Rolex Daytona Ref. 16528 , 18k Yellow Gold, Zenith Movement, Diamond Dial

The Rolex Daytona Reference 16528 holds a pivotal place in the history of the Cosmograph: it was the first Daytona to be powered by an automatic movement, marking Rolex's transition from the hand-wound Valjoux era to a new generation of self-winding chronographs. Introduced in 1988, it houses the Rolex Cal. 4030 , a heavily modified version of the legendary Zenith El Primero , and was produced until 2000, when Rolex replaced it with the in-house Cal. 4130. The Zenith-era Daytona is now universally regarded as the most collectable iteration of the reference. KEY SPECIFICATIONS: Reference: 16528 Year: 1991 Case: 18k Yellow gold, 40 mm Dial: Black with diamond hour indices Movement: Automatic, Zenith El Primero Cal. 4030, 31 jewels Bracelet/Strap: 18k Yellow gold Oyster bracelet Accessories: Watch only , accompanied by 2-year warranty COLLECTOR'S NOTE The 16528 in yellow gold with a diamond-index dial is among the most desirable configurations within the Zenith Daytona family. Its luxurious aesthetic, combined with the historical significance of the El Primero movement , discontinued by Rolex in 2000 , makes it a cornerstone piece for any serious collection. Early examples from 1988 to the early 1990s may feature the coveted "inverted 6" on the dial, a printing quirk that commands a significant premium. The yellow gold case and bracelet, often found polished, make an unpolished or lightly worn example particularly rare.
