Dual time zone watches are a handy tool for the traveler, a businessperson with an international company or a family with distant relatives. The purpose of each time setting is to help the user understand what time of day (or night) it is elsewhere.
Dual time face watches have been around since 1853, when the Tissot watch company created its first pocket watch. Tissot is a Swiss watch manufacturer that, along with many Swiss watchmakers, is regarded worldwide as a master watchmaker.
The function of having two clock faces set with different time zones on one watch was initially created for travelers who would leave their time zone yet still wanted to be aware of the time in the place they left. Once they arrived, or even before arrival, the user could set the other clock face to the time of their destination.
With the advent of a dual face watch, a traveler no longer had to do the math. If he wanted to check in, the user could simply look at his watch and know whether the family, which was three time zones away, was already in bed.
There are valuable functions in business as well. Businesspeople who have regular contacts with clients or coworkers in other parts of the country or world can set their second clock face to what time zone these contacts are in.
People whose family or friends live in other time zones may set the dual face watch to the other time zone to know when it's a good time to call. Dual face watches take the guesswork out of what time it is wherever you are.
