Catalogue description
Dealer description — Craft & Tailored
Its sharply faceted 37mm case features a hinged upper lug and a distinctive 12 o’clock crown with an integrated guard — a radical yet practical design to prevent wrist interference. A bold, oversized acrylic bezel with luminous inserts surrounds a deep black dial with circular lume plots and a dramatic arrow-shaped minutes hand. Though eccentric in design, the thin profile and articulated lug make it surprisingly wearable, with a unique wrist presence that balances function and flair. Though largely unknown outside professional diving circles, the Triton remains one of the most original and purpose-driven dive watches of its era. Its obscurity and technical charm have earned it cult status among collectors, and in 2023, the design was reimagined and revived in a modern reissue — further cementing its place in the pantheon of serious dive instruments. This particular watch — the first we’ve ever had the pleasure to offer, is a completely original and particularly well-preserved example from the early 1960s. A wearable representation of times past, when design, ingenuity, and utility constituted the watch industry and birthed the icons or avante-garde creations we celebrate today. SPECS Stock # TRNSPIRO Brand Triton Style Spirotechnique Diver Model N/A Serial 47XXXX Size Men's Material Stainless Steel Dial Matte Black Millimeters 38 Strap Black Rubber Tropic Strap CASE & BRACELET The excellent stainless steel case retains crisp factory chamfers, finishing, and geometry throughout. The hinged top lugs articulate to fit the wearer's wrist more ergonomically and remain in full operational condition. The large winding crown located at 12 o'clock on the case remains original to the watch. The original bezel remains in impressive vintage condition, showing honest signs of light wear with no cracks present, though when inspected under UV light the "2" of the "20" marker is missing most of its lume while the rest of the markers display no degradation. The case back retains its factory medallion at the center in crisp overall condition, with light tool marks present around the edges. The watch comes supplied on a 2pc tropic rubber strap. DIAL & HANDS The original glossy black dial remains in a wonderful vintage condition that is seemingly flawless to the naked eye, though the dial does present some minor elements of age and marks that are only visible under direct light and magnification. Under UV light inspection, the lumed markers around the dial exhibit consistent degradation but all retain a layer of the original luminous material. The original gilt hands have developed a deep green coloration to the lume, when inspected under UV light the hour hand exhibits some superficial cracking in the lume and remains stable while the minute and second hands exhibit no degradation. The red date wheel adds a subtle touch of color and vintage flair to complete the watch. ACCESSORIES None. The watch is functioning and keeping time perfectly, previous service history is unknown.
Historical context
Modern Mechanical Horology (1945 – 1969)
Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.
The classic era of the mechanical wristwatch: dive watches, chronographs for motor racing and space flight, GMT watches for jet travel, slim dress watches, automatic calendars, and the rise of Japanese manufacturers alongside Swiss, American, German and Soviet industries.

Atlas type guide
Dive and water-resistant watches
Keeping water and dust out of a wristwatch was a long-standing challenge. Rolex's screw-down Oyster case (1926) and Omega's Marine (1932) were landmarks; in the early 1950s Blancpain's Fifty Fathoms and Rolex's Submariner defined the professional dive watch with rotating bezels for timing dives, luminous dials and high water resistance. The ISO 6425 standard (1982) later codified what a 'diver's watch' must do.
Dive watches became icons of post-war design and exploration, and their evolution — helium escape valves, ceramic bezels, saturation-diving depth ratings — records the history of underwater work.
What to look for
- Unidirectional or bidirectional rotating bezel with minute markings.
- Screw-down crown and case back; depth rating printed on the dial.
- Luminous hands and markers (radium before c. 1960, tritium c. 1960–1998, then Super-LumiNova).
- Reference numbers on the case between the lugs or inside the back.
Dating clues
- Screw-down Oyster cases: from 1926.
- Professional dive watches: from 1953.
- Tritium 'T' marks on dials: c. 1960–1998.
