Complete with its original Rolex box and punched certificate from March 1998, this U series 16520 'Zenith' Daytona would have been amongst the last to have Tritium luminous markers before Rolex switched to Luminova (that never ages to a lovely cream tone). In superb condition, with lovely crisp lugs and even the remnants of the original holographic sticker on the case back, this 16520 is powered by the automatic 4030 'Zenith' calibre chronograph movement. A superb investment set, that will be be £30k by next year...
