Patent ID: 7515112

Claim:
A radio wave controlled timepiece comprising: a case which includes an inner space having an opening communicated with an outer space; a light transmissible member which covers the opening of the case; an antenna which is installed in the inner space of the case, and which includes an elongated core and a coil wound around a center portion of the core, wherein the antenna is configured to receive a radio wave including time information; an antenna support member which is independent of the case and installed in the inner space of the case, and which includes two magnetic portions and a non-magnetic portion supporting the two magnetic portions independently of each other, wherein first and second end portions of the core of the antenna are magnetically coupled with the two magnetic portions, respectively; a time counting unit which is held by the antenna support member in the inner space of the case, and which is configured to count a time; a time display unit which is held by the antenna support member in the inner space of the case, and which is visible from the outer space through the light transmissible member, wherein the time display unit is connected to the time counting unit and is configured to display the time; and a time updating unit which is held by the antenna support member in the inner space of the case, and which is configured to update the time displayed on the time display unit, based on the time information included in the radio wave received by the antenna.
