Description

Horological magnificence is embodied in the Rolex Cosmograph Daytona Reference 126599TSA “Blue Sapphire,” an off-catalog timepiece that was quietly unveiled at Watches & Wonders 2025. The watch is meticulously crafted from 18K white gold, which provides a pristine canvas for the extraordinary gem-setting that follows.

The bezel is adorned with 36 baguette-cut blue sapphires with each gemstone individually selected and precisely set by master jewelers. The lugs and case sides are embellished with 54 brilliant-cut diamonds, which are strategically positioned to enhance the watch’s silhouette and capture light from every angle. As such, this Daytona represents the pinnacle of Rolex’s gem-setting expertise.

A silver sheen obsidian dial is employed as the foundation for this masterpiece, where the natural properties of this volcanic glass create subtle iridescent reflections that change with viewing angles. The hour markers are fashioned from matching blue sapphires, establishing perfect harmony with the bezel.

Technical excellence is preserved beneath the opulent exterior, where Rolex’s latest-generation chronograph movement delivers precision timekeeping with a substantial power reserve. This extraordinary watch stands as a testament to Rolex’s ability to create timepieces of breathtaking beauty and artistry while maintaining the functional integrity that has defined the Daytona collection since its inception.

Production of this off-catalog Daytona is extremely limited, ensuring that this exceptional timepiece will be acquired by only the most discerning collectors.
