In the world of horology, military watches occupy a unique and revered space. Combining durability, precision, and functionality, these timepieces are built to endure the harshest conditions while maintaining accuracy, making them indispensable to soldiers. Among the most collectible and celebrated military watches are a series of twelve wristwatches.
In 1945, the British Ministry of Defence commissioned the production of a new military watch. The specifications were clear: black dials with luminous Arabic numerals, luminous hands, and a railroad minute track to enhance readability, especially in combat or low-light conditions. Additionally, the watches had to feature a shatterproof crystal, a durable stainless steel case, and a robust, hand-wound movement that could withstand harsh environments.
Given that most British watchmakers were preoccupied with making other essential wartime equipment, they signed up 12 different Swiss companies to help. These companies were:
- Buren
- Cyma
- Eterna
- Grana
- Jaeger-LeCoultre
- Lemania
- Longines
- IWC
- Omega
- Record
- Timor
- Vertex
Some of these companies produced up to 25,000 pieces, while smaller companies could only commit to 5,000. The scarcity of the smaller brands is what makes collecting the ‘Dirty Dozen’ such a challenging goal.
On the back of each watch were the letters WWW, standing for wristwatch waterproof. There were also two serial numbers, one for military use and the other for civilian. In some cases, the watches were sold for use by other militaries, where they received a third serial number.
The primary role of a tool watch, especially in military contexts, is to provide dependable performance under extreme conditions. Military watches like the Dirty Dozen weren’t designed to be luxury items; they were critical instruments for soldiers, ensuring accurate timekeeping in situations where failure could mean life or death. Whether coordinating maneuvers or timing airstrikes, soldiers needed a tool that could function flawlessly in adverse environments—rain, mud, extreme temperatures, and shock.
Other interesting military watches to look out for:
- The ATP (Army Trade Pattern): These were the British-issued watch prior to the ‘Dirty Dozen’. They have similar design cues to the ‘Dirty Dozen, but have a cream-coloured dial. Since the ‘Dirty Dozen’ have stolen the limelight, these watches have become the more affordable military collectors watch.
- The A-11 (U.S. Military Watch – WWII): Known as “the watch that won the war,” the A-11 was produced for the U.S. military during World War II by Bulova, Elgin, and Waltham. With a simple, utilitarian design similar to the Dirty Dozen, the A-11 was highly legible and reliable. Its robust movement made it a favorite among American soldiers and Allied forces. The A-11 remains a favorite among collectors of military watches, particularly for those interested in World War II-era timepieces.
- The German B-Uhr (Flieger): The B-Uhr, or “Flieger,” was designed for Luftwaffe pilots during WWII. With an oversized case (up to 55mm), highly legible dial, and distinctive triangle marker at 12 o’clock, these watches were created to be read quickly in the cockpit. Brands like Lange & Söhne, IWC, and Stowa produced these iconic pieces, which have become staples in military and aviation watch collecting. While they differ in size and function from the Dirty Dozen, they share the same core values of precision and durability.
- The Rolex MilSub (Submariner): The Rolex MilSub is perhaps the most coveted of all military watches. Issued to the British Royal Navy, this variant of the Rolex Submariner was adapted for military use with features like fixed spring bars, a bezel with minute graduations, and sword-shaped hands for better readability. The MilSub’s blend of Rolex’s legendary craftsmanship with military specifications has made it one of the most desirable—and valuable—watches among collectors.
The Dirty Dozen watches are not only relics of a pivotal moment in history but also epitomize what a great military tool watch should be: tough, accurate, and purposeful. For collectors, these timepieces represent a rare blend of historical significance, craftsmanship, and utility. Their minimalist design, born out of necessity, has become a timeless aesthetic appreciated by both collectors and those who value the functionality of a well-made tool watch.
