Rolex Cosmograph Daytona 40mm White Gold Bright Blue Dial Oyster Bracelet - 126509 - 2025

Radiant Precision in White Gold: The Cosmograph Daytona

An emblem of Rolex’s uncompromising commitment to excellence, this 40mm Cosmograph Daytona is a striking blend of sporty sophistication and horological mastery. Crafted entirely in 18K white gold, the robust Oyster case is equipped with a screw-down case back and crown, enhanced by the Triplock triple waterproofness system—ensuring enduring strength beneath its elegant exterior.

Framing the vibrant bright blue dial is a fixed tachymetric bezel, also forged in 18K white gold, designed for precise speed measurements—a hallmark of the Daytona’s racing legacy. The luminous hour markers and hands offer optimal legibility, while the sub-dials at 3, 6, and 9 o’clock provide chronograph functionality with Rolex’s signature clarity and balance.

At the heart of this timepiece lies the Rolex Manufacture Calibre 4131—an automatic chronograph movement offering precision of -2/+2 seconds per day and a power reserve of approximately 72 hours. Equipped with a paramagnetic blue Parachrom hairspring and Paraflex shock absorbers, the movement delivers high resistance to shocks and magnetic fields, ensuring robust performance in all conditions.

Completing the design is the iconic three-link Oyster bracelet in solid 18K white gold, secured by a folding Oysterlock safety clasp and the Easylink 5mm comfort extension system—for seamless adjustment and all-day comfort. Waterproof to 100 meters (330 feet), this Daytona is as reliable as it is refined.
