The Rolex Cosmograph Daytona reference 126505-0001 is a 40mm luxury chronograph crafted entirely from 18k Everose gold, a proprietary rose gold alloy developed by Rolex to ensure the metal maintains its luster over time. This current-generation model features a refined Oyster case with a polished finish and a fixed Everose gold bezel engraved with a tachymetric scale. It is equipped with a bright black and sundust dial, protected by a scratch-resistant sapphire crystal. The watch is paired with a matching three-piece link Oyster bracelet, which includes a folding Oysterlock safety clasp and the Easylink 5mm comfort extension system for easy adjustments.
At the heart of this timepiece is the in-house caliber 4131, a self-winding mechanical chronograph movement that represents a significant upgrade from the previous 4130. This movement features the Chronergy escapement, Paraflex shock absorbers, and a paramagnetic blue Parachrom hairspring, providing a power reserve of approximately 72 hours and a precision of -2/+2 seconds per day. The watch offers professional timing complications, including a central chronograph seconds hand, a 30-minute counter at 3 o’clock, and a 12-hour counter at 9 o’clock. The screw-down Triplock winding crown and chronograph pushers ensure a water resistance of 100 meters.
General reviews of the 126505-0001 often praise the aesthetic harmony between the deep black dial and the warm Everose gold construction. Collectors frequently note the refined updates of the new generation, such as the slightly slimmer case profile and the thinner rings surrounding the sub-dials, which contribute to a more balanced and modern appearance. The caliber 4131 is highly regarded for its reliability and its decorative finishes, including the Rolex Cotes de Geneve. While the watch is celebrated for its prestige and investment potential, common criticisms typically center on the high retail price and the limited availability at authorized dealers due to extreme global demand.
