Patek Philippe World Time
  THE FACE OF THE PATEK PHILIPPE WORLD TIME wATCH is organized in three parts. The hour and minute hands indicate the local time on the central dial. Around it are two concentric rings. The inner ring is subdivided into twenty-four am/pm hours, and the outer one bears the names of cities that represent each of the twenty-four time zones. These two rings allow simultaneous reading of the current time in any time zone without any adjustments whatsoever. The numbers from 1 to 24 opposite any city name show the current hour in the respective time zone. The minutes are indicated by the minute hand. At the 12 o’clock position, the inner ring with the day/night contrast shows the same local time displayed by the hands.
When the watch is set for the very first time or after the movement has stopped, the city on the outer ring as well as the local time on the 24-hour ring must be set to coincide with the 12 o’clock reference position.
If, for example, the owner is currently in Geneva (Paris time zone) and the local time is 8 am, the push button at 10 o’clock must be pressed repeatedly until the name Paris reaches the 12 o’clock position. Then, using the crown, the hands need to be set to 8 o’clock. This adjustment causes the 24-hour ring to rotate as well; the owner must make sure that the numeral 8 (am) and not 20 (pm) is aligned with the name Paris. Once this setting is made, the crown is no longer needed for adjustments, and should be pushed in firmly.
As long as the owner does not leave the time zone, the setting of the city ring does not need to be changed, and the 24-hour ring will complete one full counter clockwise rotation per day. Thus, the owner in Geneva who needs to contact someone in another time zone can see at a glance whether it is an opportune time to call.
 
 
   
Audemars Piguet Metropolis
In 2000, Audemars Piguet developed the Metropolis specifically for world travelers. This timepiece provides local time in all twenty-four time zones directly, with no need to count or calculate. Metropolis is the first wristwatch ever to include both a perpetual calendar and universal time.
Local time in the leading center of each of the twenty-four time zones appears on the subdial at 6 o’clock. Calibrated on twenty-four hours, with nighttime hours identified by their blue background, synchronized with the movement, the watch’s center disc instantly provides the local time of the twenty-four cities featured on the watch.
