The Tudor Black Bay GMT Ref. M79830RB-0010 is a bold and sophisticated travel watch, masterfully pairing the collection’s iconic dive-watch DNA with the highly sought-after “Pepsi” aesthetic in a stunning new opaline white dial configuration . This 41mm stainless steel timepiece features a bidirectional rotatable bezel with a matte burgundy and blue anodized aluminium 24-hour disc, framing a domed opaline white dial with a galvanic finish that provides a crisp, contemporary contrast to the vibrant bezel . The dial is equipped with Tudor’s signature angular “Snowflake” hands and applied hour markers, all filled with luminous material for exceptional legibility, alongside a practical date window at 3 o’clock . At its heart beats the in-house Manufacture Calibre MT5652 (COSC), a self-winding mechanical movement with a bidirectional rotor system that delivers an impressive 70-hour power reserve and authentic GMT functionality, allowing the independent adjustment of the local hour hand to track a second time zone . Completed by a robust riveted stainless steel bracelet with a folding clasp and safety catch, and offering a water resistance of 200 meters, this neo-vintage icon offers the discerning collector a perfect synthesis of Tudor’s heritage design, modern technical innovation, and the distinctive versatility of the white opaline dial . Key specifications: 41mm steel case; opaline white dial; Calibre MT5652 (COSC) automatic movement; 70-hour power reserve; steel bracelet; 200m water resistance.
