Rolex Daytona White Gold — Dark Mother-Of-Pearl Roman Dial | Ref. 116509

The Cosmograph Daytona in 18ct white gold is among the most coveted configurations of Rolex's legendary chronograph, and reference 116509 with a dark mother-of-pearl Roman dial elevates this status further with a dial of extraordinary character. The deep, shifting hues of dark mother-of-pearl — ranging from near-black to iridescent midnight tones depending on the incidence of light — provide a striking backdrop for the polished Roman numeral hour indices, a pairing that lends the 40 mm case a formal opulence rarely encountered in a sports chronograph.

Reference 116509 is powered by the Rolex Calibre 4130, a self-winding column-wheel chronograph movement developed entirely in-house and introduced in 2000 to replace the earlier ebauche-based movements. The 4130 is celebrated for its vertical clutch mechanism, which eliminates the jump at the start of the chronograph and maintains timekeeping accuracy during timing operations. With a 72-hour power reserve, a Parachrom hairspring, and Superlative Chronometer certification, it represents a significant engineering achievement that positions the Daytona among the finest mechanical chronographs in production. The screwed pushers, a legacy of the Daytona's motorsport heritage, maintain water resistance to 100 metres.

The 18ct white gold case of the 116509 features the Daytona's signature tachymetric scale engraved on the bezel, rendered here in white gold rather than the ceramic used in newer references. The Oyster bracelet with its flat three-link design and concealed Oysterclasp provides a secure, comfortable fit suited to active use. For collectors who appreciate the Daytona's connection to endurance motorsport alongside an appreciation for precious materials and exceptional dial artistry, reference 116509 in dark mother-of-pearl Roman represents an outstanding and distinctive choice.
