The British Armed Forces made use of both the Jaeger-LeCoultre Mark XI RAF Navigators 6B/34 and the IWC Mark XI, with the latter in use up until 1981. For pilots, there were monopusher chronographs from the likes of Lemania, Breitling, and Rodania, as well as an Omega 6B/542 which was an RAF pilots' watch used back in 1953.
A recurring theme that we continue to see within this period is the repackaging of older watches – perhaps leaning towards tradition – alongside more innovative movements.
The period between 1950 and 1956 also saw three separate production runs for the Waltham A-17 for use in the Korean War by pilots in the U.S. military, a modified version of the Waltham A-11 that saw action in World War II. Other pieces made by Elgin and Bulova were also made according to this specification.
The combination of repackaging wartime watches alongside the adoption of newer movements was particularly true for the German and Italian Flieger and B-Uhren watches (pilots’ and navigators’, respectively) as some were reissued versions of wartime Flieger chronographs. The Flieger, or “flyback” function, for instance, was a required specification that stopped, started, and reset the chronograph through the lower button. The 1950s and 1960s saw the introduction of the Hanhart 417 ES, famously associated with Steve McQueen, in addition to pieces like the Heuer-Leonidas Bundeswehr which was supplied to both German and Italian forces, and the Junghans J88.
