Production year and lume material on Orient Star EROM-CO CS

Hello all of y'all!

As some might realise from my post history, I'm a bit fanatic when it comes to (not) having radioactive materials in my watches. I know Tritium is hardly dangerous when inside watches, not to mention the very low half life. But I just don't want to think about the what if's...

So I'm looking for information about the production year and lume material on the Orient Star EROM-CO CS. Information about this watch is hard to come by. As far as I know the production years is around 2000, which might mean it does contain Tritium, or that it doesn't.

Please let me know if you know about either one 😄

I believe most major manufacturers stopped utilizing radioactive paints officially in 1998.

But for that specific model, will have to await the gurus.

I've read from 1997-1999, perhaps with production stopping in 1997 and units sold out in 1999. 2000 should put me in the clear then, but with no information readily available, we're in the hands of the gurus as you say 😄

If you can have the seller take a video of the lume you should be able to tell by how quickly it fades. I have an older Carrera from the mid 90s with tritium. If I put my flashlight on it, it glows, but completely fades out after 30-45 seconds. Even aged luminescence will last longer than that.

Thanks!

I've also found out, by searching chrono24 for Orient Explorer, that it seems to be produced from 1990-1996 or so. That doesn't really better the chances for a non-radioactive photoluminence 😢

If tritium was trouble, you’d know. So I don’t think you should worry.

How do you mean?

Like when you read about radium watch paint, you can very easily find information about it being bad. If tritium lume was bad, you would at least find this information on watchmaking related forums.

I don't see your point. Tritium is radioactive and I don't want to have radioactive materials on my arm, contained or not.

My point is that you’re being a bit paranoid, to be frank about it. You get more radiation from dental X-rays, but they don’t harm you. Like, there just isn’t a “what if” about it. There are very strict legal requirements about radiation and the watch industry is very sensitive to it. It’d be like worrying a flat tire is going to burst.

I don’t think these have tritium paint. If even then you don’t trust what we say, move on to a different, more recently-produced watch

I'm quite aware I'm not going to get radiation sickness or anything from wearing the watch, but the thought of inhaling Tritium dust by accident when regulating makes me not want to own Tritium watches - hence the wording in my post 🙂

I don't see the "we" you're referring to - I think it's only you making an actual guess on whether it's Tritium or not. Production years in the 90's does make it somewhat likely to be Tritium or Prometheum, but I'll gladly listen to arguments otherwise 😄
