During World War II, the UK asked 12 different brands (hence the name ‘Dirty Dozen’) to produce a military watch. All of them shall be stamped with the isncription W.W.W, which stands for ‘Watch. Wrist. Waterproof’. In total they produced around 145,000 units of these military watches, Cyma being one of the brands that produced the most (estimated 20,000 pieces) just behind Omega and Record.
Although these watches were mass produced for war, not many survived the 1970s, as companies destroyed them due to their radioactive Radium-226 lume. Therefore, finding one in good original condition is getting rarer each day.
Cyma produced the largest watch of the dozen, casing their caliber 234 on a 38mm stainless steel case -excluding crown-. We must note that Cyma produced this watch in two variants, one with the lume on top of the hands and one, like this example, with the lume being inside the metal borders of them. Due to the nature of this lume, we believe having the latter variant will prove the test of time in a more effective way.
