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.

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.
