The Cyma Dirty Dozen watch was part of a historic group of twelve military timepieces commissioned by the British Ministry of Defence during World War II. Produced to strict specifications under the W.W.W. (Watch, Wristlet, Waterproof) standard, the Cyma version stood out for its reliability and robust construction. Featuring a manual-wind movement, black dial, and luminous Arabic numerals, it was built for clarity and durability in combat. Today, it remains a highly collectible piece of wartime horology.

What's on Offer

We are delighted to offer for sale this superb example of the iconic 1945 Cyma Dirty Dozen military watch—an essential piece of British wartime horology.

The rich black dial remains wonderfully preserved, still boasting its bold Arabic numerals, clear outer minute track, and the recessed sub-seconds dial at 6 o’clock. The thick pencil-style hands retain their original lume, which has aged beautifully to a warm tone, complementing the vintage character of the watch. At the centre of the dial sits the instantly recognisable Broad Arrow—or ‘pheon’—marking it as the property of the British Ministry of Defence.

The case back also proudly bears the Broad Arrow alongside the correct military engravings that enthusiasts and collectors expect to see from an authentic Dirty Dozen issue. Housed in a robust stainless steel case and paired with a simple black NATO-style strap, this watch remains as functional as it is collectible.

In wonderful vintage condition throughout, this Cyma Dirty Dozen stands as a rare and historically significant piece of military watchmaking. A must-have for any serious collector or enthusiast of WWII-era timepieces.
