The Rolex GMT-Master II (ceramic model)
2 Attachment(s)
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:

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 |
Mine says PJ1, and no number underneath either.
|
Mine says E010
|
Mine says E09
|
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.
|
Excellent write up as always.
|
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! |
those letters on the bracelet indicate when the bracelet was made...there is a chart on line if you google that info

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

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 Attachment 67231 This shot shows the clasp flipped over to expose the slots for compressing the spring-bar Attachment 67232 |
Cheers...managed to sort it out with a sharp knife!!

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

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.

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...

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