Dual Time vs GMT Watches: What’s the Difference? | SwissWatchExpo

Spotlight on: Dual Time versus GMT watches. What’s the difference? For frequent travelers and globetrotters,
a watch that tells time, in more than one time zone, is incredibly useful. Just like chronographs and calendars, the
GMT and Dual Time are very practical complications. Both display the time in two time zones at
once; but use different mechanisms. So what’s the difference between a Dual
Time and GMT watch? And which one is right for you? Let’s find out. A Dual Time watch is very straightforward.
It shows the wearer two different times, at the same time. The second timezone, is usually shown on a
subdial, using a 12-hour time frame. Think of it as a dial, within your dial! Sometimes,
a dual time subdial can include both hours, and minutes. If the subdial tells time on a 12-hour scale,
it often includes a subtle AM-PM indication, so you can tell if its day or night in the
second timezone you’re monitoring. Most people would use the main dial to display
the local time, and the subdial to display their home time zone. With a Dual Time, you’ll
never be confused about the time difference again! The GMT watch also shows you two timezones
at once, but requires a little math, and some adjustment. The GMT, stands for Greenwich Mean Time, which
is the starting point, on the 24-hour scale of international timezones.  From there,
each timezone is computed ahead, or plus GMT, or behind, or minus GMT. Most GMT watches, have the traditional hour
and minute hand, to tell time on the 12-hour markers. And then another, independently adjustable
24-hour hand, usually in a color or design, that makes it stand out. In the case of the very popular, Rolex GMT-Master,
the 24-hour hand, is marked by an arrow. The second timezone is displayed on the bezel,
as you see here. The rotatable bezel, can be adjusted forward, or backward, depending
on the time difference. Due to advances in travel and technology,
it’s now more common to do business around the globe. For that purpose, one should consider
getting a World Time watch. While Dual Time and GMT watches display two
timezones at once, a World Time watch gives a quick overview of all 24 timezones worldwide. In addition to a 24-hour time display, an
outer rotating ring, displays cities across the globe. These correspond to all 24 timezones,
telling you their current time, in one glance. So, to read two timezones at once – go for
the straightforward Dual Time, or the more sophisticated GMT. To monitor time in multiple
cities – a World Time watch is your best bet. Want to learn more about watches?
