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. 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). Pressing the button 24 times emulates a trip around the world and a return to the point of departure. This mechanism was devised by the gifted Geneva watchmaker and tinkerer Louis Cottier in the early 1930s. He offered his invention to Patek Philippe first and in 1959, the company protected it with Swiss Patent No. 340 191. Subsequently, Cottier created another mechanism for the Geneva-based manufacture. It was able to display two time zones simultaneously and ultimately inspired the development of the Calatrava Travel Time.
