BACK TO COLLECTIONTHE BISHOP
Invited by the Wright family to produce a limited-edition time series honoring the legacy of early aviation, Call Sign presents The Bishop—a rare mechanical timepiece dedicated to Milton Wright, the father and steady guiding force behind Wilbur and Orville Wright.
Limited to just 50 individually numbered pieces, The Bishop commemorates the quiet influence that shaped history. The caseback is engraved with the Penaud helicopter, the simple flying toy Milton brought home for his sons—an object that ignited a lifelong fascination with flight and ultimately changed the world.
More than a watch, The Bishop is a tribute to mentorship, conviction, and the unseen hands that lift pioneers into motion. Every detail reflects Milton Wright’s role in fostering curiosity, discipline, and perseverance—values as essential to aviation as lift and thrust.
This timepiece stands as a reminder that great achievements are often born not only from bold ideas, but from those who believe in them first.
Only 50 will ever be made. Once claimed, this chapter of the Wright legacy is closed forever. Secure your place in aviation history while The Bishop remains available.
