The JLC Mark 11 Is Military Watch That Matters. Commissioned By The British Ministry Of Defence From 1948-'53, With Fewer Than 3000 Produced By JLC.

A Pure Expression Of The Time & Sentiment, Embodying The Ideals Of Precision & Uncompromising Standards.

Typically issued to military pilots, the “RAAF” Mark XI’s were first introduced to navigators in the Royal Australian Air Force (RAAF) in 1950. It is one of the rarest Military issue watches in existence. For connoisseurs, the Jaeger-LeCoultre Mark XI is not merely a military tool but a cornerstone of horological heritage. This 1953 RAAF-issued example stands as both a functional masterpiece and a collector’s prize — a watch that bridges wartime necessity and timeless design.

What sets the Mark XI apart is its purpose-driven purity. Every element was engineered for utility: anti-magnetic shielding, water resistance, and a no-frills design built to serve rather than dazzle. Yet today, collectors admire it for exactly those qualities — the honesty of its construction, the elegance of its restraint, and the provenance that connects each piece to a chapter of aviation history.
