M79643-0005 • 36mm Steel & Yellow Gold • Champagne Dial • Full Set
Offered for sale is a 2025 Tudor Black Bay One 36 S&G, reference M79643-0005. This refined two-tone model combines the versatile proportions of a 36mm case with stainless-steel construction, genuine yellow-gold accents, and a warm champagne-colored dial.
The polished and satin-finished stainless-steel case features Tudor’s signature Snowflake hands, applied luminous hour markers, and a fixed bezel capped in yellow gold. The watch is paired with a steel-and-yellow-gold bracelet equipped with Tudor’s T-fit rapid-adjustment clasp, allowing for convenient sizing and added everyday comfort.
Powering the watch is Tudor’s COSC-certified Manufacture Calibre MT5400, an automatic movement providing approximately 70 hours of power reserve. A screw-down winding crown and 100 meters of water resistance add everyday practicality to the Black Bay One’s refined design.
Dated October 22, 2025, this example comes as a complete full set with its original Tudor inner and outer boxes, warranty card, manuals and booklets, additional bracelet links, and accompanying accessories.
