Cosmograph Daytona Everose - Cerachrom / Chocolate / Oysterflex

Ref. 126515LN-0010

The Rolex Cosmograph Daytona 126515LN-0010 was introduced in 2025 and is presented in an Oyster case measuring 40 mm in 18 ct Everose gold. The case is paired with a black monobloc Cerachrom bezel in ceramic, engraved with a tachymetric scale for measuring average speeds. The screw-down winding crown and pushers contribute to a water resistance rating of 100 metres. The dial is executed in a bright chocolate and black colour scheme, featuring snailed chronograph counters. Applied 18 ct gold hour markers and hands are filled with Chromalight luminescent material for legibility in low-light conditions. The chronograph display comprises a central chronograph seconds hand, a 30-minute counter at 3 o’clock, a 12-hour counter at 9 o’clock, and a small seconds indication at 6 o’clock. Powering the watch is the self-winding Rolex calibre 4131, a mechanical chronograph movement operating at 28,800 vibrations per hour. It provides an approximate power reserve of 72 hours and features a paramagnetic blue Parachrom hairspring and Paraflex shock absorbers. The movement is certified as a Superlative Chronometer following casing. 126515LN-0010 is fitted with an Oysterflex bracelet, constructed from flexible metal blades overmoulded with black elastomer. The bracelet is secured by an Everose gold Oysterlock folding clasp and incorporates the Rolex Glidelock extension system for fine adjustment.
