An automatic winds a spring, while a kinetic charges a capacitor or battery.

The kinetic will keep time longer when not worn (it varies depending upon the model, but it can be for many months).

A diver labeled watch has been pressure tested to the stated maximum depth rating for a prolonged period (and other extensive tests to qualify as a diver).
