About this watch
The Tudor Black Bay Chrono 39 M79310N-0001 was introduced in 2025 as a 39 mm stainless steel chronograph within the Black Bay collection. This reference has a polished and satin-finished stainless steel case measuring 13.1 mm thick and 47 mm from lug to lug. It is fitted with a fixed stainless steel bezel with a black anodized aluminum insert and tachymeter scale, a screw-down crown, screw-down chronograph pushers, and a domed sapphire crystal. Water resistance is rated to 200 meters.
The domed yellow dial has black sub-counters and a date aperture at 6 o’clock. The chronograph display consists of a central chronograph seconds hand, a 45-minute counter at 3 o’clock, and small seconds at 9 o’clock. The watch uses Tudor’s Snowflake hour and minute hands, with Grade A Swiss Super-LumiNova for low-light legibility.
The watch is powered by the Manufacture Caliber MT5813, a self-winding mechanical chronograph movement with a bidirectional rotor system. The caliber uses a column wheel, vertical clutch, non-magnetic silicon balance spring, variable-inertia balance, and stop-seconds mechanism. It runs at 28,800 vibrations per hour, has 41 jewels, and provides a power reserve of approximately 70 hours. The movement is COSC-certified, with Tudor applying a stated tolerance of -2/+4 seconds per day to the fully assembled watch.
This reference is fitted with a three-link stainless steel bracelet with polished and satin-brushed finishes and smooth link sides. The bracelet is equipped with Tudor’s T-fit rapid adjustment clasp, which allows tool-free adjustment across an 8 mm range.
