Catalogue description

Dealer description — Craft & Tailored

In the 1940s CYMA was one of the ‘Dirty Dozen’, which was a selection of 12 watch brands worn by WWII British soldiers. The 'Dirty Dozen' brands were commissioned by the British Ministry of Defense, which needed as many watches as possible produced for the British soldiers. Manufacturing capacity at the time allowed for roughly 145,000 watches to be produced. The arrow seen on the dial, which is regularly seen on military watches, marks the watch as "crown property"; the British monarch's sovereign public estate, which was considered neither government property nor part of the monarch's private estate. Although manufactured by a dozen companies (known as the "Dirty Dozen" by military watch collectors), CYMA's models are especially sought-after, as CYMA utilized high-quality steel for their version of the MOD spec watch, despite the steel shortage caused by the war efforts of the time. The other brands had to make their watch cases from much more inferior metals, meaning many of the watches offered by the other brands of the "dirty dozen" haven't held up in the following decades.

Historical context

Golden Age of Mechanical Watchmaking (1900 – 1945)

The wristwatch displaces the pocket watch; waterproof cases, self-winding and grand complications.

The wristwatch overtook the pocket watch. Military use in the First World War, aviation, water-resistant cases (1926), automatic winding (1923–31), rectangular Art Deco designs and early chronographs and calendars defined the period.

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.
