Oh ! did Japan market 62mas in 50's have radio active lume? If no, it's definitely change my perspective quite a lot.
Yes, but only a tiny fraction of 62mas examples were radioactive. They came from the Daini factory and were meant for export. It was the 60s not the 50s. Actually, a number of Seiko models from the 60s had this same radioactive lume, and the lume often has a distinctive brown color. There is a thread on WristSushi about these watches.

Thank you very much. This definitely enlighten me. I like 62mas, but avoid the original ones because of the Radium. So, SJE093 is my top target. But now, I think I’m going to hunt for the original one instead.

It's actually quite difficult to find a radium 62mas. I would like to add one to my collection, and I have been looking several years for a good one. The vast majority of 62mas examples are not radioactive at all, not even tritium. Just look for green lume.

There appears to be a radium 62MAS for sale at Blair Watch Project currently...

Thanks for posting. The lume looks as I would expect and presumably the seller has confirmed the Daini origin, although no photos of the inside are shown. That particular example is not what I'm looking for, unfortunately.

The more I hunt for a good example of a 6150-8000, the more I realize how rare some of these are.. especially when compared to a vintage Rolex or even Soeedmaster.

People wore them like tools and didn't try to preserve them.

I see some in decent shape on Chrono24 in the $1800-$2000 range.

Edit: I looked again, and actually most of those have some issues with discoloration around the lume plots.

I’ve been on the hunt! Decent ones (not collector grade) are hard to come by.

There’s a few nice ones from Japan on eBay but the asking prices are way high.

You could just succumb to your obsession and wildly overpay. That's what I did for mine 😬.

There’s a 1968 proof/proof on eBay right now with what I presume is the early radium lume, very interesting. I would snatch it up but some of the radiation readings from these things on the earlier referenced thread were quite alarming:

Just do it!
I've read* the results from radium have a 50:50 chance of either causing death or leading to super powers.

  • Disclaimer: individual results may vary from these two options or greatly favour one over the other.
  • I just look at the pictures.

Someone's wife was reading The Radium Girls and might be a better consultant.

Hi all,
I am new to this forum about the 6105-8000 Seiko.
I was in a local 2nd hand shop about three weeks ago
waiting for my other half. I saw this box of old watches
so had a look through and saw this diver's watch which
was still working. I asked the lady at the counter how much,
and she said £ 2.00 so I purchased the watch. When I got
home I researched the watch and it turned out to be a 6105-8000.
It has green lume's and a seven numbered serial number starting
with 97. I have been wearing it most days and it keeps ok time.
I do not know the service history. I now realise i am very lucky to
have a watch like this with out even knowing about this watch.

Martin.

That is plausibly a Daini model. Or it could be relumed. One would want to see the inside caseback to be certain.

I can't tell if I think that's radium lume or a relume. Does anyone think it looks too clean for old radium? The color of the red dot on the second hand does look good to me - it looks just faded enough.

That said, it is still tempting for the price. It's been hard to find decent examples of these for under $2K.

I saw it and assumed that it was a relume. If the lume were original I wouldn't have expected the handset and bezel pip to look exactly alike, although I suppose it's possible.
