The 40mm gents Patek Nautilus 5711/1A has gone on to become the brand's most important watch since its release in 2006 for the 30th anniversary of the model. With the most sought-after blue/black graded dial it is powered by the hand finished automatic 26‑330 S C calibre movement viewed through the exhibition case back. This pristine example of Patek's sport watch, originally purchased in the UK, is presented complete with its original polished wooden Patek box, instructions and Certificate of Origin.
