A Boselli radio clock . A vintage mechanical clock made during World War II by E. Boselli Milano for O.M.T. Roma (Officine Militari Trasmissioni).
Key Details
Origin: Manufactured in Italy during WWII. Enrico Boselli (based in Milan) was an importer of high-quality Swiss movements and clocks, while O.M.T. (based in Rome) supplied military radio equipment and transmission gear to the Italian Armed Forces.
Purpose: These small, robust 7-day or 8-day mechanical bezel-wound clocks were built directly into military radio communication sets or used as vehicle/aircraft cockpit clocks to help coordinate timed radio transmissions.
Design: They usually feature a blackened metal casing, a clear glass face with a bezel-winding/setting mechanism, and a small sub-second dial.
Collectibility: Today, they are rare military-surplus collectibles prized for their aviation and military communications history.
Very good cosmetic condition with a crisp dial. The bezel winding and setting mechanism works well. Runs for a few seconds before stopping so will need attention. Balance wheel ok.
