Plutonium Watch

 Nuclear power!
  (+4)
(+4) 		 

No-one has ever looked at a digital watch and exclaimed "I wish the battery lasted much longer than just a few years."

Even if battery life is a concern, a simple solar panel is enough to give digital watches a practically infinite lifetime.

But you have to admit that nothing would be quite so suave as a digital watch powered by plutonium.

The tiniest sliver of Pu-238 would be sandwiched between peltier cells to produce a miniature Radioisotope Thermoelectric Generator (RTG) -- the same technology that powers space probes. Picture the envy on your colleagues' faces when they realize your wristwatch is _nuclear powered_.

If you're concerned about safety, remember that Pu-238 was used as a long-lived battery for pacemakers. So it must be safe! [mitxela, Jun 18 2020]
