How to use a GMT Watch | Rolex GMT-Master II

The Rolex GMT-Master II is one of the
hottest watches right now. The original GMT-Master hit the market in 1954 when
Pan American Airlines consulted Rolex for a solution to traveling through
multiple time zones, and needing to keep up with the accurate local time.
Conceived in the 1600s GMT, or Greenwich Mean Time, has been the standard across
the world since the 1800s. The invention of commercial air travel brought the
need for quickly knowing the time across all 24 time zones and so the GMT-Master
was born. GMT is the standard for time measurement
in the world. All 24 time zones are based off the GMT time zone in Greenwich,
London. Time zones usually have a number after them, like in the case of Eastern
Standard Time. It is often written as “EST – 5”
representing 5 hours behind GMT time. The standards of GMT were necessary for
sailors and pilots, but in the era of smartphones the GMT function can seem
somewhat antiquated. Once you know how to use it, you will see it’s a great
alternative that can deliver a lot of information at a glance. To show how to
use a GMT we’ll be using the current Rolex GMT-Master to reference 126710, and as a side note the GMT-Master II was first released in 1983, and replaced
the original GMT-Master. The GMT-Master II was the first Rolex with an independent
24-hour hand. This advancement allows you to keep accurate time while setting the
hour hand, and is now the benchmark for a true GMT complication. The benefit of the
true GMT complication, like this Rolex, is the ability to jump the hour hand while
still keeping time. With the crown in the second position the hour can move
independently from the GMT hand. This is perfect for travelers who regularly
switch between time zone. Now let’s show how to monitor 2 & 3 separate time zones,
as well as how to use the GMT function as a compass. To measure two time zones
you will first set the GMT hand to the local time, based on the 24-hour scale. In
this case 17:00 hours, and then set the hour hand to the current time on the
12-hour scale. Your watch now shows the current, local time, in both the 24-hour
and 12-hour scale. You can now use the rotating bezel to
represent your second time zone. For example, we’re in Atlanta, and it’s 5:00
p.m., but let’s say we want to keep track of what time it is in San Francisco. We
would need to rotate the bezel clockwise to lose three hours. So clockwise goes
back in time, and counterclockwise goes forward in time.
Now the GMT hand will show the 24-hour time scale of San Francisco. The GMT hand
points to 14:00, representing 2 p.m. Now to view three separate time zones you
must first set the GMT hand to GMT time, and have the hour hand set to local time.
So in the same example the GMT time is 22:00 hours, and the local Atlanta time is
5 p.m. Then you can use the bezel to represent a third time zone by rotating
the bezel, like we did previously. So to know what time it is in San Francisco we
would rotate the bezel to minus 8, since San Francisco, or Pacific Standard Time,
is 8 hours behind GMT. Now to recap, you can see the local time is 5:00 p.m., GMT
time is 22:00 hours, and using the bezel, the time in San Francisco is 14:00 or 2:00
p.m. So there you go. Three separate time zones at a glance.
It’s also worth noting that during daylight savings you would need to
account for the one hour difference. Another really cool feature of the GMT
hand is the ability to act as a compass. Now this only works if both the hour
hand and the GMT hand are set to local time, and if you’re in the Northern
hemisphere. If this is the case, then we can go ahead and lay the watch flat, and
point the hour hand toward the Sun. The GMT hand will now be pointing North.
Again, during daylight savings you will need to factor in the difference of one hour. The GMT complication can seem out of date in today’s tech age, but 65 years
later it still serves a purpose, and delivers necessary information at a
glance. It is a true tool watch, through and through. Let us know your favorite
watch with a GMT complication, and thanks for watching.

  1. Good video, always love content like this. One problem I see is: it's actually GMT -5 and not EST -5. For example: US East Coast is at GMT -5. EST -5 is the land/area where the time is 5 hrs behind US EST time which is not a standard that's used around the world, GMT is.

    I mean, you are the watch guys but I've been actively travelling for 6 years from Asia to the US and it's always GMT + or – meaning the time is always referenced using GMT (not EST as mentioned earlier in the video).

  2. Am I mistaken or is the GMT hand set to 2300 hours in the 3 time zone demonstration instead of 2200 hours as the narrator states?

  3. Much like the Blancpain Fifty Fathoms beating the Rolex Sub to market, the Glycine Airman beat the Rolex GMT to market with a GMT complication for the jet age. Nice click-bait though for Rolex fanboyz.

  4. What does it say about me that I still don't know how to use a GMT-Master II? I feel like I would just use mine as an "Egg timer."

  5. Nice watch, good video. Agree with the EST is GMT-5 comment. I disagree when you say you can “see” three time zones at once. You can see two then rotate the bezel for a third. (Which you could rotate again for a 4th and on and on. ). Instead of rotating 1,2,3, and saying yes it’s now 1400 (when it was 1700), you could also say 17 minus 3 is 14. (In your head). And yes I can do 0200 minus 3 is 2300. But I only “see” two times displayed at any one time. Pizza timer without alarm is also useful.

  6. Thank you.I’ve been using this watch for several years.And,by far.Is the best and complete explanation of all times,I’ve ever listened.

  7. Small info correction, there are approximately 38 time zones. Not 24.

    Some countries use a half hour intervals (Like India’s +5:30 hours, or Nepal +5:45). Adding up these national differences worldwide it comes to around 38 time zones, but this does change occasionally.

    ~ You also had the GMT hand set to 2300 whilst declaring 2200, but good video description nevertheless.

  8. That's a great watch and wonderful run down on features in concise way
    Unlike my effort lol

    But fun to make 🙂
