Tritium Dial or T < 25

[Zi Pie']

Hi folks,

When did Rolex stop making tritium dial with the mark T < 25 on it? For what I read online it seems in the late 90's.
Can anyone confirm ?

The reason of my question is that I found for sale 16713 GMT II Serti with a tritium dial but the watch production according to the seller is 2004 (it has no holes case), so I am little skeptical on the authenticity of the dial.

Thanks much.

Up till 1960 Rolex used the word SWISS then dials were Radioactive Radium from around early 1960 on Rolex used T.Swiss.T less than 277 MBq (7.5mCi) and Swiss <T25 less than925 MBq (25mCi)on there dial depending on how much radioactivity they had from 1960 till mid/late 1998.Swiss only dials were then used with Luminova from 1998 to 2000, then after 2000 back to Swiss Made with Superluminover now lume is chromolight more on the blue colour spectrum

Thanks that helps a lot. So technically is not possible to see a Swiss <T25 on a watch made in 2004. Pic of the watch in question.

There is a YouTube video from Hodinkee that runs through all the reference points of the GMT. I believe it talks to the point you are concerned about, the guys in the video seemed very knowledgeable.

I will see if I can get the link to post. https://youtu.be/P6HHBnxyY7E?si=gGH_SaFqbemEqVhx

What is the case serial of watch in question,and back then TT serti dial GMT watches were not the fastest sellers,and no internet chart can give a exact date when any watch was made only a approx date between X-Y years.
