Why We Love it

Through much of World War II, allied aviators were donning the American-made A-11 service watch. While this tough-as-nails timekeeper performed meritoriously for soldiers and airmen alike, Britain's Ministry of Defense found that the production specifications of the A-11 were too broad and resulted in timepieces too imprecise for effective navigation.

As an answer to the A-11, the MoD issued new standards for the watches issued to its RAF pilots. The new standard, coded 6B/346, required chronometer-grade performance and anti-magnetic properties. For the production of this new timepiece, the MoD turned to major European manufactures, eventually giving contracts to two: International Watch Company and Jaeger-LeCoultre.

The resulting timepiece was the Mark XI Pilot's watch.

In addition to the relatively standard features present on the A-11 (center seconds, hacking and a stainless steel case), the Mark XI featured a soft iron dial and dust cover which shielded the movement from magnetism.

While IWC produced their version of the Mark XI with their existing Calibre 89 (which found its way into many IWC models of the era), Jaeger-LeCoultre filled their orders with a 12.5 ligne, 16-jewel Calibre 488/SBr movement — a movement that was only used in the Mark XI series — making the JLC executions much more sought after by collectors.

This particular example, issued to the Royal Australian Air Force, dates to circa 1953 and features a 34.6mm 'Staybrite' steel case with an acrylic crystal, a 'big' crown, a smooth bezel, and a matte black Radium' dial with printed 'Arabic' indices and a matching handset — in the unique style of the Mark 11 series, with a rectangular hour hand, a 'syringe' minute hand, and a white seconds hand.

This piece comes fitted to an Admiralty Grey Phoenix® NATO strap with stainless steel hardware and is powered by Jaeger-LeCoultre's Calibre 488/SBr hand-wound movement.

If you're a dedicated collector of military watches — or you simply have a respect and appreciation for well made things, history, or beautiful objects — it's going to be hard to pass up such an important timepiece as this!

Brand Story

+
Few watchmaking concerns are as storied as Jaeger-LeCoultre. Though the maison is not technically a member of the “Holy Trinity” of Patek Philippe, Audemars Piguet, and Vacheron Constantin, one could easily make the argument that it should be: After all, it was JLC that supplied movements to Patek from the beginning of the 20th century through the early 30s.

Founded in 1833 by Antoine LeCoutlre in Le Sentier, Switzerland, the firm became the Jaeger-LeCoultre we know today when it merged with Parisian watchmaker Edmond Jaeger’s business in 1937. The two horological concerns collaborated on numerous projects before cementing their partnership, the most important of which was no doubt the Reverso. A sport watch with a reversible case, this ingenious timepiece was designed to offer protection to the watch dial — when engaged in sport or otherwise dangerous activity, the wearer would simply flip the case over, exposing its back to the world, rather than the vulnerable crystal.

But the Reverso is far from the only significant timepiece brought to market by JLC: The firm also produced the world’s thinnest pocket watch in 1907, powered by the Caliber 145. In 1929, the maison released the Caliber 101, still today the smallest mechanical movement. (Queen Elizabeth II wore a Caliber 101-equipped wristwatch to her coronation in 1953.) And perhaps no other watchmaker is world-renowned for their production of a clock in the way that JLC is famous for the Atmos. Invented by Jean-Léon Reutter, it’s powered by miniscule changes in atmospheric pressure — Edmon Jaeger acquired the patent and licensed it beginning in 1936. The Atmos is still produced in numerous forms today, and remains the Swiss government’s foremost diplomatic gift.

From classic, near-centuries old designs like the Reverso and the Atmos to modern über-complications such as the brilliant Master Gyrotourbillon, Jaeger-LeCoultre remains on the cutting edge of horological technology nearly two centuries after its founding.
