Abstract
A timepiece has movable indicator hands for the analog display of current time. An ambient state, such as ambient light intensity, presence of a person in a room, or infrared radiation is sensed. Whether or not time indication is necessary is determined depending on the ambient state. If it is determined that the ambient state indicates that time indication is not necessary, then the movement of the indicator hands is stopped to conserve energy and reduce noise. When the ambient state indicates that time indication is necessary, the position of the indicator hands is adjusted from a stop position to a position indicative of current time.
