Catalogue description
Dealer description — Bulang & Sons
As you might know by now, we have a deep love for Tudor Snowflake Submariners—but military-issued examples? Those are on another level. Over the years, we’ve had the privilege of sourcing and selling some of the finest first-owner pieces, and we’re excited to offer another exceptional example. At hand is a Tudor Submariner ref. 94010, issued to the Marine Nationale (French Navy) in 1980. The case remains in excellent condition, complemented by a beautifully aged faded blue bezel insert, showing just the right amount of wear from its time in service. The lume pip has been refilled in the past, a common sight on these hard-worn military pieces. The caseback proudly bears the legendary "MN 80" engraving—a defining feature of these historically significant watches. The matte blue dial is in excellent shape, with its lume developing a warm, soft yellow patina. The Snowflake hands—a signature Tudor design—have been stabilized in the past, ensuring their preservation, as is often seen on military-issued examples. The watch is fitted on a Bulang & Sons single-pass strap, just as French Navy divers would have worn it. Beyond its military pedigree, this piece carries additional provenance: it is recorded in the official ledgers of Yves Pastre, a watchmaker for the Marine Nationale. Pastre meticulously documented the timepieces he serviced for the Toulon Navy Stores ( Approvisionnement de la Flotte, or AF ), noting the maker, model, and serial number. A copy of the ledger page mentioning this exact watch will be included in the sale—a rare piece of documentation that further cements this watch’s historical importance. Fully serviced by our watchmaker, this legendary French Navy-issued Tudor Sub is ready for its next mission. Specifications: - Tudor Submariner ref. 94010 - 40mm stainless steel case - Marine Nationale-issued "MN80" engraving on caseback - Original matte blue dial with warm patina - Original faded blue bezel insert - Serial 93xxxx, dating to 1980 - Documented in the Marine Nationale watchmaker’s ledger (copy included) - Bulang & Sons single-pass fabric strap - Fully serviced by our watchmaker
Historical context
Quartz Revolution (1969 – 1990)
Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.
Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

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.
