Hello r/watchexchange! Up for sale today is my sold out Smiths Navigator. As the story goes, in 1946/47 the RAF decided that they needed a more reliable timepiece for timing navigation during bombing raids. The main requirements were chronometer grade, high anti-magnetic properties (12,000A/m), and good legibility. Two companies eventually won the contract: International Watch Company (IWC) and Jaeger LeCoultre (JLC), and the watches, both designated Mk 11, entered service in 1949. "Mk 11" is the Air Ministry designation for the watch -- it is not a manufacturer's model number. The Smiths Navigator is a faithful revival of the Mk 11, using the original Air Ministry specification but with higher anti-magnetic properties (20,000A/m) and a sapphire crystal. My particular example was purchased new in Nov 2020. I am the second owner. Anyways, below are the quick specs.
