The TUDOR BLACK BAY GMT S&G, M79833MN-0003, marries sophistication with functionality. Encased in a 41mm steel case, the watch features a harmonious blend of polished and satin finishes. Its heart, the COSC-certified Manufacture Calibre MT5652, powers the self-winding mechanical movement with a bidirectional rotor system, embracing a built-in architecture and offering a robust 70-hour power reserve. The screw-down winding crown, adorned with the TUDOR rose and a 0.3mm yellow gold cap, secures a waterproofness of 200m (660 ft). The 48-notch bidirectional rotating bezel, in steel core covered by a 0.3mm yellow gold cap, boasts a 24-hour graduated matt brown and black anodised aluminium disc. A black domed dial, beneath a sapphire crystal, and a brown leather strap with a steel folding clasp complete this horological masterpiece.
