Clocks were invented before electricity. If an EMP took out all the electronics, a mechanical clock is still the best way to measure longitude at sea
If an emp took out all the electronics, the need to measure longitude at sea would not make my top ten concerns.
But I bet it would be in someone's top ten concerns
While true, most clocks are quarts oscillators These days so would die also. That said, love me a mechanical clock and have a skeleton watch I daily drive.
