Doxa Watches: A Legacy Beneath the Surface
For anyone who loves vintage dive watches or appreciates true horological innovation, Doxa is a name that resonates deeply. At Belmont Watches, we’re excited to share the story of a brand that has been pushing boundaries under the waves for over 130 years. From pioneering the first helium escape valve to creating that unmistakable orange dial, Doxa has made a splash in the world of professional diving watches—and continues to do so today.
Origins of Precision: Doxa’s Beginnings (1889–1950s)
The story of Doxa begins back in 1889 in Le Locle, Switzerland, when 21-year-old Georges Ducommun founded the brand with a passion for creating precise, high-quality timepieces. Fun fact: the name “Doxa” comes from the Greek word for “glory” or “reputation,” perfectly capturing the brand’s early ambition to earn its place among Swiss watchmaking greats.
Georges was no stranger to innovation. In 1907, he filed a patent for the groundbreaking “8-Day DOXA Caliber,” a watch movement that could run for eight days on a single wind. This technology was so trusted that it became standard equipment in Bugatti racing cars and set a benchmark in dashboard instruments for cars and airplanes. These early feats laid the foundation for Doxa’s future focus on durable, functional tool watches.
A Bold Splash: The Birth of the Sub 300 (1967)
The 1960s brought a wave of excitement to the diving community—and Doxa was ready to dive in. In 1967, after collaborating closely with professional divers and engineers (including the legendary Jacques Cousteau, via U.S. Divers), Doxa launched the game-changing Sub 300.
This wasn’t just another dive watch. It was packed with features made for real underwater adventure:
-
The famous bright orange dial, designed to be easy to read even in murky waters
-
A unidirectional no-decompression bezel to help divers safely track their dive times
-
The comfortable beads-of-rice bracelet, with an innovative dive extension clasp for quick adjustments
-
And most notably, the first-ever helium escape valve—a clever mechanism that protects the watch during deep saturation dives by releasing trapped helium gas.
Here’s a cool piece of history: Doxa actually beat Rolex to this helium valve breakthrough. During tough tests with Comex divers in November 1967, Doxa’s prototype valves worked flawlessly, a full month before Rolex’s similar system hit the market. Swiss newspapers even covered these experiments, highlighting how Doxa was leading the pack in dive watch innovation. This milestone firmly cements Doxa’s place in watchmaking history.

Special Forces and Funk: The Doxa Army
In the 1970s, Doxa created the Doxa Army—a tough, stealthy watch designed for elite Swiss Army divers. Its rugged design and unique khaki/black color combo make it a rare and highly collectible piece today.
Belmont Watches loves that Doxa has revived the Army line with modern updates and limited editions, keeping this cult favorite alive and kicking.
Weathering the Quartz Crisis and Cult Revival (1980s–2000s)
Like many Swiss brands, Doxa faced challenges during the quartz crisis, slowing production and fading a bit from the spotlight. But the passion never died.
Thanks to the internet and watch communities like Watchuseek, vintage Doxa watches started gaining cult status again in the early 2000s, especially the original orange Sub 300. Responding to this renewed interest, Doxa began releasing faithful reissues and updated models such as the Sub 300T Reissue and Sub 1200T, bringing the brand back to the forefront for collectors and divers.
