Catalogue description

Dealer description — Craft & Tailored

The Benrus Type-1 Class A is built like a tank and for a good reason. In the ’70s, the American military needed a dive watch made to a particular specification outlining their needs for a diving watch under military specification MIL-W-50717. Benrus answered the military's call and came up with the Benrus Type-1, and later the Type-2. Being that this was a high-quality piece of equipment built for a specific need, the United States Army as well as the United States Navy, issued these watches to only the most elite military units. Both the U.S. Army's Rangers and Green Berets as well as the U.S. Navy Seals and UDT (Underwater Demolition Team) divers were issued the Benrus Type-1 and Type-2 wristwatches. The case of the Benrus Type-1 is referred to as a "monocoque" case, rather than the more ordinarily known "monobloc" style case. "Monocoque" relates to the construction of the case as a sort of vessel that holds the dial, hands, and movement while the bezel envelops the domed crystal, ultimately allowing this watch to be taken apart through the top or face of the watch instead of through the back like most dive watches. This unique case design adds to the durability and ruggedness of the watch. The Benrus Type-1 is equipped with fixed spring bars like other issued dive watches for added security and one less failure point, a sterile dial meaning there is no logo or branding, and is bead blasted for an anti-reflective finish required by the men who wore them. The case back is stamped with the mil-spec number (MIL-W-50717), the NSN Number as well as the actual military inventory number used to check in and check out service equipment similar to what you would find on a firearm and or any other issued technical piece of equipment. The Benrus Military Navigation and Submersible Wristwatches have exponentially grown in popularity amongst collectors in recent years. The rugged no-nonsense design is unmistakable and has a perfect balance of beauty and utilitarian design. Though both the Benrus Type-1 and Type-2 watches have become difficult to source, the Type-1 is the rarer and more collectible of the two watches produced. The Type-1 Benrus was quickly phased out for the higher production Type-2, making for a much smaller production pool remaining intact today. We are extremely excited and very proud to be offering this exceptional Benrus Type-1 that is not only an impressive timepiece on its own, but also retains its original factory Benrus box, instruction pamphlet, as well as its original strap. This time capsule is not only an incredible set but a collectible piece of horological history.

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

Wristwatches

Bracelet watches were worn by women from the early nineteenth century — Breguet made one for Caroline Murat, Queen of Naples, in 1810–12 — but the wristwatch only became a man's instrument with military use and aviation in the early twentieth century. Between the World Wars it overtook the pocket watch; the 1920s and 1930s brought rectangular Art Deco cases, water-resistant cases and the first automatic winding systems.

After 1945 the wristwatch became a carrier of identity — dress watches, sports and dive watches, chronographs, calendars — produced by Swiss, American, Japanese, German, Soviet and Chinese industries. The quartz revolution after 1969 and the mechanical renaissance since the 1990s, including the rise of independent watchmakers, complete the story.

What to look for

  • The reference number (between the lugs or inside the case back) and serial number, the starting point for dating.
  • The calibre: its maker and number are often stamped under the dial or on the bridge.
  • Originality of dial, hands and crown — refinished ('redial') dials are common.
  • Case material marks: 18K/750, 14K/585, stainless steel, gold-filled, plated.

Dating clues

  • Wire-lug cases: before c. 1925.
  • Water-resistant screw-down cases: from 1926.
  • Quartz movements: from 1969; sapphire crystals widespread after c. 1980.
