What is the difference between analogue and digital watches/clocks?

Analogue watches/clocks have a mechanism to indicate time by means of mechanical structures, such as a dial and hands (hand indication type), while digital watches/clocks have a mechanism to indicate time by means of electronic structures, such as a liquid crystal and LED (number display type).

"Digital" ("digit" as a noun), representing a finger, implies a thing that can be counted on fingers, which indicates a number. On the other hand, "analogue" originally means resemblance or similarity, which indicates a continuous quantity, as the antonym of "digital."
