摘要:
In a timepiece, moments of inertia of a first pointer and a second pointer that are for displaying first information and second information, respectively and that have a same rotation axis are the same. As a result, parts having identical specifications may be used in a drive mechanism of the first pointer and a drive mechanism of the second pointer. Further, color schemes of the first pointer and second pointer differ. As a result, a user may easily distinguish the first pointer and the second pointer.
