A user can easily identify the content of data (the value or the state of the data), such as a credit balance, stored in a contactless IC module provided in a wrist-watch device having a communication function. A timepiece control unit 14 of a timepiece module 10 transmits a confirmation command for the data, such as the credit balance, to a contactless IC module 60 every determination cycle period TSP, and receives the data stored in the contactless IC module 60 . When the value of the stored data (for example, the amount of balance) becomes smaller than a predetermined value, the timepiece control unit 14 causes a second hand to perform an irregular movement noticeably different from the regular timing movement. Accordingly, the user is able to easily identify the data content (for example, insufficient balance).
