More information
Manufactured in approximately 1939 by Universal Genève for the Italian Air Force, and retailed by the Roman watch supplier A. Cairelli, this rare WWII bomb timer was designed with a very specific purpose in mind: to measure the interval between a bomb’s release and its impact.
The black dial features luminous numerals that represent distance in hectometers (each equal to 100 metres), allowing the operator to match the timing to the aircraft’s altitude. By turning the crown, the user would set the arrow to the appropriate distance, then start the stopwatch as the bomb was dropped. A press of the button halted the hand at any moment, and another turn of the crown made the hand run backwards counting down to the exact second of impact. Finally, one more push of the button stopped the countdown, and another turn of the crown reset everything.
A Brief History of A. Cairelli
Established by Antonio Cairelli around 1932 at 144 Via del Corso in Rome, A. Cairelli functioned as a critical link between Switzerland’s finest watchmakers and the Italian Armed Forces. The firm imported specialised timepieces, most notably from Zenith and Universal Genève, according to rigorous military specifications and also provided service and maintenance. Despite its pivotal role, the company eventually closed in the 1960s or ’70s.
