Details & Specifications
Description:
The Rolex Cosmograph Daytona ref. 126503 in Oystersteel and 18ct yellow gold (Rolesor), with a black dial. This example dates from 2025 and comes with its box and papers.
The 40mm Oyster case is paired with a polished 18ct yellow gold bezel engraved with the tachymetric scale, and the Oyster bracelet combines Oystersteel outer links with yellow gold centre links. The black dial carries luminous baton hour markers, with yellow gold subdial rings and chronograph hands that echo the bezel and bracelet. The result is a classic two-tone Daytona that remains one of the most recognisable combinations in the Rolex range.
Inside is the in-house Calibre 4131, a self-winding chronograph movement with a column wheel and vertical clutch, offering approximately 72 hours of power reserve. The watch is water resistant to 100 metres and is fitted with the Oysterlock folding safety clasp with Easylink 5mm comfort extension.
