The Rolex GMT-Master II (ceramic model)

[Tools]

GMT-Master II Reference Numbers: 116710 (SS), 116713(TT), 116718(Gold)

Date of production: 2005 to present

Case Size: 40mm

Movement: 3186
(excerpt from Henk Hoving)
The cal.3186 has exactly the same features as seen on the previous cal.3185, so there is no quickset date feature added as some guessed. The main difference between these calibers is the more precise setting of the 12 positions for the 12-hourhand when switching to another timezone.

The 12 hourhand clicks into the 12 positions without any play, and very precise and smooth, as the fixed positions where the hand clicks into, were moved from the center of the movement into the driving train of the hands, this eliminates the play that the older caliber has.

This resulted into a slightly higher caliber, from 6.4mm to 6.8mm, which resulted into a slightly higher case for the new GMT Master II when compared to the older GMT Master II.

Also, in this new GMT Master is the new, own hairspring fitted, the "Parachrom Bleu". This new Rolex-patented hairspring is very easy to recognise as the spring has a very dark blue shiny color. It consists of an alloy made of Niob (most part), Hafnium and a very small ammount other metals not described. This blue color is created because the Niob oxidizes in contact with air and formes a protective layer this way.

In comparison to the regular hairsprings, this new one consists of only non-Ferro materials, and is as such completely unsensitive to magnetic fields. Another major advantage is that this new spring is much less sensitive to temperature-variations, the frequency does not vary due to differences in temperature, which results into one of the most accurate mechanical watches you can buy today...


Power Reserve:
Expected to be 48-50 hrs.

Thank you Larry, I just love that watch:thumbsup:

[nauticalmariner]

Quick question, on the shot where the clasp of the bracelet is open, my GMT says EO6 instead of EO2 and no numbers under it like yours..any need to worry?
ES

[CBG]

Mine says PJ1, and no number underneath either.

[hjhansolo]

Mine says E010

[nbs]

Mine says E09

[Big Tobacco]

I have EO5 with 15/423 underneath it. I'd think it has naught to do with the watch, but the bracelet, as I believe these bracelets can be fitted on more than 1 model of the newer Rolex line.

[hflee55]

Excellent write up as always.

[stusrt]

i asked this elsewhere - but has there been any improvements to the GMT-IIC since it was released?
I was wondering for the 116713 if there is any difference in buying a Z, M, or waiting for a V from the AD?

thanks!

[handdoc]

those letters on the bracelet indicate when the bracelet was made...there is a chart on line if you google that info

Since were talking about the new Bracelet which, I LOVE! Does, anyone know if it will fit my 16710?

Hi there

Can somone indicate how to adjust the length of the bracelet? I can't see this on the photograph. Can the lengt only be adjusted (besides the new 5mm special easy-link) by inserting or removing a whole link of the bracelet? This would be a rather rough method as this would result in big jumps of 10mm and which is too much at a time. Through this the bracelet would be either too long or too short. With the 16710 you could nicely adjust the braceletat at its clasp. The distances of the wholes were even different so that you could either remove a link or as an alternative make the bracelet by 2 wholes shorter (or longer). And the 2 methods resulted in a slight difference as 2 wholes were not the equivalent of 10mm but 9mm then 8mm and finally 6,5mm depending which combination of links vs. wholes you took. This made a very fine adjustment possible.

Back to the question: Can somone show a picture that shows that part of the bracelet resp. its closure?

Cheers Alex

[NDT III]

I don't have a photo but looking at the bracelet, all links appear to be the same size (10mm?) making it adjustable in 5mm increments using the aptly named and much appreciated "easy-link".

[Mathemagician]

The clasp does have three holes (dimples, really) for finer adjustment, in addition to the fantastically convenient easylink.

How easy is this to adjust if you don't have a spring bar tool?

Mike

[Tools]

It's pretty easy with an eyglass screwdriver or something similar.

The springbar is compressed using the slot cut in the back of the spring-bar tube

This shot shows the three adjusting holes in the clasp

[Alex49]

Thank you Tools

In the mean time I must admit that I decided to buy me the 116710. I must say that it is outstanding. The way how you can adjust the bracelet is much better than before with the 16710. The fact that you can reduce the bracelet at the 6 side to 4 remaining links is absolutely great too as you can now adjust the lenght in a way that the calsp is fully in the middle of your wrist, which was not the cas ebefore . . . And due to the fact that the backside of the watch is flatter with the 116710 th watch is much better on your arm than before.

I am most pleased.

Cheers Alex

[He Man]

excellent watch but I bit thicker than what I am used to.

[Charley_Lima]

is it stated anywhere that the GMTiiC has the triplock as per the Subs?

I haven been able to find any info on that. It was also not mentioned in Rolex's 2009 catalogue that the crown has triplock :(

In the catalogue, they only mentioned the triplock for subs and the SDDS

According to the Rolex Web Site - the 116710 has Triplock and is water resistant to 100m.

[sexner]

I think water-resistance is 100 metres not 200 Steve.

Correct.:agree:

[DRAWTOOL]

... I think it should share the Subs water resistance, due to sharing the triplock crown and a similar case...

Yeah, Why does it not? :thinking:

[Tools]

The Trip-lock crown is not the only reason that the Sub can go to extreme depths... It also has a thicker case-back that will not compress and press against the movement under the extreme pressure at depth.

The other watches with a Triplock Crown:

Daytona
Sub
GMT IIc
Sea Dweller
Deep Sea
Yachtmaster
Yachtmaster II

good info on a nice watch IMO the best of Rolex line.

Good info

[Joe750]

Dumb question, but info I haven't been able to find - is the calendar on a GMT IIc perpatual (meaning it knows days with 30, 31, or 28 days? Always wondered. Rolex website doesn't say...

No... Perpetual, for Rolex, means that the watch will run perpetually because it is self winding..

It has nothing to do with the calendar which must be changed during any month that does not have 31 days..

Wow, I didn't know that, thanks. I guess I always figured that a perpetual calendar would be standard on a Rolex, but I now I know.

Can anyone tell me the main difference between an 'M' series and the current model?

[Tools]

Can anyone tell me the main difference between an 'M' series and the current model?

An M serial number would be a current model..... There have been no announced changes for the GMT II..:cheers:

[ayres]

does anyone have weight data for the gmt2c (overall weight, and weight of case without bracelet)? i would appreciate knowing how it compares to the discontinued gmt2 and the sub date.

i know these weights have been posted in other threads previously, but it is so difficult to find those threads. and last time i checked, there was no posting in the reference library. please correct me if i'm wrong. cheers,

[AKRolexfan]

I may have missed it on the forum, and searched, but...

is there is any difference in buying a Z, M, or a V serial numbered GMT IIc?

From the pictures posted on the For Sale posts, the differences are not apparent. The postings also do not seem to indicate the differences between a an M serial numbered watch vs. a V serial numbered watch, etc...

Just interested in any substantive differences, if there are any.

(Will be in the market for one and am performing my due diligence.)

[jimw76]

hi bro, im new hand ,if i adjust the date with backward and then upfront again, will it have any effect on my GMT II C ? pelase advise.

thanks .

[equinox308]

Dear GMT experts- question, I noticed my GMT 2C's power reserve is only around 24-30 hrs +/- and not 40+ hours like I've read.

Is this a common thing for the watch or some defect (underlying issues) to be concerned with?

MY other issue is the luminova seems to shine brightly as soon as it is exposed to the sun, however, within an hour it is way gone (zero glow)..common issue or my bad luck of the draw in watch received from AD?

Thanks very much

Hi

You can adjust the time and date backwards and forwards without problem, and at any time.

Hi

Are you fully winding the watch i.e. at least 40 full turns of the crown? (don't worry, you cannot over-wind it)

The lume requires fully charging e.g. from a flashlight before it will last for any length of time.

Hi

There is no difference at all between Z, M or V. It is just a case stamp, indicating an approximate date range of manufacture.

Thank you for your response Psmith. I have only been winding it roughly 20 times each time and will try 40 like suggested.

On the lume, I've had it in the sunlight as long as I can before- roughly 3-4 hrs and most it last was no more than 1 hour brightly and another hour very dimly...rather disappointed with this issue.

BTW, mine is M serial # bought in 2007

No problem!

Rolex lume is not that great. To get a longer lasting glow, try using a high-power flashlight to really charge it up. Ambient light - even bright sunlight - does not give much of a charge.

[AKRolexfan]

Please excuse a question from a newbie...

What is the current/ known progression of serial numbers for the GMT IIC?
Is it:
M
V
Then R for Random... or?

Thanks.

[Tools]

All Rolex watches follow the same serial system, however slower sellers may not be maunfactured and released during the same timeframe as those that sell (and therefore deplete their serial number allocation) faster ..

.......... Z, M, V, and then the latest random serial numbering is correct..

[Slopes]

Yyyeeessssss!!!! Just bought my first Rolex last week. GMT Master II 2010.
Loving it.
I may take it off my wrist one day....:thumbsup:

[DCgator]

Excellent choice in the GMT IIc. This model looks very clean and attractive because of its simplicity.

[mikelprz]

I wonder if they will make a new pepsi model ??

IMO the greatest Rolex of all time! GMT!

Is there any info on how many, of each serial #, are made before they move to the next number? (I always thought the serial tied to the "year")

And if known, specifically the GMT II tt 116713?

Thanks in advance!:thumbsup:

Thanks in advance!:thumbsup:

The serial is not tied to a "year", but rather to a set of years that the model was known to be on the market... Almost all serial letter prefixes were used for 2 years and some were used for as many as 4.. Rolex has had two or three prefixes in the market at the same time too... Since there is a letter and 6 numbers, then they likely released close to a million serials with each letter throughout the line

However, Rolex has never released production numbers, so it is unknown how many watches they produce each year, or how many of each model within the line are produced.........:cheers:

The 116710 BKSO means: Black dial, Stainless Steel, Oyster

The 116710 LN means Lunette Noir (Black Insert)

These are marketing and inventory codes for the exact same watch.. The Black ceramic insert GMT II
