A wristwatch comprises an ID Tag (data carrier) function applied to an RF-ID system. A watch main body comprises a reinforce resin-based case having band attachments to which wrist bands are engaged, and a resin-based bezel cover covering the upper section and outer periphery of the case. The case incorporates a display member composed of a fixing member, a resin-based display frame member, a hard glass member, and a waterproof packing, and a circuit member composed of a synthetic rubber-based module cover member, a module fixing member, a module and a module cover member. The case is sealed with a bottom cap member formed of a magnetic material via a waterproof packing, and is further covered with a resin-based case cover. A module comprises module housing members, a watch LSI substrate, a data carrier IC substrate having a data carrier IC that incorporates a control circuit for encoding/decoding and authenticating a transmitting/receiving signal and a data memory storing ID, and a data carrier antenna coil connected to the data carrier IC substrate and assembled at the outer periphery of the watch LSI substrate.
