Claims (13)

1. A timepiece comprising:

a main plate;

a rotating plate rotatable relative to the main plate around a predetermined central axis of rotation;

a gear rotatably supported on the rotating plate and rotatable in synchronization with rotation of the rotating plate with respect to the main plate; and

a decorative body linked with the gear and movable along a first direction while revolving around the predetermined central axis of rotation, the first direction extending radially from the predetermined central axis of rotation when viewed from the rotating plate,

wherein the rotating plate is provided with pin members for revolution with the rotating plate around the predetermined central axis of rotation, the pin members being configured to come into contact with the decorative body to restrict the decorative body from moving in a second direction relative to the rotating plate and guide the decorative body to move in the first direction relative to the rotating plate while revolving around the predetermined central axis of rotation, wherein the second direction extends orthogonally to the first direction when viewed in an axial direction of the predetermined central axis of rotation, and

wherein the rotating plate is provided with a pair of rails arranged to guide the decorative body to move in the first direction.

2. The timepiece according to claim 1 , wherein the decorative body is disposed on a rear side of a dial and movable to protrude radially outside from the dial when viewed from the front.

3. The timepiece according to claim 1 , wherein the main plate is provided with a tooth part arranged in an arcuate manner around the predetermined central axis of rotation, and the gear is configured to mesh with the tooth part.

4. The timepiece according to claim 1 , wherein the decorative body is configured to come into contact with the pin members at at least two points away from each other in the first direction.

5. The timepiece according to claim 4 , wherein the pin members come into contact with the decorative body on an opposite side of the decorative body from the rotating plate.

6. The timepiece according to claim 5 , wherein the decorative body is in contact with the pin members at at least two points away from each other in the first direction.

7. The timepiece according to claim 1 , wherein the gear is provided with a guide pin protruding toward the decorative body at a position eccentric with respect to a center of rotation of the gear, and the decorative body has a guide groove extending in a direction intersecting the first direction, the guide pin being inserted into the guide groove.
