A cherished vintage icon that represents a pivotal chapter in the Daytona’s legacy, the Rolex Cosmograph Daytona reference 16523 is a highly sought-after timepiece. This “Zenith Daytona” belongs to the first series of self-winding Daytonas, a period celebrated by collectors for its historical importance and technical innovation. The watch is meticulously crafted in Bi-Colour Rolesor, Rolex’s signature combination of resilient stainless steel and the warm, opulent glow of 18k yellow gold. The classic fixed bezel, made of yellow gold and featuring an engraved tachymeter scale, perfectly complements the watch’s distinguished aesthetic.
