The French name "montre d'aèronef" is a name with rich connotations. Initially, these aircraft instruments were specially designed for flight, and the conditions of use were extremely harsh. Machines must undergo severe tests, such as sudden changes in temperature, violent vibration, changes in humidity and air pressure intensity. When reading, the clarity should also be impeccable: the large black matte dial forms a sharp color difference with the hands and time scales coated with white fluorescent materials, and the Arabic numeral time scales are also oversized. In order to make the operation of the watch more convenient, the crown is specially designed so that the pilot can easily adjust the watch even if he wears gloves.
