Patek Philippe Ref. 1415 World Time Enamel Dial: A Vintage Masterpiece

The Patek Philippe reference 1415 is a significant early World Time wristwatch, distinguished by its innovative mechanism for simultaneously displaying multiple time zones. It represents a key development in Patek Philippe's history of complicated watches, preceding later World Time models and establishing the brand's expertise in this horological function. The reference is notable for its integration of Louis Cottier's patented World Time system, which allowed for easy adjustment of the city ring and hour hand.

This reference was produced with a 31 mm case, available in yellow gold, rose gold, and platinum. It houses the manual-winding caliber 12''', offering a power reserve of 38 hours.
