HELP: Omega Seamaster 30 lume information

Hi! I am interested in a Seamaster 30. I am looking at one from 1963, but I am wondering about the type of lume it has. I believe there are no Ts on the dial, thus not sure if this would be tritium or radium? Any comment or something to look out for?
Thanks

Just a short addition to my previous post.... I would see this as a most days watch, but I am a bit concerned about the radiation potential of some older watches. I understood that Omega introduced tritium in its lume in 1963, so the model and specimen described above would sit somewhere on the edge of that period. I know that some collectors are not so worried about it, but you never know.... I would welcome input from the knowledgeable members of this forum 😀

I'm not sure about the model you're thinking about, pics might help someone here identify the lume.

Tritium lume is nothing to worry about in most circumstances. It's my understanding that the radiation from tritium cannot penetrate skin. If you open the watch for service, or happen to break open the crystal, you must take care to not ingest or inhale any tritium-containing dust/particles.

Radium is more of a concern, as Radon gas is created as it degrades. If you own a watch with Radium lume, you shouldn't keep it in a bedroom. Best practice is to store it in a hermetically sealed container, and only open the container outdoors before you put on the watch.

Thank you for your answer @sleepyastronaut! Indeed, Tritium I would not be so worried about as half life is relatively short. My concern is that it would be a radium lume dial. I have not seen the watch, yet. It is local and have seen one add on a local trading site. I was planning to explore, but before I went I wanted to see whether it was worth my while... I would want to refrain from ending up with a radium dial, maybe it is just me, but I am not that keen on the idea. From what I have seen, Seamaster 600s are marked with T on the dial, whilst I have not seen Seamaster 30s with that and thus am a bit confused on what to expect. I tried searching large and wide on the internet, but I have to say that information is few and far between...

If there is no T on the dial and it is indeed a lumed dial (there were non-lume dials that didn’t get the T’s) then most likely it is radium. I don’t try to convince one person or another about the legitimacy of their fears- if radiation is a concern and there is indeed lume on the hands and dial, pass on this one.

Not just you, I love the look of the 1940's Omega dials, but not enough to bring one with Radium into my house.

You can either get a 1940 Omega without luminous, or may be you should invest in a Geiger counter.

The mortality rate of Vintage military watch collectors is not higher than the average.....and here we talk about radium dials with 12 fat radium numerals and large hands . With lots of radium. 2 things: A. radiation will be next to zero at your wrist. B. Unless you wear your radium watch around your throat facing up and pointed at your brain 24/7/360 , you should be fine. And that is Radium. If you talk about the small dots on omega dials and the small slots in the hands for luminous material, you will be safe. The background radiation is everywhere. Borrow a good Geiger and check it out where you live.

That's fine, still don't want a watch with Radium, and not asking to be convinced otherwise 😀

Thank you all for the active discussion. I contacted the seller. The watch was serviced not so long ago, so he will contact his horologist and enquire about it. I checked the pictures and yes, there are the usual lume dots on the markers and on the hands. Very nice watch, IMO otherwise. Just this thought that would sit in the back of my head until I would then decide to get rid of it. Perhaps I know myself too well :/

From what I could see, 600 models are marked with T as they came a bit later. This could be an alternative, unless as for suggestion of @sleepyastronaut I manage to find one without lumes... I am not in a hurry and time will come. I am somehow partial to the 30 model though, that's why I didn't yet go for the 600 or other Seamaster models. But there is no rational reason for this.

I will keep you posted, if I find out more...

Hi all, another weird question for you, in relation to Seamaster 30 lume. I have come across a Seamaster 30 that looked somewhat appealing. With my radioactive quirkiness, I had been keeping away for a while... What has been striking me is that it appears that this one has a T on the dial, which spells out either a dodgy dial or the fact that perhaps some T models do exist? From the serial number it appears to be perhaps a 63 model, if my interpretation of the last 2 digits of the number is correct? Here go some pics for you to browse. Thanks for sharing your views, they are always an informative and enlightening read!

Looks fine. Prob made in early 1964 hence by then tritium dials had the T marks.

Thank you @padders 😀 As I said, I was under the impression that T models were a bit less standard, or at least I had not come across one yet. I like the SM30 a lot, but was always a bit reluctant due to the radium lume or potential radium lume. Thanks also for pinpointing the historical timepoint 😀

Personally, as someone who has studied Nuclear Physics at Uni level I find the knee jerk fears over radium overblown and have several such equipped watches but I respect the choices others make when they avoid them: all the more for meeeeeee!

thanks! 😀 I will keep you posted, if I find some nice glow in the dark ones 😁 jokes aside, you are probably right. It is just that the tought would probably stick with me and lessen the experience... But I often see some really interesting objects out there, especially of the older variety and then i sometimes question my questioning 😁

The Seamaster 30 in the photo sure looks like tritium based on the colour. I have a 1963 Seamaster and it is tritium. Radium lume in good condition is usually beige and tritium generally has a greenish hue. They can both go an ugly dark green when oxidized.



I have a very early 1960's Solar that has a radium dial and tritium hands. The watch is apparently all original, and pristine condition, so they probably ran out of radium hands but still had some dials left over. The hour markers glow all night long but the hands only glow for 2 minutes immediately after exposed to light.

Totally agree with you, respect your feelings and fears, there's plenty of no lume vintage omegas out there 😀
