With Patek Philippe Extract from the Archives confirming production of the present watch with slate-grey dial, 3 Arabic numerals and baton-cut indexes in white gold, luminous coating, English version in 2006 and its subsequent sale on 21 December 2006. Furthermore delivered with a photocopy of the Certificate of Origin stamped Gübelin, Zürich and dated 17 February 2007 and cardboard service box.
Recently serviced at Patek Philippe in Geneva, the present watch is preserved in very good overall condition.
Introduced in 2005, reference 5146 replaced reference 5035, now featuring a moon phase display instead of the 24 hour indication and a power reserve. It is fitted with the patented annual calendar mechanism. This useful complication automatically corrects the date for months with 30 and 31 days while displaying the month and the day of the week - and only requires correction once a year at the end of February.
