Tudor 79830RB Black Bay GMT SS Black Dial

Launched in 2018, the Tudor Black Bay GMT ref. 79830RB has swiftly become a modern classic among collectors, marrying Tudor’s robust tool-watch heritage with a highly practical GMT complication. At its heart beats the in‑house calibre MT5652—an automatic, COSC‑certified movement offering a generous 70‑hour power reserve and a quick‑set local hour hand for seamless time‑zone transitions. The 41 mm stainless steel case, measuring approximately 14.6 mm thick and 50 mm lug‑to‑lug, is topped with a domed sapphire crystal and framed by the iconic red‑and‑blue “Pepsi” 24‑hour bezel, enabling tracking of a third time zone. Its matte black dial, accented by luminous snowflake hands and markers, offers exceptional legibility and a direct nod to Tudor’s vintage divers. Water‑resistant to 200 m, this GMT is equally at home on the wrist of a seasoned traveler or an enthusiast drawn to its technical substance and aesthetic symmetry. The reference’s collector appeal is further enhanced by its timing precision, in‑house movement, and the historical resonance of the Black Bay lineage. Offered here on a NATO strap, this variant adds a casual, utilitarian edge to an already compelling package—ideal for those seeking a refined yet adventurous GMT tool watch.
