Mechanical clock

A mechanical clock was an instrument for indicating time that had a dial numbered one through twelve, and moving hands. Although such devices were considered ancient by the time of the First Order–Resistance war, bomber pilots kept describing the relative direction of objects using the analogy of a 12-hour mechanical clock. For example, a starfighter coming from directly in front and above the bomber pilot would be coming from "12 high," while "6 low" referred to a fighter coming from the ground and behind.
