The TUDOR Black Bay GMT M79830RB-0010 introduces world-time functionality to the Black Bay line with unmistakable style. Its 41mm stainless steel case with polished and satin finishes houses a domed opaline dial with galvanic finish, offering a crisp backdrop for excellent legibility. The Manufacture Calibre MT5652, a COSC-certified chronometer with a built-in GMT function, delivers precision, robustness, and a 70-hour power reserve. A bidirectional 24-hour bezel in matte burgundy and blue anodised aluminium, known as the “Pepsi” bezel, allows tracking of additional time zones. The watch is waterproof to 200m and fitted with a screw-down crown bearing the TUDOR rose. Completing the design, a riveted stainless steel bracelet with polished and satin finishes, folding clasp, and safety catch ensures secure comfort both at home and abroad.
