An object is to provide a pointer driving motor unit which can easily control driving of a pointer of a time piece by a stepping motor, a multifunctional electronic device, and a control method of a pointer driving motor unit. A pointer driving motor unit includes: a supporting body; a stepping motor which rotates a pointer that is supported to be rotatable with respect to the supporting body; a plurality of input portions which include a first input portion into which a first instruction signal is input from a main control portion, and a second input portion into which a second instruction signal is input from the main control portion; and a control portion which is provided in the supporting body, outputs a first driving signal that drives the pointer by a first operation to the stepping motor based on a result of comparing the first instruction signal and a predetermined threshold value with each other, and outputs a second driving signal that drives the pointer by a second operation to the stepping motor
