About this piece

A modern tribute to Tudor’s legendary dive watches of the 1950s, the Black Bay Heritage 79230N blends timeless design with cutting-edge watchmaking. Featuring a robust 41mm stainless steel case with polished and satin finishes, this timepiece is powered by Tudor’s in-house Calibre MT5602—a COSC-certified automatic movement offering a 70-hour power reserve. The watch showcases a domed black dial with luminous snowflake hands and hour markers for optimal legibility, even in low-light conditions. Its unidirectional rotatable bezel with a matte black anodized aluminum insert adds a distinctive vintage flair, while the screw-down crown ensures water resistance up to 200 meters (660 feet).
