The Rolex Cosmograph Daytona reference 116578SACO is a rare, high-jewelry variation of the iconic Daytona, distinguished by its vibrant orange sapphire-set bezel.
In Rolex nomenclature, the “SACO” suffix indicates the bezel configuration: SA refers to saphir (sapphire) and CO refers to cognac or orange-hued stones.

Aesthetic & Collectibility
The 116578SACO is celebrated for its warm, monochromatic aesthetic. While standard gold Daytonas are utilitarian, this reference transforms the watch into a piece of jewelry. The orange sapphires are meticulously color-matched to complement the 18k yellow gold case, while the Mother-of-Pearl dial adds an organic, iridescent quality that changes appearance depending on the lighting.
It is considered a highly exclusive reference, often sought by collectors who appreciate the rarity of factory-set gemstone models over standard production pieces.
