Rolex Cosmograph Daytona "Rainbow" (Yellow Gold / Black Dial)

A highly prized, ultra-luxury edition of the classic racing chronograph executed in solid 18-karat yellow gold. The iconic tachymeter scale is replaced by a bezel set with a striking gradient of 36 baguette-cut sapphires reflecting a vibrant rainbow spectrum. The watch features brilliant-cut diamond-set case lugs and crown guards, framing a black dial decorated with diamond hour markers and unique, textured gold crystal sub-dials.
