Type 20 Chronographe 2057
This model takes its inspiration from the 1,100 watches delivered to the French Air Force between 1955 and 1959 and whose name was written as Type 20 with Arabic numerals. Featuring a 42 mm case made of steel.
Its black dial has been modernised all while remaining faithful to the Type 20 identity. The Arabic numerals and the triangle present on the bezel are luminescent and feature a mint green hue, as do all the hands. The 30-minute counter at 3 o’clock, is now larger than the 60-seconds counter displayed at 9 o’clock, while a date aperture has been added at 4:30.
