The Rolex Oyster Perpetual Cosmograph Daytona reference 116503 combines a 40 mm Yellow Rolesor case with a naturally patterned mother-of-pearl dial, diamond-set hour markers, an engraved yellow-gold tachymetric bezel and a three-piece Oyster bracelet. Powered by the self-winding calibre 4130, this configuration brings refined precious materials to the collection’s performance-focused chronograph architecture.
The Cosmograph Daytona was developed around the measurement of elapsed time and average speed. Its three-register dial, central chronograph hand, screw-down pushers and engraved tachymetric bezel form a clear and purpose-driven chronograph display.
This reference is presented in Yellow Rolesor, combining Oystersteel with 18 ct yellow gold across the case, bracelet, winding crown, chronograph pushers and bezel. The contrasting metals create a balanced transition between polished precious-metal surfaces and robust steel construction.
The mother-of-pearl dial gives the watch its defining visual character. Its naturally formed surface produces changing reflections and subtle variations in tone, while diamond-set hour markers introduce precise points of light around the chronograph display.
Three subsidiary counters organize the timing functions, displaying running seconds, elapsed minutes and elapsed hours. The engraved tachymetric scale can be used with the central chronograph hand to calculate average speed over a measured distance.

The fixed 18 ct yellow-gold bezel carries an engraved tachymetric scale designed for calculating average speed over a measured distance.
The self-winding mechanical chronograph movement uses bidirectional winding through a Perpetual rotor and provides an approximate 72-hour power reserve.
Screw-down pushers control the central chronograph hand and the elapsed-minute and elapsed-hour counters through a precise integrated timing mechanism.
A scratch-resistant sapphire crystal protects the mother-of-pearl dial and preserves a clear view of its diamond markers and three chronograph counters.
The three-piece bracelet combines Oystersteel outer links with polished 18 ct yellow-gold centre links and is secured by a folding Oysterlock safety clasp.
