Here we have a good example of a WW2 British Military Issued Cyma ‘Dirty Dozen’ WWW watch. It has a large 38mm case, which is full stainless steel, with the broad dished bezel design. It has a polished bezel finish, with light brushing to the top of the lugs and the sides of the case. It also has the original broad crown to the right. The dial is originally black but has aged to a green/brown tone with exposure to sunlight and the effects of the Radium luminous plots. It still has the later MOD applied replacement luminous plots, with the bold white Arabic numerals. The railroad track sits around the outside, with the sunken sub-second dial above 6. The dial is signed ‘Cyma’ below 12, with the Broad arrow.
The index hands indicate the time and have the matching MOD luminous. The rear is signed with broad arrow and ‘W.W.W.’ marking, with the two serial numbers. It is also stamped inside. It has the original movement cover, which can often be missing. Inside is the manual wind Cyma calibre 234 movement. It has been recently serviced and is keeping time to within +/- 10 seconds a day.
The watch has an estimated production of around 20,000 examples. It is a favourite amongst collectors due to it having the 2nd largest of all the Dirty Dozen cases and the full steel construction. It was one of the higher production watches, with approximately 20,000 manufactured.
No two dirty dozen watches are the same. The sizes vary, ranging from 35mm (Vertex) to 38mm (Longines). The handsets also vary across the watches, with the Cyma having index style hands. The Cyma also has a recognisable numeral font with the flat topped 4. The sub-second dial has 5 second dash markers, with no arabic graduations.
History of Dirty Dozen
They are affectionately known by collectors as the Dirty Dozen, after the 1960s film, which depicted the misadventures of 12 fictional soldiers during WW2. It is also a neat reference to the 12 different examples.
During the 1940s the MOD in Britain required watches to be issued to the military during WW2. They needed to be reliable, accurate and durable. The specification required that they have a black dial, clear Arabic numerals, luminous hour/minute hands, luminous plots, a railroad minute track, a sub-second dial and a shatterproof crystal.
They invited Swiss brands to build watches to these specific criteria. 12 brands were chosen. These were; Buren, Cyma, Eterna, Grana, jaeger LeCoultre, Lemania, Longines, IWC, Omega, Record, Timor and Vertex.
They were delivered in 1944 and into 1945, which meant that many of the watches may not have seen action. Comparatively, ATP issue watches were worn throughout the second world war. Despite this, the WWW watches are desirable and widely collected due to the larger sizing of the cases, the black dials and for some examples, the full Stainless cases.
They were issued under the classification of ‘General Service’, but they were issued to special units, including radio operators and artillery staff members.
The watch has the Broad Arrow (pheon) which indicates that it was British Government issue property. The watches carry the W.W.W. stamp to the rear, which was a code established by the British Army. It simply stood for ‘Watch.Wrist.Waterproof.’ Two serial numbers were engraved, one being the manufacturers and the second with the letter, from the military store.
