As follows a description of how the timer was used.
The luminous numerals indicate the distance travelled by a dropped bomb in hm (hectometer: 100 meters). The operator, knowing the launch altitude, would set the arrow at the corresponding distance. Then, he would use the crown to start the timer, and press the button once the hand reached the desired distance to stop it. When the bomb is dropped, one more push on the crown would set the hand in motion counterclockwise, thus starting the countdown to the moment the bomb would reach the ground. At this point, another push on the button would stop the timer, and a last activation of the crown would reset the hand.
