The Rolex Daytona ref. 16520 was released in 1987 as the first automatic chronograph offered by the brand. In an effort to modernise the legendary chronograph, the Valjoux 72-based manual winding movements were traded for the reliable Zenith El Primero calibre, which Rolex heavily modified to decrease its frequency back to a more relaxed 28'800 bph. The larger 40 mm case was now fitted with a matching metallic bezel and available in either gold or stainless steel. The reference 16520 remained in production until 2000, as Rolex developed the in-house calibre 4130.
Manufactured around 1991, the present yellow gold and rather early example bears the reference 16528 and is fitted with a matching bracelet. The dial bears an inverted 6 at the 6 o'clock register, a detail collectors are particularly keen on. The recently serviced timepiece stands in appealing condition, maintaining the service stickers to its case.
