Hopefully I'll be posting up pics tomorrow in a new thread for your feedback. Be on the look-out for me please!

1966 should be a W-1 dial. 1970 W-1, possibly W-2 based on serial number.

If the serial number is under 14XXXXX on the 1966, it might be a gilt (gold) lettered dial.

Post up some pics tomorrow in a new thread and also list the serial numbers. Good luck.

Thanks very much, will do. I certainly plan to compare them to the dials you posted to check for any inconsistencies. But I will also take a lot of pics (and I'm bringing along the ollo clip macro lens for clear pics).

I look forward to everyone's feedback!

Great Post!

John, great post! Thanks for sharing your expertise with us. Very enjoyable to read and become educated.

Is this dial bellow considered a Service Dial then?

Would it be correct and compatible with a late 70s production? What serial range should be then?

Thanks in advance!

It is not a service dial but a late 1970's dial.

Thanks John.

Then this one bellow is what is called Gilt dial since it has a gold lettering, correct?

Looks very "gold" to me. Usually in photos, it is hard to distinguish the gilt dials from the white-lettered dials. Hands have been replaced. I'd have someone local check the dial to make sure it's genuine.

Uh, ok! Thanks for the advice and heads up. My head and eyes keep spinning here trying to compare your dials pics with some other finds online that I'm trying to research to me. I wanna get the right 1675 to my collection, so…

6542: RSC Refinish Example

Enjoyed this post!

Bob Ridley recently received an interesting 6542, and asked me to post his reference pictures.

This is a RSC-authorized refinish from 1971. The watch serial numbers match the paperwork, so it's a verified example of what an authorized refinish looked like in 1971.

I tried to figure out what you and others were talking about the difference in the gilt dial and the white dial. I could not see it in the pictures. Then I got a chance to see them side-by-side at a vintage watch dealer. What a difference. Now, I can even see it in the pictures.

In reviewing this thread for someone today, I noticed that a few white-lettered GMT 1675 dials were missing and wanted to update these dials. My original intent was to have these dials in chronological order but it didn't work out that way and I apologize. One of these days I will try and get everything in chronological order. With the inclusion of the three dials below, all of the white-lettered dials are pictured within this thread, which according to my last count is 9 dials. The dials are, MARK 0, MARK 1, MARK 2, MARK 2.5, MARK 3, MARK 4 MARK 5 MARK 5.A and MARK 6. Below are examples of the MARK 0, MARK 5.A and MARK 6. (If you have not read the complete thread, the white-lettered dials are identified with a W prefix, such as W-1, W-2 etc which is how I identified the white-lettered dials so they wouldn't be confused with the gilt dials which are identified with a G prefix.)


The MARK 0 dial is the first variation of the white-lettered dials and appears in the late 1.4 million serial number range up to possibly the 1.6 million range serial numbers. The MARK 0 dial appears very similar to the last variation of the gilt dial. The coronet also appears similar to the MARK 2 white-lettered dial. From my personal observations, and others I have talked with, the MARK 0 watches had the small 24-hour hand as "original equipment." The GMTs with this dial rarely show up for sale and are rather elusive.

The MARK 5.A is a variation of the MARK 5 dial, with font spacing somewhat different along with a slightly different coronet than the MARK 5 dial. The time frame for this dial seems to be from around 1976 until the late 1970s - the same era as the MARK 5 dial.

The MARK 6 dial has a very long, slender coronet and from my experience, appears to be the last variation of the GMT 1675 dials from the late 1970s. This dial could have been used as a service dial at some point in time.

While some here might not agree with my assumptions, my observations and conclusions are based are many years of ownership and time studying the various Rolex GMT 1675 variations. I am by no means an expert, but do enjoy the GMT models.

John, thanks so much. This is such a great resource and should be a sticky, imo. Would you consider doing something similar for GMT bezels?

Thanks for all the info, John. I still find all the GMT dial variations to be utterly confusing.

Please could the experts advise if a circa 1962 87X,XXX serial case, with pointed crown guards would have a Non-Chapter Ring dial, the one I am looking at appears to have the "SWISS" Underline dial. I dont think I can post pictures as I am new to the forum.
Thanks in advance.

I have seen the "swiss" only non chapter in watches from 870xxx through early 1.1 mil.
Having not owned one from new it is not a perfect science. I always thought that the 1.0 mil was the area of manufacture for swiss non chapter but with GMT cases at the end of the production cycle of gilts we tend to see mixed. Case backs sometimes tell more of a story than the mid case numbers. Just my personal observations. m

Icon14 Excellent add ons JP...

and modest of you to say you are not an expert

I was revisiting this thread after nearly two years away and saw that you have updated the thread with the MK 0 which I was thinking of mentioning it here.

Keep adding on and you can be sure I will keep coming back here to look for updates & add-ons

Amazing information, thank you JP!
If I may ask, here's my 3 Tritium 1675's and I will admit I'm a bit lost to which dials they have. To me the first two have the same coronet although the SWISS-T is closer to the hour marker on the first than the second.
Hoping you may help please?
Thanks.

First two are Mk-1, the third a Mk-4.

The first one may have been relumed but would need to see better pictures. As you say the "Swiss T" is closer to the hour marker. Look at the plots 4 & 5 as well, they touch the minute marker.

Nice collection - Love them GMTs!

Thank you and thanks to the others that have posted here lately. One of these days I hope to redo this thread and organize it better.

The link below identifies the 1675 variations better than the one I posted here.
