Rolex GMT from 1968 tritium dial / zinc sulfide hands

[Alexander88]

Hello everyone,

I have a question about a dial-hand combination.
A 1675 from 1968 has a Long E - MK1 dial. As expected with "dead" tritium. However, the hands of the watch are coated with the zinc sulfide mixture, which means that they still react typically and briefly under UV light.

Have you ever seen this before? For me, this combination does not seem impossible in a watch from 1968.

I look forward to your opinions.

Kind regards

Alex

In response to your your question regarding your lume, the possibility exists that the lume is original - which is the zinc sulfide variety that normally glows green under the UV light test. 1968 seems to have been a transition year for this type of lume.

Also, be aware that the hands could have been changed to hands that contain zinc sulfide lume or, the hands were relumed with a type of lume available on the internet which can be purchased in several color variations to include green.

Thank you very much for your answer.
The lume characteristics clearly speak in favor of zinc sulfide. In most cases, you can't rule out the possibility that something has been tinkered with in the last 50 years, but all in all the watch looks very coherent.
I assume that it was actually delivered like this in 1968.

Kind regards
