Catalogue description
Dealer description — Craft & Tailored
Longines is one of the oldest continuously operating watch manufacturers in the world, with roots dating back to 1832. Over that immense period of time, the brand has crafted some truly incredible—and incredibly accurate—timepieces. In fact, it's one of the reasons Longines is the official timekeeper of the Kentucky Derby, where accuracy is paramount. Whether it's a chronograph, diving watch, or a simple dress model, a Longines wristwatch never seems to disappoint. Longines' history is sprawling with an array of beautiful and functional watches, including beautiful sports watches, military-issued timepieces,and unique dress watches. The ref. 5150 is an iconic model from Longines, renowned for its elegant yet functional aesthetic, and for being both a military-issued and civilian model from the height of the Second World War. The classic navigator-style dial displays the time in both 12-hour and 24-hour scales in a very legible and organized fashion, for telling the time at a glance. The case, while measuring smaller is size at 32mm, is fashioned with long swooping lugs that extend the size of the watch to a more modern aesthetic. A stylish, yet still classically elegant timepiece ready for its next adventure.

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.
