Tudor Black Bay One M79663-0005 39 mm Champagne Dial

The Tudor Black Bay One M79663-0005 combines the 39 mm steel case with a satin champagne dial for a warmer take on the collection's geometry. The fixed steel bezel, silver stainless steel bracelet and flat sapphire crystal keep the design precise, while a screw-down crown, Super-LumiNova and 100-metre water resistance retain its practical Black Bay credentials. With a 12 mm thickness, the case remains substantial but contained in the 39 mm format.

The automatic MT5602 calibre uses a Tudor/Kenissi manufacture platform, with 25 jewels and a full openworked tungsten monobloc rotor. Measuring 31.8 mm in diameter and 6.5 mm high, it pairs a free-sprung variable-inertia balance with a flat silicon hairspring at 28,800 vibrations per hour. The movement offers a 70-hour power reserve and COSC Chronometer certification. In Black Bay One, this reference has a champagne dial in the 39 mm steel-bracelet layout.
