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_.
Another use of Pu-238

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]
