Vintage IWC Mark XI Military Pilot's Watch RAF Issue 1948 Ref. 6B/346 - Caliber 89

Secure an absolute holy grail of military horological history. The IWC Mark XI (Mark 11) is universally regarded by collectors and historians as one of the finest, most rigorously engineered military pilot watches ever manufactured. Commissioned by the British Ministry of Supply (MoS) for the Royal Air Force (RAF), this exact timepiece is a legendary survivor from the highly coveted premier delivery year of 1948.

The watch features its sterile, matte black military dial bearing the proud full-script "International Watch Co." signature, the military broad arrow, and the circled "T" tritium designation indicator. Built explicitly to solve the extreme navigational issues faced by aviators, the brushed steel case houses an internal anti-magnetic soft iron inner shield that completely isolates the mechanical heart from cockpit magnetic interference.

Flawless Military Caseback Engravings:

The true confirmation of this timekeeper's historical pedigree is deeply etched onto its solid stainless steel screw-down caseback. It features the sharp, original British military property stamps: the broad arrow symbol (Pheon), the official specification code 6B/346, and its individual military store issue number 596/48, firmly tracing its delivery back to 1948.
