In 1988, Rolex celebrated the 25th anniversary of the highly coveted Daytona with the launch of reference 16520 in stainless steel, ref. 16523 in two-tone steel and gold, as well as the luxurious 18 karat yellow gold ref. 16528. Housed inside this highly sought-after chronograph is the famous Cal. 4030, the Zenith El Primero movement modified by Rolex, and was the most reliable and robust self-winding chronograph movement during that era.

The present example in yellow gold features the coveted floating placement of the “Cosmograph” designation on the dial with an inverted six in the subdial at 6 o’clock. Produced for only one year from 1988 until 1990, this remarkable variant can only be found on examples bearing an “R” or “L” serial number. Part of the L series, the present specimen is also fitted with the period correct Mark 1 bezel with 200 units scale and unit per hour text at 3 o’clock mark. Highly collectible with incredible rarity, the connoisseurs with keen attention to details will notice an interesting feature on the dial.
