The Tudor reference 76160, part of the "Big Block" chronograph series, retains the signature design elements of its 9400-series predecessors while embracing a modernized aesthetic. Introduced in 1989, this first-generation model features a striking silver dial with black sub-dials, a black tachymeter bezel, and classic “OYSTERDATE” and “AUTOMATIC - CHRONO TIME” designations. Authentic details such as the "T SWISS T" marking, trapezoidal hour markers, and a caseback from the earlier reference 9420 bearing the Rolex signature highlight its transitional nature. Additionally, the Rolex-signed Triplock crown and upgraded Tudor 78360 bracelet enhance its durability. Powered by the reliable Valjoux 7750 movement with a distinctive half-moon rotor, this watch combines robustness with timeless appeal.
