The Tudor Black Bay takes a 20mm or 22mm strap depending on the reference. This perforated calfskin leather Tudor Black Bay strap replacement is inspired by vintage motorsport and aviation design — the same perforation aesthetic found on the racing straps worn alongside chronographs and pilot watches decades before either became collector pieces.
The perforations are the detail that separates this from a standard calfskin strap. Evenly spaced across the full-grain calfskin surface, they reduce weight, increase ventilation and give the strap a purposeful, tactile character that suits the Black Bay's tool watch DNA precisely. On the wrist it breathes well, sits flat and looks considered rather than decorative.
Premium calfskin leather, supple from first wear and built to develop character over time. Available in black, tan and brown to complement the full range of Black Bay dial and bezel combinations. The black on a Black Bay 58 black dial creates a clean, monochromatic combination. Tan against the gilt accents and warm lume of the Black Bay 58 original is the most classic pairing. Brown for the collectors who want warmth without the brightness of tan.
Quick-release spring bars fitted as standard for tool-free strap changes. A genuine Tudor black bay leather strap replacement built for daily wear.
