Rolex Cosmograph Daytona Oyster, 40 Mm, Platinum Ref: M126506-0001

Rolex Daytona Cosmograph with Ice-Blue Dial

Ice-Blue Dial

• Features: The watch showcases an ice-blue dial with snailed chronograph counters, 18 ct gold applique hour markers, and hands. It includes a Chromalight display, known for its highly legible luminescent material.
• Functions:
  • Central Sweep Seconds Hand: Allows precise reading of 1/8 second.
  • Counters: Two counters on the dial display elapsed time in hours and minutes, aiding drivers in mapping out track times and tactics accurately.

Tachymetric Scale

• Bezel: The monobloc Cerachrom bezel features a tachymetric scale for measuring average speeds up to 400 miles or kilometers per hour.
• Advantages:
  • Material: Made of high-tech ceramic, the bezel is corrosion-resistant, virtually scratchproof, and unaffected by UV rays.
  • Legibility: The tachymetric scale is exceptionally legible, thanks to the deposition of a thin layer of platinum via PVD (Physical Vapour Deposition) process. The bezel is crafted in a single piece, ensuring waterproofness.

Platinum

• Characteristics: Platinum, known for its silvery whiteness and vibrant luminosity, is among the densest and heaviest metals, offering exceptional corrosion resistance. Rolex uses 950 platinum, an alloy with 950‰ purity, carefully crafted in-house.
• Properties: Despite its density, platinum is soft, elastic, and highly malleable, making its machining and polishing complex.

Oyster Bracelet

• Design: The Oyster bracelet is a robust and comfortable metal bracelet with broad, flat three-piece links. Introduced in the late 1930s, it remains a hallmark of the Oyster collection.
• Production: Combining advanced technology and aesthetic controls, the bracelet embodies the perfect balance of form and function.

4131 Movement

• Calibre: The new-generation calibre 4131 is a chronograph movement developed and manufactured by Rolex.
• Performance:
  • Chronograph Function: Features a reduced number of components, enhancing reliability.
  • Mechanism: Equipped with a column wheel and vertical clutch for precise and instantaneous start.
  • Decoration: The bridges feature Rolex Côtes de Genève with a polished groove between each band.
• Case Back: The 950 platinum case includes a transparent sapphire case back with an anti-reflective coating, showcasing the movement’s decorations and the oscillating weight, made of 18 ct yellow gold.
