Tudor Black Bay Chrono

A chronograph built on a real dive-watch case is rarer than it sounds, and the Black Bay Chrono is the clearest example. Tudor developed the movement with Breitling — an unusual collaboration between two independent houses — producing a column-wheel, vertical-clutch automatic chronograph certified as a chronometer by the COSC. At 41mm with snowflake hands and a domed crystal, it keeps the vintage register while offering seventy hours of reserve.
