Overview
The Rolex Cosmograph Daytona ref. 126505 represents the current generation of the iconic Daytona line rendered entirely in Rolex's proprietary 18k Everose gold. Introduced in 2023, it pairs the enduring 40 mm chronograph case with the manufacture Calibre 4131, a movement developed and produced entirely in-house. Dial options spanning sundust, black, and chocolate underscore the reference's appeal to collectors who prize both horological substance and material richness.
History
The Cosmograph Daytona has been a cornerstone of Rolex's sports-watch catalogue since the 1960s, evolving through several landmark generations defined by case material, movement, and bezel construction. Precious-metal variants have long occupied the upper tier of the Daytona hierarchy, and the introduction of Rolex's own Everose gold alloy — engineered for lasting colour stability — gave those models a distinctive identity. The ref. 126505 continues that tradition, succeeding earlier Everose references and marking the line's transition to the fully in-house Cal. 4131. Its 2023 debut placed it among the most technically current expressions of the Daytona to date.
Notable points
- The 40 mm case is crafted in 18k Everose gold, Rolex's proprietary rose-gold alloy formulated to resist fading and maintain its warm hue over time.
- Calibre 4131 is a manufacture movement developed entirely by Rolex, featuring a column-wheel chronograph mechanism and a silicon Parachrom hairspring for enhanced precision and shock resistance.
- Three distinct dial references — sundust, black, and chocolate — offer meaningfully different aesthetic characters within a single reference number.
- The ref. 126505 represents the current production Daytona in Everose gold, succeeding earlier generations and reflecting Rolex's ongoing investment in in-house movement development.
- As a chronograph, the Daytona line traces its motorsport heritage directly to its origins as a tool watch designed for professional racing drivers.
