. The original Airman incorporated what would become its iconic features: a 24-hour rotating bezel, a 24-hour dial, and double crowns—each designed to address the specific challenges pilots faced when crossing time zones, eliminating confusion between AM and PM. This feature gained significant recognition in the watch community with the introduction of the Rolex GMT-Master a year later, in 1954.
Glycine got there first. Rolex gets the credit. That dynamic is frustrating if you care about these things, and probably irrelevant if you do not, but it explains a lot about why serious collectors keep circling back to this brand. The Airman also features a unique hacking system for the sweep-seconds hand to synchronize timing to the exact second, a detail that matters to anyone coordinating with a time standard rather than just checking how late they are for a meeting. Astronaut Charles “Pete” Conrad wore a Glycine Airman on his wrist throughout two missions, which is the kind of real-world endorsement that cannot be manufactured retroactively.
From the Cockpit to the Field: The Combat Line
In 1967, Glycine launched its second line specially crafted for land troopers, known as the Combat Watches, replicating the logic of the Airman for a different set of users with a different set of demands. Where the airman handled time zones and cockpit readability, the combat line handled mud, impact, and field conditions. Beyond its aviation legacy, Glycine built out a rugged combat collection backed by a history of innovation that included early automatic movements and vacuum-sealed cases for superior water resistance. These were not watches designed to look like military watches. They were watches genuinely utilized by the military, which sets them apart from brands that merely attempt to evoke that heritage without authentic backing.
The functional origin of Glycine Watches provides a credibility that is distinct from brands that merely add a bezel and Arabic numerals to label their products as field watches. The Combat line developed its design language gradually and authentically.
Swiss Made Without the Swiss Price Premium
This is likely where many first-time buyers of Glycine Watches feel pleasantly confused. Every Glycine watch carries the “Swiss Made” designation, a protected label that guarantees the movement is Swiss, cased in Switzerland, and undergoes final inspection by the manufacturer in Switzerland. Glycine has remained in Biel/Bienne for over a century, running its own factory throughout. That is not a sourcing arrangement or a marketing claim. It is a continuous manufacturing presence that predates most of the brands currently charging three times the price for the same designation. Glycine’s willingness to offer GMT complications and 24-hour dials at accessible price points sets it apart from most Swiss competitors in the same bracket, and the median price on the secondary market sits around $400—real Swiss automatic tool watches with provenance, not entry-level fashion pieces dressed up in aviation aesthetics.
A Design That Does Not Explain Itself
Glycine Watches tend to feature large, legible dials and reliable Swiss automatic movements, with a straightforward design and utilitarian focus that never really asks for your attention. The double-crown configuration on the Airman, the locking bezel, and the 24-hour dial—none of it is decorative. Every detail traces back to something a pilot or soldier once needed to actually work, which gives the design an internal logic that holds up over time better than anything trend-driven. In a market crowded with mass-produced timepieces, Glycine delivers quality pieces with a deep history at a price that makes them accessible rather than aspirational.
That is a rarer combination than it sounds. Most brands with this much history charge accordingly. Glycine largely does not.
Why It Still Matters
Through these innovations, Glycine established itself as a Swiss watchmaker committed to improving both functionality and user experience across more than a century of uninterrupted production. The brand did not build its reputation through advertising or celebrity association. It established its reputation in cockpits and on testing grounds by addressing the challenges that pilots and soldiers brought to Bienne, where they sought solutions. That history is baked into every current model in a way that is either important to you or irrelevant, depending on why you buy watches. For collectors and buyers interested in the origins of a design and its visual elements, Glycine Watches presents a compelling case that is difficult to dispute—not due to prestige, but because of their genuine history.
