Notes

The device for measuring time intervals applied to the Aero-Compax models was patented in Switzerland on December 15, 1944 under No. 235608.This model bears a single-coloured bezel, some others have a black and white bezel for day-time and night-time hours.This watch is the later version of the traditional Aéro-Compax Chronograph, in which the small memory display dial is replaced by a revolving bezel numbered from 1 to 24.Similar watches are published in Universal Genève, 100 ans de Traditions Horlogères by Italo Bonifacio and Laura Rivolta,pp. 68 and 69.
