Since its launch in 1963, Cosmograph Daytona has been one of the most sought-after watches by aficionados, connoisseurs and collectors. As a timeless watchmaker, the success of this British-found company can be attributed to the bold innovations that positioned the manufacture as the most recognized luxury brand and a unique one among its competitors. Not only did they introduce the world’s first water-and dust-proof “Oyster” case, but also many daring designs of wristwatches that are defining in the history of haute horology. Some striking examples include the Daytona Beach reference 116519 and the present example - the Cosmograph Daytona Rainbow reference 116598 RBOW. 

The yellow gold and white gold Rainbow Daytona debuted in 2012, followed by the Everose Gold edition reference 116595 RBOW in 2018. Embellished with multi-color baguette-cut sapphires around the bezel, each gemstone is carefully handpicked and handcrafted to resemble an array of rainbow hues. Pushing the design limit of a wristwatch, the lugs and crown guards are elegantly set with brilliant-cut diamonds. Set against a gleaming black dial and gold meteorite sub-dials, the hour markers are finished off with 8 other diamonds to further the sumptuousness and brilliancy of this one-of-a-kind timepiece.
