Dealer description — Vintage Watch Specialist

Grana WW2 Dirty Dozen Solider's Watch in Incredible Original Condition with Beautifully Aged Lume and Original Military Engravings. The Grana WW2 "Dirty Dozen" watch carries a significant place in military history and watchmaking excellence. During World War II, the British Ministry of Defence (MoD) recognized the need for a reliable, rugged, and easily readable wristwatch for its troops. This led to the commissioning of watches from twelve manufacturers, who collectively produced what would later be known as the "Dirty Dozen." The specifications set by the MoD were stringent: watches had to feature a black dial with Arabic numerals for easy legibility, a durable case resistant to various elements, luminous hands for visibility in low light conditions, and a robust movement capable of maintaining accurate timekeeping even in extreme situations. Highly sought after and with very few serious collectors amassing the full 12, collecting the complete set of Dirty Dozen Military watches has become a horological adventure for military enthusiasts and historians alike. The elusive Grana is the absolute holy grail for Dirty Dozen collectors, so few were produced in comparison with the other brands (roughly 1000-1500), they are particularly hard to find and particularly in good condition. What’s On Offer We are incredibly pleased to offer this superb (and scarce) Grana Dirty Dozen WW2 soldiers watch for sale. We have been lucky enough to procure a number of these sought-after watches over the last 12 years and we are always very sad to see them go, especially when they are in such superb condition as this one is. Just look at the beautiful rich black dial boasting all the hallmarks we would expect to see - bold Arabic numerals, a recessed sub-seconds dial at 6 o'clock, the military pheon (an arrow painted on the dial to denote the watch as the property of the MoD) and lumed hands and hour plots. The lume has aged to a beautiful pumpkin colour and is the jewel in the crown of this watch. To the caseback, you will note the watch's original military engravings which read WWW M18535 and the military pheon is present again. This watch has been incredibly well preserved, and given the rarity of the Grana Dirty Dozen, we don't expect it to be around for long, so don't sleep on this one, especially if this is the one you need to finish your set!

Historical context

Golden Age of Mechanical Watchmaking (1900 – 1945)

The wristwatch displaces the pocket watch; waterproof cases, self-winding and grand complications.

The wristwatch overtook the pocket watch. Military use in the First World War, aviation, water-resistant cases (1926), automatic winding (1923–31), rectangular Art Deco designs and early chronographs and calendars defined the period.

Atlas type guide

Military, pilot and travel watches

The wristwatch owes much of its adoption by men to warfare and aviation. Wristlets — small pocket watches soldered with lugs and worn on a strap — were used in colonial campaigns and became standard equipment in the First World War, with protective grilles over the crystal ('shrapnel guards'). Louis Cartier's Santos (1904), designed for the aviator Alberto Santos-Dumont, is often cited as an early purpose-made pilot's watch.

In the Second World War governments specified watches in detail: the German B-Uhr observation watches, the American A-11, and the British 'W.W.W.' (the 'Dirty Dozen' set of 1945). After the war, jet travel brought GMT and world-time watches, which show two or more time zones at once — Louis Cottier's world-time mechanism and the Rolex GMT-Master (1955) are examples.

What to look for

  • Military markings on the case back: broad arrow, issue numbers, 'W.W.W.', 'A.T.P.'
  • High-legibility black dials with luminous Arabic numerals; oversized crowns for gloved hands.
  • 24-hour hands and rotating 24-hour bezels or city rings on GMT/world-time watches.
  • Wire lugs on early wristlets converted from pocket watches.

Dating clues

  • Wire-lug wristlets: c. 1900–1925.
  • Military specifications of the Second World War: 1939–1945.
  • GMT and world-time wristwatches: mainly after 1950.
