Tudor Black Bay Chrono M79363N-0001 41 mm Black Dial

The Tudor Black Bay Chrono M79363N-0001 places a black satin dial and tachymeter bezel inside a 41 mm case with a rich material mix. The case is steel, while yellow gold appears on the bezel and bracelet, sharpening the round profile. A domed sapphire crystal, screw-down crown and pushers, Super-LumiNova and 200-metre water resistance keep the watch connected to the Black Bay Chrono's robust brief. Its 14.4 mm thickness reinforces its presence.

The MT5813 automatic calibre is a Breitling B01-derived manufacture chronograph modified by Tudor. A column wheel and vertical clutch control the chronograph, while a free-sprung variable-inertia balance, flat silicon hairspring and 41 jewels support its 28,800-vibrations-per-hour frequency. The movement stores 70 hours of power and carries COSC Chronometer certification. Within Black Bay Chrono, this reference is the yellow-gold bezel and bracelet configuration, retaining chronograph architecture while changing the case and dial contrast.
