The Tudor Black Bay Ceramic Blue 79210CNU introduces a dramatic expression of the Black Bay aesthetic with a scratch-resistant 41 mm micro-blasted matte black ceramic case and bezel. The unidirectional diver bezel features a black ceramic insert with satin-sunburst finish and engraved markers, while the screw-down black PVD steel crown ensures 200 m water resistance and professional robustness. Its vivid deep blue domed dial is framed by high-contrast luminous snowflake hands and applied baton markers filled with Super-LumiNova—offering maximum clarity both day and night. The overall aesthetic maintains Tudor’s signature retro-inspired design language while bonded with modern material engineering for a contemporary twist. At its core is Tudor’s manufacture automatic Calibre MT5602-1U, co-developed with Kenissi, certified as a Master Chronometer for precision within –2/+4 sec/day and anti-magnetic resistance up to 15,000 gauss. With a 70-hour power reserve, a blackened rotor visible through the sapphire caseback, and paired straps—a hybrid rubber-leather with blue stitching plus an optional blue-striped fabric NATO—the 79210CNU blends performance, style, and personality in a sleek, all-ceramic expression of Tudor’s elevating capabilities.
