Welcome to SwissWatchExpo, and the GMT function of the Rolex series of watches.
Now we have three different generations of watches here.
The one on the far right, is the GMT Master, not the Master II.
You can tell because when you look at that little portion of the dial, it says GMT Master.
Now this, is a GMT Master II.
See how it says Master II on the dial, this is also the most updated version of the GMT
Master II, because it has the same functionality as this watch.
So these two watches are similar in how they function, but drastically different than how
they look.
This has the painted bezel, the tapered lugs, they're both 40 millimeters, but this one
has the ceramic bezel.
This is called a Batman because it's black and blue on the top and the bottom.
And then it has the wider lug series, not the tapered lugs series.
This one also happens to have a Jubilee bracelet, but they also come in the Oyster bracelet,
like the one in this one.
So these look very, very different.
However, they are the same width and they function the same different era.
This is an earlier 2000s model, and this is a present day late 2010s model.
So this one happens to actually be unworn.
It has some of the protective stickers on it.
The original owner was able to leave them on there.
So that's kind of surprising, but here's what we need to do.
We need to display the functionality in the differences between these two watches.
These are similar watches.
They look exactly the same.
They're both 40 millimeters.
They in all respects, unless you look at the dial, you probably wouldn't notice the difference
between the two, but the movements function differently.
Now here's what the most important thing is about this particular watch.
This is the GMT master I.
You see that?
No Roman numeral two indicator.
This watch the GMT hand is in synchronous time with the hour hand, what we would consider
local time, right?
So it, when you unscrew the crown, this is a water resistant watch.
You can wear it in the water.
You're going to pull this out to set the time we're going to pull that out.
Two clicks all the way up to the edge.
We're going to move that our hand around the dial.
Now, see, it says, it's the 23rd.
Now, how do we know that this is midnight?
I know this is midnight because now the GMT hand is at the top of the bezel.
I'm going to turn this bezel around to mark the exact so that it doesn't look confusing.
It's exactly symmetrical with the triangle.
For the 12.
When I do this, you see it changed the 24th from the 23rd.
We know that's midnight, no question.
Now I want to be clear, never set that date any time those hands are above the nine and
the 3:00 AM mark.
So the 9:00 PM and 3:00 AM, because you can crash the date wheel.
You can bend it, break it.
It may not change on time.
It may change slowly.
It may not at all.
Definitely don't want to do that.
So you always want to set the time when the hour hand is in the bottom portion of the
dial.
Now we know that's midnight, cause it just flipped.
I'm going to put this at 6:00 AM, but you may notice see that 6:00 AM.
Your GMT hand is at 6:00 AM.
Why that GMT hand goes around this outside bezel only one time per day.
Whereas this hour hand goes around the inner dial two times per day.
You with me so far.
So watch this GMT hand.
This is 6:00 AM.
Now it's noon.
How do we know?
Because this GMT hand, when that triangle is properly aligned is showing that it's noon.
See that it's 12.
Now watch this noon.
We're going to go to 6:00 PM.
Now don't pay attention.
We're at 6:00 PM.
Don't pay attention to that bezel because that's your local time.
That's 6:00 PM.
How do we know?
Well, when these are properly aligned, the GMT hand is pointing at the 1800 Mark.
That's 18 hours out of a 24 hour day.
That's 6:00 PM.
Making sense now.
Okay, well now you're going to say to yourself, well, what if I want to know at different
times on, I don't understand how this tells me a different time zone.
If this one and this one are in sync.
Well, that's a very good question.
What you actually do on this model is you move that bezel forward or backwards, depending
on what, how many hours you need to add or subtract.
So in other words, if your local time is here, you're going to add or subtract how many hours
you need to measure the time zone, where you're going, right?
So if you need to, you have 1800 hours, it's here and you need to go up three hours.
So 18, 1920, 21 that's nine o'clock.
You will move three hours ahead to nine o'clock.
And now your GMT hand is pointing to whatever time zone you're in add or subtract three
hours depending.
So you can subtract three hours.
You see that let's subtracting three hours.
You can subtract three hours.
So one, two, three hours.
You see that.
So now you're at five o'clock, four o'clock three.
O'clock see, because you subtracted three hours.
Does it make sense?
So 14:00 hours is 13:00.
I'm sorry, 15:00.
I was trying to go backwards.
14:00, 15:00 16:00.
Makes sense.
Two o'clock, three o'clock, four o'clock, five o'clock, six o'clock you see that?
A little bit complicated.
I know you probably don't do that every day, but in order to set the time and the date
always remember our hands in the bottom half of the dial.
That's the safety zone.
If you need to set the date to simply pull it out, one click roll the day, set the date,
whatever date you needed to be pushing the crown, screw it down.
Push in, screwed down.
Okay.
A little bit lengthy explanation on that one, but that's because that one's more complicated
to understand than this one.
This one's easy to understand this one.
Same thing, unscrew the crown a little bit different though.
The date flips using the hour hand alone, because it independently operates from the
GMT hand.
Watch this.
So it's the 12th we've picked this watch up.
We don't know if that's am or PM what we're going to find out because I'm going to pull
this crown all the way out.
Like I'm going to set the time and see, see how that that's also going around this outside
bezel one time per day.
But the inner one is chasing it quickly because it goes around two times per day.
Now watch see that that date set at 30 went to 13 from 12 that's because our, our hand,
our local, our hand past the 12 and it set to midnight.
So that's how we know now that this is 6:00 AM.
Only because we indicated it by the date flip, but watch this.
So would, this is noon, right?
This is in synchronicity because it shows noon on the bezel.
But watch, I'm going to push this all the way back in, pull it out one click.
Now, watch this, see that I'm only adjusting my local time.
So let's say I went from one time zone to the next and I wanted to set my local time.
But my home time is still noon.
Now I can set my independent time to whatever time zone I'm in.
So if I was in, if it was noon now see how that flipped to 14.
That's midnight, right?
So this is at noon.
This is in synchronicity.
So I want to make sure that I keep my home time at noon.
Now I'm going to say, well, because it's in synchronicity here.
I'm going to move this one to three.
I'm at three o'clock local time.
See that it's noon back home, but it's three o'clock local time.
Well it's noon back home.
And let's say I'm in California.
I can go back.
One, two, three, it's nine o'clock local time.
Now am not PM.
So it's 9:00 AM.
Still registering noon back home because the GMT hand is pointing it outside bezel.
Whereas the hour hand local's pointing to your inner bring on your dial, just like you
normally would tell time, because that's your local time.
I'm hoping that that makes sense.
I'm hoping that's the easy explanation.
So, uh, just to be clear, that's how you set the local time versus your GMT time.
But also if you want to set your day, you can go forward, see how it changed to 1516.
If you need to go backwards, you can do that to 15, 14, 13.
Every time you pass midnight, it goes back one.
So now we're sending back at 9:00 AM on the 13th.
So that's how that works differently from so GMT master GMT master II.
Now, this Watch works exactly the same modern day.
Watch unscrew the crown.
So right now we don't know.
We have no idea what time this watch is telling us that it is.
We don't know if that's almost 10:00 AM or almost 10:00 PM.
So we're on the screw in the crown and I'm going to pull it out.
Some recent history watch.
So I'm having a little bit of time.
My fingernails are terrible.
Um, I pulled all the way out.
Same thing, two clicks.
I'm going to run that our hand because we don't know actually I'm going to wind the
watch first.
That's a good idea, right?
One the watch real good first and make sure it's running properly
And pull that out.
I'm going to run that our hand past the 12 and see if that date flips.
Boom, the date flip for 11 to 12.
That means it's midnight.
Put that our hand in the bottom half of the dial.
Now let's say I'm going to do this.
I'm going to make this easy because I really want you all to understand how this works.
I'm going to put this at noon and actually we're going to set the local time to noon.
So I'm not paying attention to this.
I'm paying attention to this because this GMT hand is pointing to the outside edge of
the bezel.
And I want it to be noon.
This is straight up and down.
Everything's aligned.
I want it to be noon.
So I'm going to move all hands.
I'm only paying attention to this hand and that one now it's noon.
Wherever our local time is indicates that it's one o'clock in the afternoon.
See how we can move the hour hand independently now.
So what if we advance it three hours?
Now it's three o'clock.
If we're on West coast time, we moved the local hand to nine o'clock.
Now it's 9:00 AM.
So 3:00 AM.
I'm sorry.
3:00 PM. 9:00 AM.
Now let's say you're on the other side of the world.
Well, now it's 9:00 PM.
You see that because if you go past the 12, it's changed the 13.
So now you're that far out.
I hope that makes sense.

We'll do everything we can to help you.
These are great watches, although they may be a little bit complicated.
Remember this.
You can also change time zones with your bezel too.
That's a little bit more of a complicated understanding.
So if you have any questions about it, definitely call us.
