22298, Aero-Compax, Steel
A ref. 22289 Aero-Compax, a 35mm chronograph in steel with a ‘reference time’ complication in the 12 o’clock subdial set via an independent left-hand crown. The reference time was demanded by WWII pilots, who needed to track more than a simple chronograph could manage, such as elapsed mission time plus time to target. Shown here with sword hands and an eggshell patina dial, this is a mid-century aviation aesthetic not many watches can match.
