Founded in 1862, Cyma established itself as one of Switzerland's most respected watchmakers, building a reputation for precision engineering and robust mechanical movements. During the Second World War, Cyma became one of the twelve manufacturers chosen to supply the British Ministry of Defence with the legendary WWW ("Watch, Wristlet, Waterproof") military watches. Today, the Cyma Dirty Dozen is considered one of the most desirable models of the collection, admired for its larger case size, reliable in-house movement and unmistakable military styling. What's on Offer This original and recently serviced Cyma WWW Dirty Dozen is a highly collectable British military wristwatch dating to approximately 1944. Manufactured for the Ministry of Defence during the Second World War, it retains all the hallmarks that have made the Dirty Dozen series so sought-after by collectors, including the iconic black military dial, broad arrow marking, and robust stainless-steel waterproof case. The dial displays an attractive aged patina, with the original luminous numerals, plots and hands mellowing naturally over eight decades while preserving the authentic character expected of an original military-issued timepiece. The clearly engraved WWW military caseback, complete with broad arrow and issue numbers, further confirms its military provenance. Inside beats the dependable Cyma Calibre 234 manual-wind movement with 15 jewels and an impressive 44-hour power reserve. Known for its durability and smooth operation, the Calibre 234 was specifically chosen for military service where reliability was paramount. Measuring a generous 38mm across, the Cyma is one of the larger Dirty Dozen watches, giving it excellent wrist presence while remaining faithful to its original military design. Paired with a sand NATO strap, this is a superb example of one of Britain's most iconic military watches and an essential addition to any serious military or vintage watch collection.
