Rolex Daytona 126509-0005 40mm 4131 Movement Tungsten Alloy Watch
A substantial 40mm luxury sports chronograph inspired by the iconic racing character of the Cosmograph Daytona. Crafted from premium 904L stainless steel, the case and Oyster-style bracelet offer exceptional durability, corrosion resistance, and a refined luster, delivering a solid, substantial feel on the wrist with the unmistakable presence of a high-end sports timepiece.
The deep blue sunburst dial displays rich variations in brightness under changing light. Three chronograph subdials positioned at 3, 6, and 9 o’clock create a balanced racing layout, while red scale details and the red “DAYTONA” lettering add a dynamic contrast. Applied luminous baton markers and silver-tone hands maintain clear readability.
A fixed tachymeter bezel marked “UNITS PER HOUR” works with the chronograph to measure average speed over a known distance. Produced by RGF Factory and powered by a 4131 movement with a stated vertical-clutch and column-wheel system, this model combines functional timing, substantial construction, and refined luxury-sports styling.
