Catalogue description
Dealer description — Oliver & Clarke
Watches still played a critical role in military service in the 1970s. As a result of the need for a more robust dive watch tailored to the military's needs, the United States Department of Defense issued the MIL-W-50717 standard, which put forth a more robust list of required specifications, more so than any prior contract. There were many options for lower level officers and platoons when it came to timepieces, but for the best of the best including the renowned Navy Seals, the Benrus Type I and Type II were the best option. The Type I was the earliest version and far more rare, making this piece one of only a handful ever produced. Benrus made these pieces exclusively for the military from 1972 to 1980, with this particular example dating to circa 1979 ( April of 1979 to be exact ). The 42mm case is unpolished and seemingly untouched for many years. It's case retains its original sandblasted satin finish, fixed-bar lugs, and crisp printing on the caseback, denoting its military provenance and unique serial number. And though complete acceptable and normal, most examples of Type I and Type IIs possess replacement crowns, while this example retains its original. Even the crystal is likely original to the watch, exhibiting crazing and some fracturing as many of these do. The bi-directional rotating bezel matches the condition of the case and retains its black acrylic 12-hr insert — also showing wear consistent with the rest of the piece. The matte black 'sterile' dial within is beautifully preserved with no visible imperfections or wear, and shows even color across the luminous elements. The white-painted handset shows matching luminous material, with a slightly more patinated seconds hand. Due to their limited production, active use during military trials, decommissioning, and flat out loss, not all that many of these pieces survive today — particularly in this kind of condition. We are pleased to offer this Type I up for its next tour of duty, and invite you to strap a real piece of history to your wrist.
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
Military, pilot and travel watches
The wristwatch owes much of its adoption by men to warfare and aviation. Wristlets — small pocket watches soldered with lugs and worn on a strap — were used in colonial campaigns and became standard equipment in the First World War, with protective grilles over the crystal ('shrapnel guards'). Louis Cartier's Santos (1904), designed for the aviator Alberto Santos-Dumont, is often cited as an early purpose-made pilot's watch.
In the Second World War governments specified watches in detail: the German B-Uhr observation watches, the American A-11, and the British 'W.W.W.' (the 'Dirty Dozen' set of 1945). After the war, jet travel brought GMT and world-time watches, which show two or more time zones at once — Louis Cottier's world-time mechanism and the Rolex GMT-Master (1955) are examples.
What to look for
- Military markings on the case back: broad arrow, issue numbers, 'W.W.W.', 'A.T.P.'
- High-legibility black dials with luminous Arabic numerals; oversized crowns for gloved hands.
- 24-hour hands and rotating 24-hour bezels or city rings on GMT/world-time watches.
- Wire lugs on early wristlets converted from pocket watches.
Dating clues
- Wire-lug wristlets: c. 1900–1925.
- Military specifications of the Second World War: 1939–1945.
- GMT and world-time wristwatches: mainly after 1950.
