🕰️ Doxa Company History

Doxa was founded in 1889 by Georges Ducommun in Le Locle, Switzerland — one of the most important watchmaking towns in the world, nestled in the Jura mountains. The name Doxa comes from the Greek word for “glory” — a fitting name for a brand that would go on to produce some of the most celebrated dive watches ever made.

From its earliest years, Doxa built a reputation for producing accurate, reliable, and affordable timepieces. The company supplied movements to other brands and established itself as a respected mid-tier Swiss manufacturer. By the early 20th century, Doxa had expanded its range to include pocket watches, military watches, and early wristwatches.

The pivotal moment in Doxa’s history came in the 1960s, when the brand turned its full attention to professional diving watches. The underwater world was opening up — driven by Jacques Cousteau’s expeditions, the growth of recreational scuba diving, and demand from commercial and military divers. Doxa was perfectly positioned to meet that demand.

In 1967, Doxa introduced the SUB 300 — a watch that would define the brand for generations. It was the first commercially available diver’s watch to feature a helium escape valve, allowing saturation divers to safely decompress without damaging their watches. It also introduced the now-iconic orange “No Decompression” dial — a functional tool that displayed decompression stop times directly on the dial.

The SUB 300 was not just a technical achievement — it was a design statement. Its bold colors, legible dial, and robust construction made it instantly recognizable. It became the watch of choice for professional divers worldwide and cemented Doxa’s place in horological history.

🗓️ Doxa Brand Timeline

🤿 Jacques Cousteau & the Doxa SUB 300

No story about Doxa is complete without Jacques Cousteau. In 1969, Doxa entered into a partnership with Cousteau’s Aqua-Lung company — the leading distributor of scuba diving equipment in the United States. The SUB 300 was sold through Aqua-Lung dealers and became the official watch of Cousteau’s diving team.

Cousteau’s team wore the Doxa SUB 300 during their famous underwater expeditions, including the Conshelf underwater habitat projects. The watch appeared in Cousteau’s films and television programs, giving Doxa extraordinary global exposure at the height of the diving boom.

The Cousteau connection gave Doxa something no marketing campaign could buy: genuine credibility with professional divers. The SUB 300 was not a watch designed for the wrist of a desk worker — it was a tool trusted by the world’s most famous underwater explorer.

🎨 Doxa Dial Colors — What They Mean

One of Doxa’s most distinctive features is its use of bold dial colors — each with a specific functional meaning for divers. The original SUB 300 was offered in four colors:

⚙️ Movements Used by Doxa

Doxa used a range of Swiss ébauches across their lineup. The movement inside a vintage Doxa is an important factor in both authenticity verification and collector value:

• ETA 2472 / 2783 — The most common movement in vintage SUB 300 watches. A reliable 17-jewel automatic with date. Well-supported with widely available service parts.
• ETA 2824-2 — Used in later SUB 300 and SUB 200 models. One of the most robust and accurate Swiss automatic movements ever produced.
• AS (A. Schild) Ébauches — Used in some Doxa dress and sport models from the 1960s–70s. Reliable and serviceable.
• ETA 2836-2 — Used in modern revival SUB models. Day-date complication, high accuracy.

🛒 Buying a Vintage Doxa — What to Look For

• Confirm the reference — SUB 300, SUB 300T, and SUB 600T are the most collectible. Check the case back for the reference number.
• Check the dial — original Doxa dials are printed with crisp text and no fading. The “No Decompression” scale on orange dials should be fully legible. Avoid refinished dials.
• Inspect the bezel — the unidirectional rotating bezel should click positively and show appropriate wear. Replacement bezels are common — verify originality.
• Check the helium escape valve — present on SUB 300 and above. Should be original and functional. Replacements reduce value.
• Verify the crown — Doxa crowns are screw-down on dive models. Original crowns with correct Doxa logo are important.
• Confirm it runs — a running Doxa is worth significantly more than a non-runner. Budget for a service if needed.
• Check the case — avoid heavily polished cases. Original brushed and polished surfaces indicate an unrestored watch.
• Look for Aqua-Lung branding — SUB 300 watches distributed through Aqua-Lung have “Aqua-Lung” printed on the dial. These command a premium.
