Wasn't there a GMT service dial with luminova that was marked as tritium?
I seem to recall reading about that.. |

Mid 60’s lume glow. I’d be more worried if it didn’t.
Marking at 6 oc mostly shows the standard at that time. So yes, some lumi dials can have tritium markings. Same as non-lume dials also could have a tritium marking.

Got a 5513 from 1967 that still glows a bit, a 1675 from 1971 that is stone dead and a 1680 from the same year that if you wake up in the middle of the night in a pitch black room you can still make out the plots...

There are numerous Rolex / Omega / Tudor models that all glow and fade fast - not usable off course. Seeing how some of these dials age in a similar fashion (the Grunge dials for example) across brands, I suspect they had the same dial manufactures or at least contracted same Lume formulations. None of that was in house then (Rolex did not have a reactor to extract Tritium as a byproduct of a nuclear reaction for example). So while the Tritium has faded away to < measurable levels in most cases, the compounds they reacted with sometimes STILL react to UV/Sunlight.

Most 1960s don't normally glow as they did when new, some might glow very little or others might glow with a little help.
Below is a 1967 GMT "greenie" as I call them, when the tritium glowed green with a UV or "blue" light.

Dials before 1963 also normally react to UV but depending on type they do not always glow strong. Most react to UV and when radium they don’t need to be charged in order to have a basically constant glow. Much more faint of course but radium kind of never dies if you are in a pitch black room.

Gentlemen, sorry to revive an old thread, thanks for your understanding.
(well, not that old in the end, there was some activity in July, makes me feel better :) ) What are your thoughts about an early 70's (MkII) 1675 that has zero glowing whatsoever under UV light? I mean, not just "not glowing after excitation", but that doesn't show any reaction whatsover WHILE it's being exposed to UV's? Not even the tiniest of "sparklets" as we often see... The seller tells me it's normal for those 70's dials that use post-zync-sulphate compounds, as opposed to the early trit' dials that still often show the sparklets. Not saying it isn't just the case, just trying to learn. Thank you for bearing with all my questions - as you've probably understood for a few months now, I'm hunting carefully, as it seems to be a anything-but-safe world out there... Your kind guidance is much appreciated. Best, Paul |

thanks... so no sparklets. Man, the information sources on the intrawebz are a tough one to crack, eh...
Thank you! Paul |

Not a GMT but my 1978 9411 still glows VERY faintly in the deep dark. It is barely perceptible but it does.

My MMF 5513 from '67 and small arrow matte 1675 from '67 both still glowed faintly. Brightly when excited by a LED flashlight.
