Call Sign is an American watch brand founded by Beau Garrett — a commercial pilot and former flight instructor to Navy and Air Force officers — built around the meaning behind a single phrase: your call sign. In aviation, a call sign is more than a nickname. It is a marker of identity, something earned rather than chosen, born from a story, a moment in training, a breakthrough or a laugh. It signifies belonging — membership in something larger than oneself, carrying the weight of passion, sacrifice, and commitment. That ethos is the foundation of every Call Sign timepiece. The brand crafts purpose-built watches designed to honor service, craftsmanship, and the defining moments that shape the people who wear them. The Discovery collection — available in 42mm and 38mm — features Zulu time display for quick dual time zone tracking, practical for pilots and frequent flyers alike, with each watch engraved on the back with the wearer's pilot certificate number. The Wright Brothers collection pays homage to the pioneers of aviation, while The Bishop, The Brothers, and The Katharine offer elevated options for more formal occasions. Call Sign also works with organisations such as the American Legion, extending the brand's connection to service and community.
