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.
