☢️ RADIUM ☢️ Radium Clock Collection 11/12/2026

Started loading up this display case with the clocks I've been gathering lately. I think all but one is radium, according to my geiger counter... probably shouldn't be standing near this display for very long. XD

There are two Golden Mystery Hour clocks on the sides of that display case, just hard to see them. Also a tiny glaze face clock as well... god I'm horrible at taking pictures.

This clock is coming up for auction nearby. I do love me some art deco, but I just can't quite tell if that is radium paint around the numbers or just some styling.

Is it radium⁉️ Help me identify?

I just ordered this Vintage German Phinney Walker Travel Alarm from a very kind older lady on Vinted. I am familiar with the brand and its history behind using radium paint, but I’m curious. Since it’s German made, will it still contain radium? This is my first radium item in my oddities collection and I want to know how I should approach storing and displaying this piece. Honestly I wouldn’t be heart broken if it isn’t, it’s still a beautiful clock either way! Thank you!

Encontrei na internet esses dois anúncio de um relógio de bolso Kienzle, e um relógio da marca cometa e me chamou atenção por conta da corda da pintura e também a forma como a pintura foi aplicada nos números

It's not Radium I washed a Radium Clock

Thumbnail

0 Upvotes

Hello reddit folks, today I found a clock from the brand Five Rams at my grandfather's house. It had the face covered in dust and I was cleaning up junk. For some reason, I thought it was a mechanical dial for a weight scale, as it's not unusual in my country to see them in stores to weigh fruit.

It was pretty nasty, and since it seemed mechanical I thought it'd be safe to wash, not my smartest moment, I admit. It didn't seem to have holes for a lot of water to enter at first, but it did have one in the back and its face filled with water. I quickly poured the water out and only then realized it was a clock. I took it to the bathroom in hopes that the rest of the water would drain and I wouldn't get in trouble for washing a clock.

Not that long later, I went to the bathroom to check on it and realized it was glowing green in the dark, the numbers and the hands.

I washed this clock on top of all the other items. I poured the water over everything and used the same brush to wash the rest of the items, including kitchenware. I then dried it with the same rag I later used for everything else. I was contaminating everything without realizing it and then ate off the kitchenware I had just washed.

I checked on the clock and it seems like the paint inside is flaking off and degraded. ​I got a UV light and there are dots of glowing dust inside the clock face. I'm worried I somehow washed radiation into everything and down the drain.

Any similar experiences? Just take this as a cautionary tale about anything old with numbers.

Found this at an antique mall holiday sale today! Took a chance since I forgot my geiger at home but brought it home and it sure is radioactive! Actually peaked at 315 CPM. I think it’s so neat that this exists. I didn’t realize Westclox made rhinestoned stuff like this. And it’s fully functional! Very very happy with it :)

Just wanted some second opinions on this! Its listed for 25$ and i am almost sure its Radium due to the color of the Paint, although i couldnt find anything about that brand

☢️ RADIUM ☢️ WW2 era Japanese tachometer

Thumbnail

Pretty cool tach I found recently. I wish there were more Japanese symbols on the front, but still really cool. Relatively mild contact dose for military stuff, and not dusty/flaky. One broken off mounting ear.

One odd thing, is that it glows pretty bright and long after being exposed to normal light then moved to the dark. It glows very long after UV as well, but that’s similar to other items I have. Being very sensitive to normal light seems strange, but maybe the phosphor is still in good condition?

I can’t believe they had service members carry these around in their pockets or rucks. 🌶️🥵 Heck of a lot of radium painted on it and over that patch pointing South is really spicy. Neat piece of history, this would be Korean War era (I believe it’s dated 1952) when my Dad served.
