## Abstract

A watch includes an hour hand and a minute hand, a dial including a plurality of time graduations indicating time by being pointed by the hour hand and the minute hand, and a dial plate including a graduation for predetermined information different from the time, and supported by a rotary shaft, wherein in plan view from a normal direction of the dial, the rotary shaft overlaps with a pointing graduation, which is one of the time graduations, and the predetermined information is indicated by the graduation of the dial plate in an extension direction of the pointing graduation.

## Claims

### Claim 1

A watch comprising:
an hour hand and a minute hand;
a dial including a plurality of time graduations indicating time by being pointed by the hour hand and the minute hand; and
a dial plate supported by a rotary shaft, the dial plate including graduations indicating predetermined information different from the time, wherein
in plan view from a normal direction of the dial, the rotary shaft overlaps with a pointing graduation that is one of the time graduations, and
the predetermined information is indicated by the graduation, of the dial plate, located in an extension direction of the pointing graduation.

### Claim 2 (depends on 1)

The watch according to claim 1, wherein
the pointing graduation is provided between the dial and the dial plate, and
the dial plate is transmissive.

### Claim 3 (depends on 1)

The watch according to claim 1, wherein
the rotary shaft is provided so as to penetrate through the pointing graduation,
the dial plate has a fan shape in plan view, and
the rotary shaft is provided in a vicinity of a center of the fan shape.

### Claim 4 (depends on 1)

The watch according to claim 1, wherein
the dial plate is provided between the dial and the pointing graduation.

### Claim 5 (depends on 4)

The watch according to claim 4, wherein
the time graduations are fixed to the dial by first and second legs, and
an interval between the first and second legs of the pointing graduation is shorter than intervals between the first and second legs of the time graduations other than the pointing graduation.

### Claim 6 (depends on 1)

The watch according to claim 1, wherein
the dial has an opening portion,
the dial plate is provided below the dial, and
the graduation of the dial plate is exposed from the opening portion.

### Claim 7 (depends on 1)

The watch according to claim 1, wherein
in plan view, the pointing graduation has a rectangular shape, and
the time graduations other than the pointing graduation also have a shape similar to the shape of the pointing graduation.

### Claim 8 (depends on 1)

The watch according to claim 1, wherein
the predetermined information is power reserve information, and
the graduation of the dial plate is an graduation indicating drivable time.
