Patek Philippe’s World Time watch will charm any watch lover. Its mechanism has a permanent display of all 24 time zones and it adjusts to any local time promptly making it a useful complication. In turn, its cloisonné enamel dial highlights the art of enamel painting.
While a regular world timer indicates the hour in all major cities at a glance. The local time indicated by the hour and minute hands applies to the location on the city disk that is directly aligned with 12 o’clock. The crown is used to set the correct time in conjunction with the 24-hour ring, so a distinction can be made between 4 am and 4 pm.
In the Patek world timer, 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 counterclockwise by one hour (equivalent to one time zone). Pressing the button 24 times emulates a trip around the world and a return to the point of departure.
