The Tudor Black Bay Chrono Ref. 79360N is a masterful fusion of heritage dive-watch robustness and racing-inspired precision, representing a landmark achievement in Tudor’s modern lineup. Housed in a 41mm stainless steel case with a mix of polished and satin-brushed finishes, this professional-grade timepiece features a fixed steel bezel with a matte black anodized aluminium tachymeter insert. The striking black dial provides a perfect backdrop for the contrasting white or silver chronograph sub-counters – a classic “reverse panda” configuration that ensures excellent legibility. At its heart beats the exceptional in-house Manufacture Calibre MT5813 (COSC-certified), a self-winding movement developed in collaboration with Breitling, renowned for its advanced column-wheel and vertical clutch chronograph architecture, a silicon balance spring for superior anti-magnetic performance, and an impressive 70-hour power reserve. Combining the water resistance of a diver’s watch (200 meters) with the functionality of a chronograph, this timepiece is secured by a stainless steel 5‑link “Jubilee” style bracelet featuring Tudor’s innovative T‑fit clasp for rapid, tool-free micro-adjustment, ensuring a perfect and comfortable fit. With its screw-down crown and pushers, this 14.4mm-thick instrument is a highly compelling and capable “workhorse” watch, offering exceptional value and technical sophistication for the discerning collector who demands both motorsport heritage and everyday ruggedness. Key specifications: 41mm steel case; black dial with contrasting sub-dials; in-house Calibre MT5813 (COSC); 70-hour power reserve; steel bracelet with T-fit clasp; 200m water resistance; sapphire crystal.
