FIELD: physics.
SUBSTANCE: method is carried out by facilitating automatic movement of movable elements of a clock face or clock case in a region visible to an observer through automatic actuation thereof during temperature changes on the entire or a certain part of the surface of the case, e.g., closing the clock face, when worn on the hand - opening the clock face or during temperature changes on a clock worn on the hand of a user and temperature of a clock taken off the hand of a user; the heat-sensitive drive for movable elements of a clock face and/or case is configured for automatic actuation of movable elements of a clock face and/or case during change in temperature of the surface of the case, while allowing automatic opening/closing of the clock face, opening/closing of separate parts of the clock face, opening/closing of clock face pointers, movement of elements on the clock face, movement of elements of the case closing/opening the clock face. The clock has the heat-sensitive drive described above, and actuation of the movable elements of the clock face and/or case is carried out through the heat-sensitive drive while allowing automatic actuation of the movable elements of the clock face and/or case during change in temperature of the surface of the case.
EFFECT: broader functional capabilities of the clock.
