Cosmograph Daytona 126505 (Everose Gold)

Rolex Cosmograph Daytona 126505 (Everose Gold)

The Rolex Cosmograph Daytona Ref. 126505 is the full 18K Everose gold expression of Rolex's legendary chronograph, originally developed for professional racing drivers and now celebrated as one of the most coveted watches in the world. Launched at Watches & Wonders 2023, this reference pairs Rolex's proprietary Everose gold alloy, prized for its enduring warm hue, with the latest generation Daytona architecture, solidifying its status as a cornerstone of the modern collection.

The watch features a 40 mm Oyster case crafted entirely from 18K Everose gold, with a fixed bezel in matching Everose gold engraved with the iconic tachymetric scale, allowing the wearer to calculate average speeds up to 400 units per hour. The dial, available in multiple configurations including black, sundust, and chocolate, features three chronograph counters: a small seconds subdial at 6 o'clock, a 30-minute counter at 3 o'clock, and a 12-hour counter at 9 o'clock, all enhanced with Chromalight luminescence for legibility in low-light conditions.

The case construction includes a screw-down Triplock crown and screw-down chronograph pushers, scratch-resistant sapphire crystal, and a solid caseback, providing a water resistance of 100 meters (330 feet). The screw-down pushers ensure water resistance is maintained even during timing operations.

Powering the watch is the Rolex Calibre 4131, a fully in-house automatic chronograph movement. It operates at 28,800 vibrations per hour (4 Hz), delivering hours, minutes, seconds, and chronograph functions. The movement features a column wheel and vertical clutch mechanism for instantaneous, precise chronograph engagement, the Chronergy escapement for enhanced efficiency and magnetic resistance, a paramagnetic blue Parachrom hairspring, and Paraflex shock absorbers, providing a power reserve of approximately 72 hours. It is certified as a Superlative Chronometer, guaranteeing precision of −2/+2 seconds per day after casing.

The watch is fitted with the Oyster bracelet in 18K Everose gold, secured by a folding Oysterlock safety clasp with the Easylink 5 mm comfort extension system.
