Early sailors used the sun and constellations to fix longitude and latitude before they had clocks. In 1761, John Harrison designed and built a "sea watch" that was accurate to 25 seconds in a trip across the Atlantic. The problem was the change in temperature, pressure and humidity as the ships sailed.

How was accurate time established before electronic communication?
Pocket watches, wrist watches, grandfather clocks, and large church clocks do not actually require electronic powering. They are put together using gears and simple machines; in other words they are mechanical and not electronic.
