Rolex Zenith Daytona Ref. 16520 retailed by Tiffany & Co.

For collectors who appreciate the turning points in horological history, the Rolex Zenith Daytona ref. 16520 sits squarely at one of them. Introduced in 1988, the 16520 marked a major evolution in the Daytona story as the first automatic chronograph from Rolex. It replaced the hand-wound calibres of earlier generations with a heavily reworked automatic movement based on Zeniths legendary El Primero, itself one of the most advanced chronograph movements of its era. This change, paired with a new 40-millimeter case size and a sapphire crystal, helped transition the Daytona from a niche tool watch into the modern sporting icon it has become.

This example carries an extra layer of appeal thanks to its Tiffany & Co signature on the dial. Dual-signed Rolex watches from this period are understood to be exceedingly rare, with very few known examples featuring the Tiffany name alongside the Rolex Cosmograph script. That subtle co-sign has long been a point of fascination in the market because it reflects a time when certain boutiques could co-brand dials at the point of sale, a practice that has since all but disappeared.

In terms of design, the watch presents with a crisp white dial that remains clean and well preserved. The dials layout and legibility reflect Rolexs enduring focus on functionality above all. Applied hour markers and contrasting black on white subdials provide clarity, while the Tiffany signature adds a hint of provenance without overwhelming the classic Daytona aesthetics. The stainless steel case wears the defined lines characteristic of the Zenith era, with screw-down pushers and crown guards giving it a purposeful, tool-oriented presence on the wrist.

Condition here is excellent with only minimal signs of wear. The case shows restrained preservation of its original angles, and the serialised Oyster bracelet remains tight with little stretch, retaining full links and a healthy profile. Its that combination of historical significance, uncommon branding, and strong condition that makes this ref. 16520 an evocative and noteworthy example of one of Rolexs watershed watches.
