3185 vs 3186

3186 movement...

It's me again,

Can the gurus here explain what is 3186 movement?
What is so special about it?
I heard that they did not produce many this type of movement? Why?
Is it only GMTs have this movement?
Really keen to know more about this...

Thanks in advance!

Some rumours say 'M' series explorer2 has 3186 fitted in too. Don't know whether is it true.

apologies but it's pretty tedious to plough thru all the info in google but isn't GMT and exp II both fitted with the same movement? thot the only difference in the fixed and rotational bezel.

any views?

Yes, the 16710 GMT Master II and 16750 Explorer II are both fitted with the 3185. Howver, the point of contention now is if indeed the upgraded 3186 movement are found in some of the last few batches of 16710 as were reported by some overseas owners, particularly those from the U.S. This does not generally imply that Explorer II would also contain the upgraded 3186movement as this has not been reported but was purely an assumption based on the fact that since it share the same 3185 movement as GMT Master II it would seemed logical to incorporate the 3186 movements in the future productions of Explorer II. Whether the latest Explorer II will be or have already been fitted with the 3186 movements is presently at best just rumours since there are no such reports yet. But whatever the development follows, it should be taken with a pinch of salt until local owners can attest to what were reported. juz my 2cents

I got this from rolex reference page. http://www.rolexreferencepage.com/5.html


SPECIFICATIONS:

Model: GMT Master II
Reference: 16710
Series: Y
Movement: Rolex Caliber 3185
Water Resistance: 330 ft./100 m.
Case: 903L grade Stainless steel
Crystal: Synthetic sapphire
Notes: The original GMT Master was created by Rolex back in the 1950's in conjunction with Pan Am airline as a tool to help their pilots who frequently crossed time zones. The Master II was introduced in the mid-1980's, and eventually replaced the original GMT Master (discontinued in 1999). Rolex purists have great affection for the GMT Master II as a tool watch with a great history and tradition among professional pilots. I acquired my Master II in February of 2004, and have been surprised by how much I enjoy wearing it. More often than not, it's the watch I enjoying switching too when I come home after a long day at the office. This early Y Series example is the last series to have drilled through lug holes (later in the Y series production run, Rolex switch to solid lugs without the hole visible from the outside of the lug).

SPECIFICATIONS:

Model: Explorer II
Reference: 16570
Series: Y
Movement: Rolex Caliber 3185
Water Resistance: 330 ft./100 m.
Case: 903L grade Stainless steel
Crystal: Synthetic sapphire
Notes: The Explorer II is one of Rolex's newer models, having been introduced in 1971 as a supplement to the original Rolex Explorer, and with the current model 16570 having been introduced in 1989. The Explorer II was designed for cave exploration, or any other sort of extended expeditions where the wearer would need a reliable way to determine day from night. The red "GMT" hand used in conjunction with the 24 hr. markings on the bezel serve this purpose. I purchased my Explorer II new from an authorized dealer in February of 2004, and the is early Y Series example is the last series to have drilled through lug holes (later in the Y series production run, Rolex switch to solid lugs without the hole visible from the outside of the lug). The experience of receiving it will always be treasured as this was the first brand new Rolex I ever purchased. The Explorer II is the Rolex watch I most often wear, both dress and casually. The white dial and understated bezel make the watch an excellent choice to wear with a suit (one of the main reasons I purchsed the watch). The ability to track a 2nd time zone also makes the watch ideal to wear while traveling. While the watch is highly sought after in the Pacific Rim, most US dealers I speak to say that the Explorer II is one of the slower sellers in the Rolex line up. Given the versatility and functionality of this watch I'm actually surprised it isn't one Rolex's most popular models.

serious?! does that mean the crb will be in the discontinued gmt-II minus the excorbitant price of a gmt-IIc?!

doubt the crb will be in the 16710 since its discontinued but if the 3186 caliber is indeed found in some of the last few batches (like z or m series), then it may be quite a find. 1 thing to note is that such anomaly has only been reported in the z or m series 16710 with the unusual variant "GMT Master ll " dial. maybe the print of "GMT Master ll " in 16710 was not due to Rolex quality control issues as some had previously thought, but more so to indicate that it contains the 3186 calibers. these are just posts by overseas owner and has not been reported by any local owners. So maybe local owners of 16710 with the variant "GMT Master ll " dial could shed some light on this.

Hi guys,

I once posted here pertaining to speculation over the possibility of the new Rolex calibre 3186 movement in the ceramic 116710 being found in the discontinued 16710. Heres an interesting development to the discovery.. it appears that the 16710 were still being produced right into the M series and an owner with the unusual "GMT ll" dial in this series were found to contain the new upgraded Rolex calibre 3186 movement that was thought to be only found in the new ceramic 116710 .. Though this development has only been reported by an owner in the U.S., I'm sure some of the local owners of the 16710 with the unusual "GMT ll" dial would probably be eager to find out more on this. So for sharing purposes, below is the link to what was posted in that forum

Dammit. Always something with these Roly buggers! Hey, from the sounds of it, the GMT pepsi is still quite easily available 1st hand in the US of A?

Juz to share, this is the latest link on the anomaly of which 3186 movement is found in the 16710.

Interestingly, the manual that comes with the M series Pepsi 16710 specified that its movement is the 3186 caliber (though it could just be the manual meant for the ceramic 116710 that was bundled together). So I guessed this pretty much fuelled the speculation that the 3186 is in the last few batches of the 16710. Wonder if one can still find the last batches of 16710 that does indeed come with the 3186 movements in local markets and how such anomaly (if indeed true) would in a way be in a collector's wishlist.
