The Tudor Black Bay Yellow Gold & Steel Champagne Dial 36mm Ref. M79643-0005 delivers reliable performance and a refined two-tone look in a versatile case size. Introduced in 2022, this model features a 36mm stainless steel case with polished and satin finishes, paired with a fixed bezel in steel covered by a 0.3mm yellow gold cap. The champagne-colour dial is equipped with luminescent index and dot markers for clear visibility, all protected by a flat sapphire crystal. Inside, the COSC-certified Manufacture Calibre MT5400 provides a 70-hour power reserve, self-winding mechanical movement, and chronometer-rated accuracy. The screw-down crown, in steel and capped with yellow gold, features the Tudor rose and maintains water resistance up to 100 meters. Completing the watch is a two-tone bracelet combining steel and yellow gold links, secured with the Tudor “T-fit” folding clasp and a solid gold logo. This reference stands out for its advanced movement and classic two-tone construction.
