The history of the Patek World Time is a well know story to watch collectors the world over, as is the desirability of the cloisonné enamel dialled version. For the first time Patek has produced a version of the fabled reference in platinum on a bracelet in the form of the 5131/1P-001. The 39.5mm case size seats the dial perfectly, an outer city ring and inner hand enamelled view of the earth as seen from the North Pole. As with previous references 'Patek Philippe' and 'Geneva' are engraved on the bezel. The movement is the ever faithful self-winding calibre 240 HU with 48 hour power reserve. A contender for one of the most beautiful watches in the collection.
