Lemania is one of Switzerland’s most respected movement makers, founded in 1884 and renowned for precision chronographs and military timepieces. During the Second World War, Lemania was one of the twelve manufacturers selected by the British Ministry of Defence to produce the now-famous “Dirty Dozen” watches for military use. Built to strict specifications, these watches prioritised durability, legibility and reliability in the field, cementing Lemania’s place in British military watch history.

What's on Offer

This Lemania Dirty Dozen from c.1945 is a superb example of one of the most collectible British military watches ever produced. Housed in a chrome-topped case, it shows honest signs of service wear, adding to its authenticity and character rather than detracting from it.

IThe black radium dial has aged beautifully, with warm patina across the lume plots and hands, giving it that unmistakable vintage military look. Clear Arabic numerals, a precise minute track and recessed sub-seconds at 6 o’clock ensure excellent legibility — exactly as intended for wartime use.

Powered by the reliable Lemania Calibre 27A, recently serviced by our watchmaker, the watch delivers robust manual-wind performance, built to meet strict Ministry of Defence specifications.

A particularly desirable feature here is the presence of matching lug numbers, a detail that collectors value highly as it reinforces originality and integrity. Paired with its military engravings and classic field-watch proportions, this is a true piece of history — functional, honest and increasingly hard to find in such complete form.
