Just when you think you've seen it all, along comes the Nuclear Watch. Gadgets and Gear's Nuclear Watch is an always-glowing wristwatch that's packed with 100 quadrillion radioactive hydrogen atoms. The atoms in the watch comply with the Nuclear Regulatory Commission's (NRC) strict guidelines on radioactive safety, so there's no need to worry about a nuclear meltdown happening on your wrist.
The decaying atoms of the Nuclear Watch can provide light for its hands and dashes for 25 years. In addition to providing a quarter century of light, the watch is also waterproof for up to 300 feet. Not many watches can claim to be either of these things, making it all the more impressive. The Nuclear Watch is currently on sale for $175, or $7 per every year of light.
