Functional, precise and reliable, these “wrist instruments” from the AirBoss collection have been designed with aeronautics professionals in mind. The bidirectional rotating flange can be used to calculate the countdown for aeroplane takeoff, while the push-buttons on the left of the chronograph and the overdimensioned crown make for easy adjustment.
