Bicolour Daytona Cosmograph model 16523 with white dial on Oysterlock 78393 bracelet. This watch is a U158xxx case number model from around 1997 and contains the famous Zenith-based Rolex 4030 calibre movement. It comes with original, large Rolex box-set, Cosmograph booklet, swing-tag and undated UK papers from J J Rudell & Co in Wolverhampton. Priced keenly as the bezel and dial are slightly showing their age, but this is still a very good example and especially desirable because of what comes with it. The NEW equivalent is now £11,250 !
