The Dirty Dozen Watches: The Twelve W.W.W. of World War II
There is no shared name on their dials. No single maker’s emblem. And yet the twelve watches collectors know as the « Dirty Dozen » form one of the most coherent — and most admired — sets in watchmaking history. Born of wartime urgency and delivered in the closing months of the Second World War, they unite manufactures as different as Jaeger-LeCoultre, IWC, Omega and Britain’s own Vertex under a single specification.
W.W.W.: Watch, Wrist, Waterproof
In 1944, with the war raging on every front, the British War Office issued an exceptional tender. The army needed wristwatches that were reliable, legible in all conditions and water-resistant — a requirement that had become critical since the amphibious landings. The selected watches received the official W.W.W. marking, which simply stands for Watch, Wrist, Waterproof.
Twelve Swiss manufactures — and a single British one — answered the call and were retained. Their names have become legendary: Buren, Cyma, Eterna, Grana, Jaeger-LeCoultre, Lemania, Longines, IWC, Omega, Record, Timor and Vertex. The last of these, based in Plaistow, England, remains to this day the only British maker in the series — a rare distinction in a field dominated by Swiss watchmaking.
A rigorous military specification
Every watch in the programme shared a strictly identical specification, laid down by the British military authorities:
- Black dial with Arabic numerals
- Small seconds at 6 o’clock
- Railway-style minute track
- Luminous hands and indexes
- Hand-wound mechanical movement, 11.75 to 13 lignes, with a minimum of 15 jewels
- Shock-resistant case, shatter-proof mineral crystal
- Waterproof crown, operable with gloves
On the case back, the markings are unambiguous: the initials W.W.W., the broad arrow (the mark of British state property, inherited from the Admiralty), and a military serial number made up of a letter followed by five digits. These markings allow today’s collectors to authenticate the pieces with near-absolute certainty.
A concentrated production, a lasting impact
The watches were produced within an extremely short window — between 1944 and 1945. The end of the war caused orders to collapse. In total, an estimated 150,000 examples were delivered, spread very unevenly across the twelve manufactures. Some brands, such as Longines and Omega, already had the industrial infrastructure to supply large volumes; others, such as Grana and Timor, remain far rarer and are particularly sought-after today.
None of the watches carried the « Dirty Dozen » nickname at the time. It was adopted retrospectively by collectors, in reference to the American war film The Dirty Dozen (1967).
Why do the Dirty Dozen fascinate collectors so much?
Their appeal comes from a unique combination of factors. First, legibility: the black dial with luminous Arabic numerals is absolutely clear, even in total darkness. It set the standard that inspired much of the aesthetic of contemporary field watches.
Then, their diversity: comparing a Jaeger-LeCoultre W.W.W. with an IWC W.W.W. side by side means watching two first-rank manufactures interpret an identical specification in different ways — in movement finishing, case proportions, dial typography.
Finally, their growing rarity: few were made, fewer have survived in good condition, and collector demand has kept rising since the 1980s. A well-preserved Dirty Dozen with intact military markings now trades between €1,500 and €15,000 depending on brand and condition — with Lemania, Grana and Vertex the rarest of all.
More than seventy years after they were made, these twelve watches still tell an industrial, human and horological story on the wrist. A story no other series can match.
