SIGNED ROLEX, OYSTER PERPETUAL, COSMOGRAPH DAYTONA MODEL, REF. 16528, CASE NO. L235978, CIRCA 1989

In 1988, Rolex introduced their first ever automatic chronograph wristwatch as the 16500 series fitted with Calibre 4030. An early example of this series, the reference 16528, features a very attractive “Four Line” dial with an inverted six to the hour subsidiary dial on the chronograph and was referred to as the MK 2 dial. Further distinguished by its early MK 1 bezel, the present watch was calibrated for 200 instead of 400 units per hour.
