The Rolex Cosmograph Daytona reference 126506-0001, frequently referred to by collectors as the Platona, is a 40mm luxury chronograph crafted from 950 platinum. This model features an exclusive ice blue dial, a color reserved specifically for Rolex’s platinum timepieces, paired with chestnut brown rings around the sub-dials. The watch is distinguished by its fixed chestnut brown monobloc Cerachrom ceramic bezel with an engraved tachymetric scale. A notable update for this generation is the inclusion of a transparent sapphire crystal case back, which allows a view of the movement while maintaining a water resistance of 100 meters. The timepiece is fitted with a solid three-link platinum Oyster bracelet equipped with a folding Oysterlock safety clasp and a 5mm Easylink comfort extension.
Powering the watch is the manufacture caliber 4131, a self-winding mechanical chronograph movement that provides a power reserve of approximately 72 hours. This caliber is a Superlative Chronometer, ensuring a precision of -2/+2 seconds per day. The movement incorporates a column wheel and vertical clutch for smooth operation of the chronograph functions, which include a central sweep seconds hand, a 30-minute counter at 3 o’clock, and a 12-hour counter at 9 o’clock. It also features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers for increased resistance to environmental stressors and shocks.
General reviews of the 126506-0001 are overwhelmingly positive, often highlighting its incredible wrist presence and the substantial weight that accompanies its platinum construction. Collectors frequently praise the aesthetic harmony of the ice blue and chestnut brown color scheme, noting that it creates a unique and sophisticated appearance that is easily recognizable to those in the know. The addition of the open case back is widely regarded as a welcome evolution, offering a rare look at Rolex’s movement finishing. While the watch’s significant weight and high market price are occasionally noted as factors for consideration, it is considered a pinnacle piece in the Daytona lineup and a highly coveted investment for serious enthusiasts.
