Tudor Black Bay One M79680-0002 41 mm Blue Dial

The Tudor Black Bay One M79680-0002 uses a 41 mm steel case to give its satin blue dial a clean setting. A fixed stainless steel bezel, flat sapphire crystal and silver stainless steel bracelet keep the palette cool, while the screw-down crown, Super-LumiNova and 100-metre water resistance carry its specification. At 12.2 mm thick, its round profile has the presence associated with the 41 mm Black Bay One format.

The automatic MT5601 calibre is based on a Tudor/Kenissi manufacture platform, with 25 jewels and a full openworked tungsten monobloc rotor. It measures 33.8 mm across and 6.5 mm high, using a free-sprung variable-inertia balance secured by a traversing bridge and a flat silicon hairspring. Running at 28,800 vibrations per hour, it provides 70 hours of power reserve and COSC Chronometer certification. In Black Bay One, this is the largest steel configuration with a blue dial.
