The iconic IWC Mark XI, launched in 1948, represents a historic collaboration between the International Watch Company (IWC) and Jaeger-LeCoultre (JLC). These timepieces were carefully crafted to the strict specifications of the British Ministry of Defence (MoD), with functionality as the top priority. And the result? Watches that have withstood the test of time as classics.
All Mark XI watches were subjected to rigorous testing in the chronometer workshop of the Royal Greenwich Observatory in Herstmonceux. And for good reason, because the accuracy had to meet the specifications of the users, they were supplied to the R.A.F., FAA (Fleet Air Arm), RAAF (Royal Australian Air Force) RNZAF (Royal New Zealand Air Force), among others. The IWC Mark XI was used by the airforce pilots since its introduction and was finally retired in 1981.

CASE
36 mm stainless steel with screwed back signed with the "Broad Arrow". The Broad Arrow was used in Britain to mark objects purchased by the British Government.
DIAL
The white dial with Arabic numerals is made of soft iron and, together with the dust cover over the movement, forms an anti-magnetic, so-called Faraday cage.
MOVEMENT
The watch is equipped with the famous cal. 89 movement built into a stainless steel case. The movement is equipped with 16 jewels and the escapement consists of a non-magnetic "Glucydur" balance with a self-compensating, non-magnetic "Nivarox" hairspring.
