Abstract
A timepiece has an ordinary time measuring section including an ordinary time display unit for measuring an ordinary time and time information (i.e., chronograph) measuring sections including chronograph displays for measuring time information other than the ordinary time (i.e., chronograph information). The timepiece is configured such that the ordinary time display unit and the chronograph display units, are disposed on a display surface of the timepiece without overlapping each other.
