The Tudor Black Bay GMT Yellow Gold & Steel Black Dial 41mm Ref. M79833MN-0001 brings dual time zone capability to a refined two-tone sports watch. The 41mm case is crafted from stainless steel with polished and satin finishes, paired with a robust 14.6mm profile. The bidirectional 48-notch rotating bezel features a steel core covered by a yellow gold cap and a 24-hour graduated matt brown and black anodised aluminium insert. The domed black dial is highly legible, with luminescent dot and index markers. Powered by the COSC-certified Manufacture Calibre MT5652, this model delivers a 70-hour power reserve, self-winding functionality, and chronometer precision. The screw-down crown is accented with the Tudor rose in black lacquer and a matching gold cap. The bracelet blends solid yellow gold center links at 6 and 12 o’clock with gold-capped steel links elsewhere. Waterproof to 200 meters, the Black Bay GMT stands out for its travel-ready features and two-tone construction.
