The Rolex GMT-Master II Black-Red "Coke" Bezel Error is a rare and highly sought-after collector’s item, known for its distinctive bezel color and production anomaly. Featuring a 40mm case crafted from Rolex's durable Oystersteel, this timepiece combines functionality with style, characteristic of the GMT-Master II collection. What sets this model apart is its iconic "Coke" bezel, a combination of black and red, which is reminiscent of the classic GMT-Master II design. However, this particular version is distinguished by an error in the bezel manufacturing process that resulted in a unique color variation—often regarded as a manufacturing flaw, it has become highly desirable among collectors due to its rarity.
