Oyster Perpetual Cosmograph Daytona in 18k Yellow Gold with Diamond-Set Dial and Bezel

The Oyster Perpetual Cosmograph Daytona in 18 ct yellow gold is the epitome of luxury and precision. This model features a striking golden, diamond-set dial with contrasting counter rings, an Oysterflex bracelet, and a bezel adorned with 36 trapeze-cut diamonds, extending to the diamond-set lugs for a truly breathtaking finish.

The Oysterflex Bracelet

Engineered for durability and resilience, the 18 ct yellow gold Cosmograph Daytona, with its Cerachrom bezel, comes paired with an Oysterflex bracelet. Developed and patented by Rolex, this innovative bracelet offers the strength of a metal bracelet combined with the comfort of an elastomer strap. The bracelet features two flexible curved metal blades, overmolded with high-performance black elastomer, offering superior flexibility and wearability.

For optimal comfort, the Oysterflex bracelet includes an internal cushioning system and the secure Oysterlock safety clasp to prevent accidental opening. The bracelet is easily adjustable thanks to the Rolex Glidelock extension system, allowing wearers to tailor the fit for maximum comfort.

18 ct Yellow Gold: A Commitment to Excellence

Rolex’s expertise in crafting the finest 18 ct gold alloys is unmatched. The brand operates its own foundry, giving it control over the production of yellow, pink, and white gold alloys by carefully adjusting proportions of silver, copper, platinum, and palladium. Each alloy undergoes rigorous inspection in Rolex’s in-house laboratories to ensure the highest quality standards before being shaped into timeless masterpieces.

Golden Dial with Chronograph Counters

The golden dial of the Cosmograph Daytona features diamond-set hour markers and 18 ct gold appliqué hands, all coated with Chromalight for exceptional readability in low light. This dial is designed with racing drivers in mind, allowing them to time laps and track race strategies with precision.

Diamond-Set Bezel: Elevating a Legendary Chronograph

The bezel of this watch is set with 36 trapeze-cut diamonds, replacing the traditional tachymetric scale with a more luxurious alternative. Despite this gem-set version, the Cosmograph Daytona remains the ultimate tool for measuring time intervals and calculating average speeds, now paired with the refinement of diamonds.
