Bicolour Datejust model 16013 from December 1980 with black / baton dial and Jubilee bracelet. This is the older, plastic glass version on which you turn the crown backwards to change the date. Comes with original UK papers, our own presentation box & warranty card, and has had a full movement service in February 2010. The keen price reflects the amount of wear visible to the bracelet; we would advise that this should be worn as a dress watch rather than a hard-working watch. The NEW equivalent is now £5,580 !!
