Built for Service. Kept for a Lifetime. Timepieces That Stand at Attention.

For more than a century, Chelsea Clock has kept time alongside America’s airmen, beginning in 1917 with Chelsea’s first aircraft clocks, decades before the U.S. Air Force was established. After the Air Force became its own branch in 1947, Chelsea clocks went on to serve aboard Strategic Air Command bombers and in its missile silos, where precision was mission-critical. That legacy continues today with our officially licensed U.S. Air Force collection—crafted for airmen, veterans, families, and supporters. Each timepiece reflects the same American workmanship that once kept time in the cockpit, proudly bearing the U.S. Air Force insignia to honor its core values of Integrity First, Service Before Self, and Excellence in All We Do. A lasting tribute to service, heritage, and the strength of the U.S. Air Force.
