Abstract

A timepiece includes an hour hand and a minute hand, a dial in which a cutout portion is formed, time scales for indicating the time of day disposed at the dial, a plate member disposed at a back side of the dial, and an auxiliary hand member disposed at a position of the plate member corresponding to the cutout portion of the dial in a plan view. The auxiliary hand member functions as another time scale for indicating the time of day and indicates information other than the time of day. The auxiliary hand member as another time scale is located farther away from the plate member than the time scales.

First claim

What is claimed is:

1. A timepiece comprising:
an hour hand and a minute hand;
a dial in which a cutout portion is formed;
a plate member disposed at a back side of the dial, the plate member being disposed at a position corresponding to the cutout portion of the dial in a plan view as viewed in a direction along an axis of the hour hand and the minute hand;
time scales for indicating the time of day disposed at the dial or the plate member; and
an auxiliary hand member disposed at a position of the plate member corresponding to the cutout portion of the dial as viewed in the plan view, and the auxiliary hand member is configured to:
function as another time scale for indicating the time of day; and
indicate information other than the time of day,

wherein the auxiliary hand member as the another time scale is located farther away from the dial than the time scales.

2. The timepiece according to claim 1 , wherein
the plate member includes the time scales for indicating the time of day by being indicated by the hour hand and the minute hand, and
the dial has a plurality of openings at positions corresponding to the time scales.

3. The timepiece according to claim 2 , wherein
the auxiliary hand member and the time scales are coated with a fluorescent coating material.

4. The timepiece according to claim 2 , wherein
as viewed in the plan view, the auxiliary hand member has a same shape as at least one of the time scales.

5. The timepiece according to claim 1 , wherein
the dial includes the time scales for indicating the time of day by being indicated by the hour hand and the minute hand.

6. The timepiece according to claim 5 , wherein
the auxiliary hand member and the time scales are coated with a fluorescent coating material.

7. The timepiece according to claim 5 , wherein
as viewed in the plan view, the auxiliary hand member has a same shape as at least one of the time scales.

8. The timepiece according to claim 1 , wherein
the plate member is provided with an information scale indicated by the auxiliary hand member.

9. The timepiece according to claim 1 , wherein
the auxiliary hand member is provided with an indication mark indicating the information.

10. The timepiece according to claim 1 , wherein
as viewed in the plan view, a position of a rotation axis of the auxiliary hand member is different from a center position of the auxiliary hand member.

11. The timepiece according to claim 1 , wherein
the auxiliary hand member includes an auxiliary hand for indicating the information, and the another time scale for indicating the time of day by being indicated by the hour hand and the minute hand.

12. The timepiece according to claim 1 , wherein
the auxiliary hand member is configured to indicate a battery residual amount as the information.
