This paper is about an electronically controlled mechanical watch that has an electronic regulator in place of the usual mechanical regulator. This electronic regulator consists of a generator, a rectifying circuit, a control circuit, and a crystal oscillator. While conventional mechanical watches are accurate to within 10 to 20 seconds per day, a mechanical watch with an electronic regulator is accurate to within one second per day. There are two points in the development of the electronic regulator. The first point is the development of a generator and a rectifying circuit that can efficiently convert mechanical energy from the barrel into electrical energy. The second point is the development of a control circuit that keeps generating electricity while the magnetic brake is applied.
