The Black Bay Chrono features TUDOR’s “T-fit” rapid adjustment clasp, offering an easy, tool-free system with five positions for fine, instant adjustments up to 8mm. Powered by the Manufacture Chronograph Calibre MT5813, it displays hour, minute, second, chronograph, and date functions. Its rotor in tungsten monobloc features openwork, satin-brushed details, with sand-blasted bridges and polished surfaces. The 41mm stainless steel case, with polished and satin-brushed finishes, is waterproof to 200m and features a domed sapphire crystal. The opaline dial with black counters and tachymetric scale adds elegance, while the 3-link stainless steel “rivet-style” bracelet ensures a secure fit with the “T-fit” clasp.
