The Jaeger LeCoultre 6B/159 is one of the most evocative military watches of the Second World War. Produced for the British Royal Air Force, these watches were not designed as luxury objects. They were designed as working instruments, issued to pilots, navigators and military personnel who needed clear, reliable timekeeping in a period where accuracy could genuinely matter.
The 6B/159 designation refers to the British military specification used for these RAF wristwatches. During the war, the military required standardised watches that could be supplied by different manufacturers but still meet the same practical demands. Legibility, durability and reliable movement quality mattered far more than decoration. That is exactly why these watches look the way they do: simple Arabic numerals, clear hands, a clean minute track and a case built for function rather than luxury.
This 1943 example is signed LeCoultre on the dial and is powered by the Jaeger LeCoultre calibre 470 manual wind movement. The case back carries the 6B/159 military marking, the broad arrow military property mark and the individual issue number, all of which give the watch its character and provenance.
What makes these watches so collectible today is the honesty of their purpose. They were made for wartime use, often with chrome plated brass cases due to the material restrictions of the period. They were tools first and watches second. Many were heavily worn, damaged, recased or modified over time, so finding an example that still carries this much visible originality and military identity is always interesting.
The dial has aged to a warm ecru tone with bold black Arabic numerals and blued hands, giving the watch a fantastic period look. It is not perfect, nor should it be. The charm is in the age, the wear, the military markings and the fact that this watch has survived from 1943 with such a clear connection to wartime RAF history.
This is not just a vintage Jaeger LeCoultre. It is a small piece of military watch history.

A Word on Condition
This Jaeger LeCoultre 6B/159 presents exactly how a true wartime military watch should. The case shows honest wear throughout, with visible age to the chrome plating, particularly around the bezel, lugs and case edges. This is very much part of the appeal. These watches were issued as tools, worn in service and built for function rather than preservation.
The ecru dial has aged beautifully, with an even warmth that gives the watch real character. The black Arabic numerals remain strong and highly legible, while the blued hands have developed the sort of tone and age that collectors look for in military watches of this period.
The case back is especially important. The 6B/159 marking, broad arrow and issue number give the watch the military provenance that separates these from ordinary civilian watches of the same era.
Overall, this is an honest and highly characterful example of a Jaeger LeCoultre RAF military watch from 1943.
Accessories / The Set
This watch is sold as watch only, which is typical for military and vintage timepieces. We place greater value on condition, originality, correct markings and overall integrity than on whether a box or papers happen to be present.
With military watches in particular, the case back markings are often more meaningful than conventional paperwork. They tell you what the watch was, who it was made for and the specification it was issued under.
All purchases are supplied with bespoke Watts On Watches packaging and full purchase documentation.
Why Buy This Watch
Collectors are drawn to the Jaeger LeCoultre 6B/159 because it sits at the meeting point of military history, functional design and serious watchmaking. It has none of the unnecessary decoration of a luxury watch, yet it carries far more story than many watches made purely for prestige.
The attraction is simple. These were RAF issued watches from the Second World War. They were made to a practical military specification, produced in limited wartime conditions and intended to be used. The result is a watch that feels direct, purposeful and historically important.
For Jaeger LeCoultre collectors, the 6B/159 is also an important reminder that the manufacture was not only making refined dress watches. It was producing high quality instrument watches for serious use. The calibre 470 manual wind movement, the military case back markings and the original dial layout all contribute to the appeal.
For military watch collectors, this is exactly the sort of piece that matters. Honest condition, clear markings, wartime production and a design that exists because of purpose rather than fashion.
Every watch we sell is fully inspected and professionally serviced where required to meet our exacting standards. All purchases are supplied with bespoke Watts On Watches packaging, full purchase documentation and a 12 month warranty as standard.
