Price Upon Request

Patek Philippe’s World Time pocket watches, particularly reference 605 with cloisonné enamel dials, rank among the most celebrated creations of the post-war era, uniting mechanical ingenuity with artistic mastery.
Introduced in 1937 and based on Louis Cottier’s groundbreaking world time system, the 605HU (“Heures Universelles”) allowed the simultaneous reading of multiple time zones. Produced until the late 1940s, it was offered with metal dials or, in the most coveted examples, vivid cloisonné enamel maps—each unique, crafted with fine gold partitions and fired for depth and brilliance that endures today.
The present watch, made in 1948, displays both London and Paris under Greenwich Mean Time, a detail tied to the shifting time zones of post-war Europe. Its enamel dial depicting North America and a palm tree is one of only four known, underscoring its exceptional rarity.
A union of artistry, history, and technical vision, this 605HU remains one of the most desirable and poetic expressions of Patek Philippe’s world time legacy.
