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.

摘要： A positioning device has a reception unit for receiving navigation messages transmitted continuously in a time series from positioning information satellites orbiting the Earth and determines the location of the positioning device based on the navigation messages received by the transmission unit. Each navigation message is segmented into a plurality of data transmission blocks that are transmitted sequentially, a portion of the data transmission blocks carry almanac data containing orbital information for all positioning information satellites including the positioning information satellite transmitting the received navigation message, and the data transmission blocks carrying the almanac data are transmitted non-contiguously. The positioning device also has signal discrimination unit for identifying the start of receiving a data transmission block containing the non-contiguously transmitted almanac data, and identifying the end of receiving the data transmission block containing the almanac data. The reception unit intermittently receives the signals of the data transmission blocks containing the almanac data by receiving the navigation messages in the reception time of the data transmission blocks containing the almanac data identified by the signal discrimination unit.
