Signed Rolex, Oyster Perpetual, Cosmograph, Daytona, Ref. 16528, Case No. R'984'022, Circa 1987

This attractive Rolex chronograph is one of the very first reference 16528 that were made, as denoted by the serial number R, the first letter in the new letter coded serial number system introduced by Rolex in 1987. It correctly features the early bezel calibrated to 200 units per hour, as opposed to the later one calibrated to 400 units per hour. Early examples of this reference (bearing serial number R, such as this one) are considered highly collectible timepieces, made more desirable by the diamond-set hour markers.
