There is a very high correlation between needing to know the exact time of day and having easy, commoditized access to electricity.
If you don't have electricity, and you are not navigating an antique wind-powered ship, you probably don't need a mechanical timepiece.
Also, I recall, from way back in the 1980s, a digital clock that was "powered by a potato", using zinc and copper probes. Even if we lost all grid power, and solar cells, and low-head hydro, we could still manage a zinc-copper cell battery.

Didn't you see that episode of Breaking Bad?
