Description of the Watch

This unisex chronograph is ideal for collectors who appreciate elite materials and flawless execution.

Overview

Introduced in 2023, this version of the Cosmograph Daytona continues the legacy of Rolex’s legendary chronograph—originally created for professional race car drivers. With a bold presence and exceptional versatility, it’s as suitable for daily wear as it is for formal occasions. The use of a high-tech Cerachrom bezel and a contemporary Oysterflex bracelet further enhances its modern and luxurious character.

Design and Craftsmanship

The 40 mm Oyster case is crafted from solid 18 ct white gold, offering a luminous, durable frame. The bright black and steel dial features eight diamond-set hour markers, carefully placed to enhance symmetry and sparkle. The remaining markers are baton-style, contributing to a clean and functional look. Hands and indices are treated with Chromalight, Rolex’s proprietary luminescent material, for optimal legibility. A fixed black Cerachrom ceramic bezel with an engraved tachymetric scale completes the bold yet refined look.

Movement and Performance

At the core is the Rolex Caliber 4131—a Perpetual, mechanical chronograph, self-winding movement known for its superior reliability and accuracy. Equipped with a Chronergy escapement, Parachrom hairspring, and Paraflex shock absorbers, it resists shocks and magnetic fields, while maintaining chronograph precision. A 72-hour power reserve ensures stable performance over long intervals between wears.
