Its mechanism for the permanent display of all 24 time zones and its truly convenient adjust-ability to any local time constitute a technical coup that will appeal to all who admire useful complications. In turn, its cloisonné enamel dial will delight connoisseurs of the art of enamelling.

Patek Philippe’s World Time watches belong to the category of so-called useful complications. They serve their owners well with practical functions of relevance in contemporary everyday life. At a glance, a World Time watch indicates the hour at all major international stock markets: Frankfurt, London, New York, Tokyo, Hong Kong, and Bangkok.

Now, switching from one time zone to another is accomplished simply by pressing the button at 10 o’clock. Every time it is pressed, the hour hand will advance by one hour while the city ring and the 24-hour ring will rotate counter-clockwise by one hour (equivalent to one time zone).

This mechanism was devised by the gifted Geneva watchmaker Louis Cottier in the early 1930s. He offered his invention to Patek Philippe in 1959, Subsequently, Cottier created another mechanism for Patek which was able to display two time zones simultaneously and ultimately inspired the development of the Calatrava Travel Time Ref 5134.
