SIGNED ROLEX, DAYTONA MODEL, REF. 16528, CASE NO. N266805, CIRCA 1991

Offered in very good overall condition and with the full set of accessories, the present timepiece represents a rare opportunity for the Rolex collector to acquire an highly attractive example of the Daytona chronograph reference 16528. What's also interesting for collectors here is the presence of an 'Inverted 6' dial - the hours register at 6 o'clock displays an upside-down 6, a trait found on some of the early dials.

Launched in 1988, the reference 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.
