The time display synchronized with the displayed clock 10 and having no deviation can be performed. Furthermore, even if the mobile phone 100 is provided with the analog quartz clock 50, the number of circuits for clocking can be reduced to one, so that the cost can be reduced.
[0019]
Next, the configuration of the movement 5 included in the analog quartz watch 50 and the mounting of the movement 5 on the mobile phone 100 will be described. FIG. 4 is a top view showing a mechanical configuration of the movement 5, and FIG. 5 is a sectional view thereof. As shown in FIGS. 4 and 5, the movement 5 is independently provided with a drive mechanism for driving the second hand 512 and a drive mechanism for driving the minute hand 513 and the hour hand 514. More specifically, the movement 5 includes, as a driving mechanism for driving the second hand 512, a second rotor 500a made of a permanent magnet, a second stator 500b made of a highly permeable material provided around the second rotor 500a, and a second A second electromagnetic motor 500 including a second coil block 500c for generating a magnetic field in the second stator 500b in response to a clock signal from the motor drive circuit 34; a fifth wheel & pinion 506 interlocked with the rotation of the second electromagnetic motor 500; A fourth wheel 507 that drives the second hand 512 in conjunction with the second wheel 506 is provided.
