The Tudor Black Bay Yellow Gold & Steel Champagne Dial 31mm Ref. M79603-0005 delivers a distinctive two-tone look with proven Tudor engineering in a compact format. Released in 2022, this watch features a 31mm stainless steel case with polished and satin surfaces, matched by a fixed solid yellow gold bezel for a refined contrast. The champagne-colour dial is paired with luminescent index and dot markers, all protected by a flat sapphire crystal. Inside, the COSC-certified Manufacture Calibre MT5201 ensures a 50-hour power reserve and reliable chronometer accuracy. A screw-down crown, crafted in steel and capped with 0.1mm yellow gold, bears the Tudor rose and provides water resistance to 100 meters. The bracelet integrates steel and yellow gold links, secured with Tudor’s “T-fit” folding clasp and solid gold logo. This reference is notable for its blend of technical performance, versatile proportions, and signature two-tone design.
