Rolex Cosmograph Daytona 126503 White Dial

The Rolex Cosmograph Daytona – Ref. 126503 blends motorsport heritage with refined luxury through its Yellow Rolesor construction, combining Oystersteel with 18 ct yellow gold. The 40 mm Oyster case is paired with a fixed yellow gold bezel engraved with the tachymetric scale, emphasizing the model’s racing DNA while delivering a sophisticated two-tone presence.

The watch features a white lacquer dial accented by champagne-colored sub-dial rings, creating a strong visual contrast. Applied yellow gold hour markers and hands filled with Chromalight luminescence ensure excellent readability in both daylight and low-light conditions. The layout preserves the Daytona’s iconic tri-compax chronograph configuration (3-6-9).

The Oyster case integrates a Triplock screw-down crown, screw-down chronograph pushers, scratch-resistant sapphire crystal, and a solid screw-down caseback, providing 100 meters of water resistance suitable for everyday wear.

Powering the watch is the in-house Rolex Calibre 4131, the updated generation of the Daytona chronograph movement. Operating at 28,800 vibrations per hour (4 Hz) with 44 jewels, it incorporates the Chronergy escapement, Parachrom hairspring, and Paraflex shock absorbers for improved efficiency and durability. The movement uses a column wheel and vertical clutch system, ensuring smooth chronograph engagement and delivering a 72-hour power reserve with Superlative Chronometer precision of −2/+2 seconds per day after casing.

The watch is fitted to the robust Rolesor Oyster bracelet with an Oysterlock safety clasp and Easylink 5 mm comfort extension, offering both durability and comfort.
