There is also the service dial with super luminova material marked SWISS at the bottom. Photos of the service dial with tritium and super luminova are in my first post.

Thanks for the clarification and hard work on GMt dials, Springer

Does it also mean that Mk1 dials have puffy plots which would glow briefly like 1967 meters first 5513s ?

Not all Mk 1 dials as there are some white puffy plot dials.

I would agree with this assessment'

Not all Mark I dials are "puffy" from the white-lettered font era - to include the 1967 dials - although some definitely are puffy. Additionally, based on my experience, they will glow for a short time when exposed to light.

Great post thanks!

Always looking to learn something new. Great reference material!

Why isn't this stickied in the reference section??!! Beautiful!

Great post John! I have been searching for informative posts on the dial variance of the GMTs but found most to be lacking. This is one great post that deserves to be mentioned and referenced to where GMTs 1675 are concerned. :)

Nice information John. I find the most variable styles in the GMT sport watches and dating the proper dials to case years almost impossible sometimes. Always good to have a refresher course of information. :-) M

Thanks Mike. I find some of the gilt dials hard to date since there were so many variations in that seven year run. There was definitely some overlap with the dials from year to year.


Doesn't look like I'll be making it down to Miami but you guys have fun! I haven't spent much time there since I moved from Broward County many years ago and was looking forward to a return visit to see some old friends.

[watchcrank]

Too bad you won't make Miami John. Should be fun! We will miss seeing you.
best regards, M

Since we are on the topic, is mine a Mk5?

It is one of the Mark V dials. All variations of the Mark V dials have photos depicting them within this thread.

[checkwristdon]

Is it legit to have 1675 in 6.4 million series?

Excellent post John! I agree should be stuck as a sticky!

Thanks Dave and everyone here on TRF. Hopefully I didn't cause additional anxiety for anyone here.

Remember to add the OCC dial from 1959, and early 1960.

This is the rarest version of the 1675 dials, produced for a very short time when the model was first introduced. As 6542 dials are not interchangable with 1675 dials, this dial is unique to this early 1675 model.

Thanks Jeff. The coronet on the dial that you posted mirrors the coronet on the G-3 photo of mine. The difference that I have noticed in these two dials would be in verbiage on the dial and the underscored line below Officially Certified. The one in your photo reads "Officially Certified Chronometer," while in my G-3 photo it reads "Superlative Chronometer Officially Certified." (The G-3 photo is from a 1675 circa 1961.)

The subtle differences in some of these dials make a difference to many collectors. With seven variations of the gilt dials depicted in this thread, and a GMT 1675 production run of approximately seven years, most of the dials are fairly rare - except for the last two which seem to be the most prevalent of all.

very nice John, thanks for your nice work

Here are two more photos of another variation of an early gilt dial, circa 1960, serial number range 63XXXX.

Hi John, Excellent thread!!!! ....but I have also seen this type of coronet on watches with a later S/N...

This one with 87X,XXX...



And this one with with 82X,XXX S/N....




Thoughts?

It could be possible. Most consider this dial an early 1675 dial. Nothing is "in stone" here but intended as a guide. That is why I didn't try to place too much emphasis on cut-off dates for the various dials.

great thread. I notice 1 out of the 2 service dials says "swiss - t<25", i thought all service dials said "swiss" at the bottom? also, how could you tell if a dial that does say "swiss-t<25" is a service dial?

thanks

There are actually three service dials posted. My original two and the third one in TTG's post. The tritium dial and luminova look the same, marked Swiss-T<25. The super luminova is marked SWISS.

You can distinguish the service dials by the coronet.

Tritium dials will usually have a patina on them when compared to the luminova dials which are usually white - many of the luminova dials have a "colored-glow" to help distinguish them. Another way to distinguish the differences between the two is the luminova dial lights up fairly bright when compared to the tritium dial.

In response to your questions regarding the dial markings, no, not all service dials are marked SWISS, which holds true for the Submariners and other models as well.

oh i see....always thought it had to say swiss. thanks so much for the quick reply.

They replacement dials have been marked SWISS for many years. The tritium replacement dials have been out of production for a few decades now - since luminova replaced it.

Thank you for posting. Very informative.

[AirKing527]

yeah i could see that byt the fact that the service dial that you posted, the plots have yellowed a bit over time.

Hi Springer,

Great post and discussions here on the dial of 1675.

One thing really puzzled me. Orchi, a forumer here, also did a thread on the dial variance of the 1675 (thread: ROLEX Ref. 1675 GMT Master Dial Variants) (http://www.rolexforums.com/showthread.php?t=74976). What he had discussed there seems to contradict what you presented on this thread.

For example, both the threads mentioned different MK I of the 1675, although they were known by different names. The ones you mentioned were gilt and white dials whereas his were matt dials. Which came first though? or both came concurrently? or the matt dials were also known as white dials?

Would love to hear your advice and thanks in advance :)

All the answers to your questions are in the beginning of this thread. Gilts came first and were replaced by matte dials with white lettering.
