Tudor Black Bay GMT Pepsi

Tudor Black Bay · Ref. M79830RB-0001

About This Watch

The Tudor Black Bay GMT burst onto the scene in 2018 and immediately became one of the most talked-about watches in the industry, offering a true GMT function — independently adjustable local hour hand — at a price point that was previously unthinkable. The red and blue "Pepsi" bezel, rendered in anodized aluminum, pays homage to the iconic Rolex GMT-Master colorway but with Tudor's own distinctly angular snowflake hands and shield logo giving it its own identity. The MT5652 manufacture caliber is purpose-built for the GMT function, not a modified time-only movement, which means the additional complication does not compromise reliability or servicing simplicity. With COSC certification and a 70-hour power reserve, the movement punches well above the watch's price class. The bidirectional rotating bezel allows tracking of a third time zone beyond the two displayed by the GMT hands, making this a genuinely functional travel watch. At its MSRP of just over $4,000, the Black Bay GMT undercuts the Rolex GMT-Master II by a factor of three while offering comparable core functionality and manufacture movement quality. The market has responded accordingly — this is one of Tudor's most popular models and has maintained secondary market prices at or above retail since launch. For frequent travelers seeking a true GMT watch without the Rolex premium, this is the definitive choice.
