Tudor Black Bay One M79643-0002 36 mm Silver Dial

The Tudor Black Bay One M79643-0002 presents the 36 mm steel case with a satin silver dial and fixed steel bezel. Its 10.5 mm thickness gives the round watch a compact profile, while the silver stainless steel bracelet continues the bright impression. A flat sapphire crystal, screw-down crown and Super-LumiNova keep the specification focused, and 100-metre water resistance places this reference within the practical Black Bay One format.

The automatic Tudor MT5400 calibre uses a Tudor/Kenissi manufacture platform and a full openworked tungsten monobloc rotor. It contains 27 jewels and measures 30.3 mm in diameter by 5 mm in height. A free-sprung variable-inertia balance with flat silicon hairspring beats at 28,800 vibrations per hour, while the movement provides 70 hours of power reserve and carries COSC Chronometer certification. This reference sits in the Black Bay One family as the steel-bracelet version with a silver dial.
