ABSTRACT:
A wrist-portable apparatus has a case housing a rotational display member and an operational shaft for undergoing rotational movement and sliding movement relative to the case so that the operational shaft may be axially displaced between a pushed-in position, in which the operational shaft is pushed into the case, and a drawn-out position, in which the operational shaft is drawn out from the case. A clutch assembly transmits rotational movement of the operational shaft to the display member to rotate the display member when the operational shaft is displaced to the drawn-out position and releases the transmission of the rotational movement of the operational shaft to the display member when the operational shaft is displaced to the pushed-in position. A manual control stem is integrally connected to an end of the operational shaft and is disposed on a side surface portion of the case for controlling rotation of the operational shaft and displacement of the operational shaft to the pushed-in and drawn-out positions.
