Analog watches display time using mechanical hands that move over a dial with markers which represent hours and minutes. The term analog usually describes devices that feature a continuous, uninterrupted signal. In the case of analog watches this refers to the sweeping, continuous second hand, which is the result of internal mechanical movement, not digital electronics.
