Rolex GMT II

The GMT Master II has some features that the GMT may or may not have, to the best of my knowledge. Bot watches have two hour hands- the 12-hour one and the 24-hour one. The 12-hour one on the GMT II is individually settable, forward or back. In fact, setting the 12-hour hand is used to re-set the calendar. This feature comes in handy when travelling. Leave the 24-hour hand on GMT, and re-set the 12-hour hand as you change time zones. This feature is activated without re-setting the minutes and seconds. Does the GMT have this feature? I have a GMT II, but I don't have a GMT. Had one years ago 'til someone offered me stupid money for it.

They have both, they sometimes mislabel individual watches, not entire categories.

As far as GMT functions:

Fist Gen GMT have the GMT hand (24 hour hand) fixed to the hour hand, with no way of independently setting it. Also no hacking mechanism. The only way to set up the date is to rotate the hours full 24 hour increments which is a pain in the ass. The GMT function is achieved only by setting the bezel in the desired place to mark the GMT time. this is true for the

Around 70/71 they came up with the hacking mechanism with eh 1575 cal

In the eighties the introduced the quickset feature (16750) also introduced the much more advance 3075 cal that had 28800 a/H before that the cals beat at 18000 and 19600 i believe. also they moved into 100m (330ft pressure/water resistance from the prior 50m

In the mid eighties they introduced the sapphire Crystal, this is the birth of the Master II (16760 "fat lady") , before that it's Master. So when you see a circa 1960's and 1970's gmat master II at bob's watches it is a mislabeled master. Also with the 16760 in mid eighties they started the applied white gold markers, some people see 16760 with applied markers as transitional..they are, sort of. also they had the independent hour function

late eighties though nineties they transitioned into Luminova from Tritium

sort of overlapping into the new millennium you have the 6710 returning to a slimmer design and with the independent hour hand the 16700 didn't have the independedn hour hand for some weird reasin since the 16760 had it). this one changed to no holes around the F series on 2004. They had the 3185 caliber up to late 2007 when you can find the 2 stick version as they transitioned into the 3186 cal. by the M serial the 3186 was mostly transitioned9Circa 2008/9 So when you find a 2004 F serial with cal 3186 cal at Bob's watches it's an error

Lastly the modern 116710 has the ceramic bezel and shares the thicker and less elegant sub case. loosing IMO the elegance and grace the GMT had through it's history. Not that I don't like big divers or watches, but I liked the proportions of the GMT pre ceramic.

There are transitional between all these series.

Are you saying both the GMT Master II and the GMT Master have individually settable hour hands? I'm at your mercy there, because I don't know for certain. If they both have individually settable hour hands, then what is the difference between a GMT and a GMT Master II? I think it is vital that the OP know what is what, in order that he decides on a watch that best suits him.

It is all specified on the post I made. Mid eighties Master II came into place on the 16760 . Introducing the independent hour hand. However the reference 1670 which overlaps does not, while the 16710 does. (one of the only differences between these two references). After that all the Master II to date have the independent hour hand and the biggest notable jump for buyers would be getting a 3186 caliber with the antimagnetic and 10X shock improvements. That would be going into a M series to be sure (ish) circa 2009 although you can find some as early as 2007 normally identifiable by the two stick master logo (II) instead of the roman numeral

Whatever you do don;t be at my Mercy. I am a bad person.

I think I may get there one of these days. I don't write them off completely. At this point I really enjoy the aluminum bezels and thinner profile. I have a 5512 Sub and am looking into a larger modern one but I also have an Omega PO LMLE to cover modern ceramic Divers so I have to prioritize. I would love a 60's Milgauss but they are very expensive and a 60's explorer (probably my next purchase.

This is, to me, the fundamental problem I have with the modern ceramic bezels and superluminova - I want my watches to age and improve with time (pun intended). Every time I look at my BLNR I think that this is exactly what it will look like in 50 years, a 100 years, unless I shatter the bezel and get an aluminium one as a replacement and somehow source some tritium to paint over the plots at the same time...or sell it and buy a 16700 or earlier. 😀

Yes. Go to the 5th floor, that's where the lab is. Basic repairs, adjustments etc they do in house often on same day. Otherwise they will send it out.

Contrary to popular believe they do note exceptions I.e you can service a vintage watch and ask for dial, or glass or polishing to not be done.
