If you frequently travel or are in touch with people in a different time zone, you may encounter the problem of not knowing exactly what time it is in the other time zone. Of course, like some famous personalities, you could solve this problem by wearing two watches at the same time, or you could simply buy a Dual Time watch. With this type of timepiece, you always have two separate time zones at hand. Let's take a look at a few of the most beautiful Dual Time watches and explore the background of this special function.
The push to create standardized time
The history of Dual Time watches begins in 1876 at a small railroad station in Ireland. The Canadian railroad director and surveyor Sir Sandford Fleming was literally left out in the rain while waiting for his train to arrive. This led him to recognize the necessity for standardized time, according to which the whole world would be able to orient itself. Until then, clocks had been set locally according to the highest level of the sun. This time meant naturally varied and, logically, even between different parts of one country.
The development of the 24 time zonesFaced with this problem, Fleming joined forces with contemporaries who shared his thinking. Their proposal was based on a calculation in which the 360 degrees of the earth would be divided by the 24 hours of a day. They used the resulting value of 15 as the basis for a uniform time within a zone of 15 degrees longitude. At the International Meridian Conference in 1884, the mean solar time of the Greenwich Observatory was established as the international prime meridian. Thus, 24 time zones were created to facilitate international coordination.
Since 1972, Greenwich Mean Time (GMT) has been declared obsolete and been replaced by Coordinated Universal Time (UTC). Nevertheless, the time in Great Britain and parts of West Africa still corresponds to Greenwich Mean Time.

Dual Time vs. GMT watches: What’s the difference?
One could assume that Dual Time and GMT watches are different names for the same type of watch. In principle, this is also true, but the two variations use different mechanisms.
What is a Dual Time watch? A Dual Time watch usually displays the second time zone using a totalizer with an additional 12-hour dial. These models normally feature a day and night indicator to provide information relating to the second time zone at a glance.
GMT watches employ a bidirectional rotating bezel with a 24-hour graduation and an additional GMT hand on the main dial that points to second time set using the bezel. The best GMT watches from Watchmaster can be found here.

With a 24-hour display, Zenith avoids the need to indicate whether it is day or night time. This watch, which appears rather sporty at first sight, is in fact a precise and reliable tool.
