In 2000, Rolex introduced the groundbreaking Cosmograph Daytona ref. 116520, featuring the firm’s first ever in-house self-winding chronograph caliber 4130, replacing its former Zenith El Primero based caliber 4030. Entering into the new millennium with a bang, Rolex also introduced gold variants of the Cosmograph Daytona, and also for the first time were also offered with various dial materials, including hardstones. Rolex has always been at the innovative forefront when it comes to the experimentation of dial materials. Hardstone dials have always been a collector's favorite due to the fact that every dial is unique as it is natural. Various hardstones have differing natures, in terms of composition, luster and hardness, hence executing hardstone dials require extreme precision to execute.

This beautiful white gold Daytona is fitted with an incredibly attractive and rare rubellite dial with diamond-set numerals. The textured effect of the rubellite adds flair, movement and intrigue to the dial layout, and furthermore provides a perfect canvas for the diamond-set numerals to shine on. Moreover, most interestingly, the reference number is designated as reference 116509H - research suggests that the "H" refers to a non standard dial such as the present watch.
