Hello everyone!

I recently acquired a Rolex GMT Master 1675. Its a 1.6 million serial so that would likely put it at around 1967. However, I am not by any means well versed in the subtle variations for all the dials and wanted to know which dial variation my watch has (I'm thinking Mark IV or V based on what I have researched) and would like this esteemed community's input. Pictures attached.

Happy Friday!

Service replacement dial….looks like mark V

watchuneedthemost · 25 February 2023, 05:12 AM

How did you come to the conclusion that it is a service replacement dial? Also, are all Mark V dials service replacements?

watchuneedthemost · 25 February 2023, 05:15 AM

Actually I was on the verge of ruling out Mark V since all the Mark V's I looked up online seem to have the right hand line of the "M" in "Master" line with the right most end of the "C" in "Chronometer" right below it......thoughts?

The Dial reads "SIWSS - T < 25" at the bottom

TimeToGo and berdboy, I think I have my answer.....I'm convinced its a Tritium service dial.

Yes a tritium service dial - it's not the knock on value/aesthetic that some, say Swiss Luminova dials, are i.m.h.o.

watchuneedthemost · 25 February 2023, 06:16 AM

True, but does not matter. I really like how the tritium has aged wouldn't have that with a luminova dial

The dial depicted in the first post is a GMT 1675 service dial.

For additional GMT 1675 dial clarification, if you search the GMT 1675 dials at gmtforum.com you'll find photos of the Mark IV and Mark V dials:
