The TUDOR Black Bay GMT M79830RB-0001, commonly nicknamed the “Pepsi” for its burgundy-and-blue bezel, combines the vintage-inspired character of the Black Bay with a highly practical travel complication. Its 41mm stainless steel case surrounds a domed black dial with TUDOR’s signature Snowflake hands, while the two-tone 24-hour bezel gives the watch its unmistakable GMT appearance. The riveted steel bracelet completes the heritage-inspired aesthetic.

Inside is TUDOR’s Manufacture Caliber MT5652, a COSC-certified automatic movement developed specifically around an integrated GMT architecture. Unlike a basic caller GMT, the MT5652 allows the local hour hand to jump independently in one-hour increments, making it particularly convenient when traveling between time zones. The date is synchronized with the jumping local-hour hand, while the red 24-hour hand tracks reference or home time. The bidirectional bezel can also be used to read a third time zone. Power reserve is approximately 70 hours.

With 200 meters of water resistance, robust steel construction, a true traveler-style GMT movement, and the instantly recognizable burgundy-and-blue bezel, the Black Bay GMT delivers an appealing combination of dive-watch durability and international travel functionality. The M79830RB-0001 has become one of the most recognizable references in the modern Black Bay family and an excellent choice for collectors looking for a versatile everyday TUDOR.
