The Rolex Cosmograph Daytona reference 126506-0002 is a premier 40mm luxury chronograph crafted from 950 platinum, representing the pinnacle of the collection’s engineering. This model is distinguished by its signature ice blue dial, a color reserved exclusively for Rolex’s platinum timepieces, which features eight baguette-cut diamond hour markers and three diamond-set markers at the 3, 6, and 9 o’clock positions. The dial is framed by a fixed chestnut brown monobloc Cerachrom ceramic bezel with a molded tachymetric scale, allowing for average speed measurements up to 400 units per hour. For the first time in the Daytona’s history, this generation features a transparent sapphire caseback, revealing the meticulously finished movement within.
Powering the watch is the in-house caliber 4131, a self-winding mechanical chronograph movement that provides a power reserve of approximately 72 hours. This updated caliber incorporates the Chronergy escapement for better energy efficiency and Paraflex shock absorbers for increased resilience. The 40mm Oyster case utilizes a Triplock triple waterproofness system and screw-down pushers to ensure water resistance up to 100 meters. It is paired with a solid three-piece link platinum Oyster bracelet equipped with a folding Oysterlock safety clasp and the Easylink 5mm comfort extension link for easy adjustments.
General reviews of the 126506 often emphasize its significant weight and substantial wrist presence, noting that platinum is considerably denser than stainless steel or gold. Enthusiasts frequently praise the unique color harmony between the ice blue dial and the chestnut brown bezel, which creates an aesthetic that is both sporty and exceptionally luxurious. The addition of the exhibition caseback is widely regarded as a welcome evolution, allowing collectors to appreciate the refined Côtes de Genève decoration on the movement’s bridges. While its high market value and scarcity make it a “grail” watch for many, some reviewers note that its hefty weight may require a well-fitted bracelet to ensure comfort during daily wear.
