Bicolour Oysterquartz Datejust model 17013 in SUPERB condition, having just had £790 spent on it at Rolex UK, where it received a full service and new dial. Comes with original boxes, the two-year Rolex UK service warranty ( expires April 2014 ) and a photocopy of the original instructions, helpfully supplied to us by Rolex. Not many people realise that Rolex DID make quartz watches like this until a few years ago, but they all have the same tell-tale, loudly-ticking second hand. Available from Miltons of Church St in Liverpool city centre.
