摘要： In an analog electrical timepiece with a motor coil, when an external operating member is in a prescribed operating condition, the operating mode of the analog electrical timepiece is set to the data receive mode. Next, the analog timepiece generates a synchronization signal which is in synchronized to an external synchronization signal that is input from outside. Then, the analog electrical timepiece, when the operating mode is the data receive mode by the detection circuit, based on a synchronization signal and a data voltage signal that is a voltage signal induced around the motor coil by a data signal input from outside, generates and outputs a receive data.

摘要： When a frequency measurement unit measures the frequency of a temperature-sensing oscillation test signal and the frequency of a driving-pulse signal transmitted from an electronic apparatus via an coil electromagnetically coupled with a motor coil, a temperature-compensation data generation unit creates temperature-compensation data based on the frequency of the temperature-sensing oscillation test signal and the frequency of the driving-pulse signal. This temperature-compensation data is transmitted to an analog electronic timepiece via the coil. That is, a state of the analog electronic timepiece is measured in a non-contact manner and the temperature-compensation data obtained based on the measurement result is transmitted, whereby the analog electronic timepiece is adjusted in a state of being incorporated in an external casing.

摘要： An electronic timepiece with internal antenna maintains sufficiently high reception performance of circularly polarized waves even when having a metal external case. The timepiece has a cylindrical case; a crystal that covers the opening on the face side of the case; a drive mechanism that arranged inside the case; a metal antenna; and a dielectric. The antenna houses the drive mechanism and has a cylindrical side part, a bottom part that covers the opening on the back side of the side part, and an antenna electrode that contacts the inside of the side part. The back cover covers the back side of the case and is also the bottom part. The dielectric extends circumferentially to the side part, and contacts the antenna electrode in the face-back cover direction. A slot extending circumferentially is formed in the antenna electrode. Part or all of the slot is covered by the dielectric.
