BACK TO COLLECTIONTHE KATHARINE
Invited by the Wright family to produce a limited-edition time series honoring the forces that shaped aviation history, Call Sign presents The Katharine—a mechanical timepiece dedicated to Katharine Wright, whose intellect, advocacy, and unwavering resolve were essential to the Wright brothers’ success.
Limited to 100 individually numbered pieces, The Katharine honors the influence behind the invention. While Wilbur and Orville engineered flight, Katharine carried their vision to the world—managing international relationships, championing their work abroad, and ensuring their achievements received global recognition.
Her contributions were formally recognized when she was awarded the French Legion of Honor alongside her brothers, a rare distinction that affirmed her vital role in aviation history. The caseback is engraved with the 1905 Wright Flyer III, the first practical airplane and the aircraft that proved their achievement on the world stage—made possible through Katharine’s steadfast support.
The Katharine is more than a watch—it is a tribute to leadership, conviction, and the quiet strength that carries innovation forward.
Only 100 will ever be made. Once claimed, this expression of the Wright legacy will never be produced again. Secure yours while availability remains.
