Electronic watch

An electronic watch, comprising:

• a two-coil stepper motor including:
• a rotor magnetized into two poles or more in a radial direction of the rotor;
• a stator including:
• a first stator magnetic-pole portion and a second stator magnetic-pole portion, which are formed so as to oppose to each other through the rotor;
• and
• a third stator magnetic-pole portion, which is formed between the first stator magnetic-pole portion and the second stator magnetic-pole portion so as to face the rotor;
• a first coil to be magnetically coupled to the first stator magnetic-pole portion and the third stator magnetic-pole portion;
• and
• a second coil to be magnetically coupled to the second stator magnetic-pole portion and the third stator magnetic-pole portion;
• and
• a drive pulse generation circuit configured to output a drive pulse for driving the rotor to the first coil or the second coil,
• wherein the drive pulse includes a plurality of drive pulses,
• wherein the rotor is to be rotationally driven in increments of 360° due to a drive pulse train formed of the plurality of drive pulses, and
• wherein the electronic watch is configured to switch between a high-speed drive, in which the rotor is to be rotationally driven in increments of 360°, and a normal drive, in which the rotor is to be rotationally driven in increments of 180°, and
• wherein the rotor is to be driven in the high-speed drive at a frequency higher than in the normal drive.
