Patek's World Time watches features a rotating ring with the names of 24 cities inscribed on it. A second rotating ring has 24-hour markers. This is used to display time in different time zones. Local time is told by a standard hour and minute hand. Mechanically it has a self-winding movement.

The system works this way. If you look at the picture on top, the City of London is on top of the small red triangle. It means that the hour and minutes hands are representing the time in London. From the hour and minutes, the time is 10:07 a.m. If the time were 10:07 p.m. the number under the red arrow would be 22.

From the outer dial, you can check the times in different time zones. Under the label New York, the number displayed is 5, meaning that it is 5:07 a.m. in New York. Under the name Moscow, you see the number 13, meaning that it is 13:07 hours, or 1:07 p.m., in Moscow. In this way, the Ref. 5131 shows the time around the world in a glance.

The easiest to explain how this all works is to pretend we are setting the watch for the first time. If the user is based in London, the button at the 10 o'clock position should be pressed until the name of London appears at 10 o'clock. Each time the button is pressed the outer ring with the names of the cities moves one city at a time counter clockwise.

When the correct city (in this case London) is at the 12 o'clock, pull out the crown and adjust the hour and minute hands as you would a conventional watch. Lets say the time is now 10:00 am. Set the hands so that the hour hand points to the ten o'clock position. The inner ring would move so that the number 10 is located right below the name London, which means the watch is set to 10:00 a.m.

Reset the crown and the watch starts to run. How about Moscow, what time is it there? Under the name Moscow the number on the ring is 13, meaning 1300 hours or 1:00 p.m.

After an hour, the hour hand would advance once hour to read 11 o'clock. The inner ring would rotate counter clockwise so that the number 11 would be under the name London, meaning 1100 hours or 11 o'clock in the morning. Under the name Moscow, the number would now be 14, meaning 2:00 p.m.
