Abstract
A portable watch is equipped with a watch exterior member, a crown, a crown lock button, and an urging member. In a case band with which the exterior member is equipped, there are formed a crown mounting hole and a member mounting portion communicating with this hole and vertically perpendicular thereto. The crown is arranged in the hole. The crown has a crown shaft portion passed through the hole and a crown head portion continuous therewith. The crown shaft is provided with a lock groove continuous in the peripheral direction. The lock button accommodated in the mounting portion has a button head portion (operation end portion) protruding from the mounting portion. The button is movable between a lock position where it is engaged with the groove to constrain the crown and a lock canceling position where it is detached from the groove to cancel the constraint of the crown, and is arranged at the lock canceling position through a one-touch operation of the button head portion. The watch is characterized in that the button is arranged at the lock position by an urging member accommodated in the mounting portion.
