GMT-MASTER ll "misprint" and new 3186 movement

[Roger]

Just to throw a spanner in the works, I have just recently purchased a 16710 Coke GMT Master from an AD with a serial D6***** brand new as opposed to pre owned and the dial most definately has the parallel stick numbers and not the roman numerals.

This would mean that if the rumour is correct, then the 3186 movement was installed earlier than the "Z" series.
Accurracy is +2 sec per day which is identical to my dd but better than the Explorer 1 which is +4 secs.

All 3 watches are totally consistent with the same level of gain each day no matter what the circumstances.

3186 in a D series GMT11? now that would be nice.

This sounds highly unlikely - but who cares? You have a beautiful watch

I have also seen "D" serial GMT II's with the "I I" font.

BTW, if you want to make the stick font and use it in your post you can click on "arial narrow" in the font options.

crank open the caseback!

don't bother, enjoy the watch

One of my other GMT's was a D serial with stick font, and it did not pass the wiggle test.

[Scarface]

It seems then, as we all agree, that the only way is to the case

[errolhiggins]

Interested to know, Thanks

This is crazy. A little face change has me thinking of ways to justify this purchase!!!!!

[mcl1esq]

Don't think this is going to help anyone, but I have a z serial GMT ll misprint dial (pepsi) that fails the wiggle test indicating a 3185 movement. I also have a z serial Explorer II (white) with the rolexrolexrolex rehaut that passes the wiggle test indicating a 3186 movement. The setting of the time, including the 24 hour hand, has a completely different feel between the two wathces. I have not opened the case on either watch nor do I intend to. This would indicate that not all of the GMT ll misprint dials have a 3186 movement. Whether the GMT has a 3185 or 3186, it is still one of the best watches I own, whether a Rolex or other.

No doubt

[Howie]

this is like wondering if you have the golden ticket in a Wonka bar... The sad part is, I just had RCS regulate my watch as it was running 10 seconds fast. This was just days before I found out about this movement issue so I didn't ask them. Oh well, I guess I can wait another 5 years... I've got a Z with the non-roman numeral IIs, so maybe I got a golden ticket?

[buz-lh]

I have a late Z with no wiggle but I think the only way to truly know is take a look and I'm not willing to have that done as I am very happy with my 16710 and it really doesn't matter to me which movement is in it as long as Rolex did it.

[marshallr47]

Good Info To Know. Thanks.

[AL7273]

does anyone know for certain which serial number ranges have the new movements?

[Z-Sub]

My Z74xxxx-serial Pepsi has the New booklet but a 3185 calibre movement.
I'm pretty sure that Z-97xxxx or later numbers have 3186.
So it seems that Rolex ran out of the booklets b4 it ran out of the 3185!!

All M's and all late Z's (don't have the list onhand, but there's one on timezone).

Wiggle test (if done properly) is 100% conclusive.

[AL7273]

Ok, I think I can post here.

[AL7273]

I was trying to say that I am new to the forum and my posting limits are very strange.

Anyway, I am on the hunt for an M-series GMT ii.

Originally I was thinking of just getting a vintage GMT but the M is the way for me.

I wonder how many they made?

[Marrk]

Except that you can get all the "old" booklets you want from RSC N.Y.

Wiggle, schmiggle. Either way the GMT II is a great freakin' watch, period!

[SPACE-DWELLER]

GMT dials sometimes sport different fonts. This "anomaly" is in fact fairly normal....

See these comparison pics:


(Pic originally posted by "GMTcrazy").

Then note this related pic:


(Pic by (Jo)hannes "Baptiste" Kern; oysterword.de).

The latter pic derives from a time long BEFORE the current "Cal. 3186 controversy" started.

Imho, the dial variations must be seen in the light of Rolex having bought the dial supplier Beyeler in 2001 as yet another step in the direction of become 100 % self-supplying. As Al once stated, quoting from a TimeZone article:

""Of all the independent manufacturers, Rolex has gone the furthest towards to fulfilling the old American model of self-contained industrial watchmaking. Over the past several years Rolex started the pattern of acquire-and-consolidate which other independent manufactures have only begun to follow over the past year or two. In a very logical step-by-step process, Rolex purchased most of its primary suppliers, including bracelet manufacturer Gay Frres, dial manufacturer Beyeler & Cie, and crown manufacturer Boninchi SA."

Therefore, the "II" versus ll font does not necessarily indicate the usage of Cals. 3185 vs. 3186. The only and ultimate test is to have the caseback removed and inspect the Cal. # engraved on the bridge plus inspecting if the hairspring is blued or not.

Thank you, This was such a big help!!

When I bought this watch the AD told me it was an older Rolex case with the new 3186 movement. So it turns out my GMT has a Stick ll rather than the roman II. So it does seem to be true that there was a limited amount of GMT's that went out with the new movement's before they released the ceramic black bezel GMT II's with the 3186.

Helps out a lot

I seam to learn something new every day on TRF.

Bellow are some Macro pics of my timepiece along with my manual. I'm thinkin I have the new one, because there's mention of the new ceramic bezel.

It's plausible but I would give more credence if it were posted by other trusted TRF experts.

P.S. I did get the new GMT2c booklet for my M series pepsi.

Well I'm looking inside "R1 and R3" for the uninitiated these are rolex's reference books for parts, the rotors are two diffrent numbers, also there is only one part number for the new GMT IIc's rotor. I though the 3186 was a somewhat different in thickness from the 3185, which would necessitate a diffrent part # for the winding weight if the 3186 was used in the old case. Wouldn't be the first time rolex did something like this though supposedly they were puttiong parachrome Hairsprings in the daytonas as early as 2000. I don't think the fonts designate which watch has it though, I think a certain serial range will determine it.

Pics... I gotta see this. If this is the case I will be hitting the FS forums.
