The Cosmograph Daytona 126500LN is one of Rolex's signature professional chronographs, characterized by its 40 mm Oyster case, black Cerachrom tachymetric bezel and three-register chronograph layout. The original Rolex 126500LN is equipped with the in-house Calibre 4131 automatic chronograph movement and approximately 72 hours of power reserve. This BLAKEN customized version features a distinctive pink dial with contrasting black chronograph counters and a matching customized design. The Oyster-style bracelet and stainless-steel construction retain the sporty character of the Daytona while the customized dial gives the watch a significantly different appearance.
