The invention provides a wireless mouse-type electronic watch comprising a watchband, an electronic watch housing, a watch display screen installed on the outer surface of the electronic watch housing, and a circuit board installed in the electronic watch housing. A photoelectric assembly is installed on the end face of the electronic watchband opposite to the watch display screen. A left button and a right button are fixed on the two sides of the photoelectric assembly on the watchband, respectively. Power of the circuit board of the electronic watch is derived from a power end of a mouse chip circuit. The signal lines of all parts are integrated into the right band of the watchband and then are connected with the circuit board. The wireless mouse-type electronic watch may control and manipulate a computer and regularly arranges all functional parts, including the left button, the right button, the photoelectric assembly, and other assisted parts, on the electronic watch. Therefore, wearing the electronic watch, an operator may use the functions of an electronic watch and achieve manipulation and control of the computer.
