IWC Mark XI is a legendary model built to the stricter specifications required by pilots in their duties. The British MOD requested a highly accurate movement with hacking for precise time-setting, a Faraday cage offering protection against magnetic interference, a stainless steel, waterproof case with a screwed ring to protect the crystal in the event of a sudden drop in air pressure, and a black dial with luminous hands. Upon delivery, these watches were subjected to an exhaustive, 44-day testing period for ‘Navigator Wrist Watches’. Each batch then had to be sent, every year, to the chronometer workshop at the Royal Greenwich Observatory in Herstmonceux for re-calibration. This model was driven by the IWC Calibre 89, and although the last Mark XI was delivered to the RAF in 1953 it was not officially decommissioned until 1981. IWC actually sold around a thousand through its commercial network, while XIs were still being issued to pilots and navigators of the BOAC (British Overseas Airways Corporation).

IWC MARK XI produced for civilian market are much rarer than MARK XI for military market, according to our research only 500 pieces were produced for civilian market.
