Patek Philippe. A fine and rare 18K pink gold annual calendar automatic wristwatch with sweep centre seconds, moon phases and power reserve

With Patek Philippe Extract from the Archives confirming production of the present watch with cream dial, 3 Arabic numerals and baton-cut indexes in white gold, luminescent coating, English version in 2009 and its subsequent sale on 5 May 2009.

To the best of our knowledge, this watch has never been offered in public before.

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.

The present example of reference 5146 bears calibre 324/999. While this model featured at its launch the calibre 315/999, an updated version of the movement was introduced in 2008. This specific example is intriguing because it bears the new calibre, but still stamped with the Geneva Seal.The Patek Philippe Seal, introduced in 2010, is usually found on these movements. Only the 324/999 movements made in the first two years from the release of the calibre (2008-2009) bear the traditional Poinçon de Geneve.
