Lot Essay
Offered in very good overall condition and still retaining the protective green sticker to the case back, the present reference 16528 represents a truly rare opportunity for the Rolex collector to acquire an highly attractive example of the Daytona chronograph with 'floating' Cosmograph dial - The 'floating dial' shows the designation 'Cosmograph' with a marked distance from the previous 'Superlative Chronometer' and 'Officially Certified' lines. In later dial versions the designation Cosmograph is found immediately below the other descriptive lines.
Launched in 1988, the ref. 16500 series comprised the first automatic chronographs to be introduced by Rolex, marking an end to the production of hand-wound Daytona models. The series initially used a modified Zenith El Primero movement, which was later replaced by the 4130 calibre developed in-house by Rolex. This new movement was itself based on Zenith's calibre 400 and contained about 200 modifications.
