An electronically controlled mechanical timepiece has first and second switches (121, 122) placed between an input terminal (22a) of a capacitor (22) and output terminals MG1 and MG2 of a generator (20), a third switch (130) placed between the output terminal MG1 and an input terminal (22b) of the capacitor (22), and a brake control circuit (55) enabled to control the switches independent of one another. Electric current is fed through the generator 20 by opening the switch (121) and closing the switches (122, 130). Thus, a rate measurement pulse is outputted therefrom. Consequently, rate measurement is easily achieved.
