Abstract

An electronic watch includes a reception circuit configured to receive a radio wave, a hand, an operation device, a storage unit configured to store a reception result of whether reception by the reception circuit succeeds or fails, and a reception controller configured to switchably set a reception permission state where reception is permitted and a reception inhibition state where reception is inhibited, wherein when first operation of the operation device is performed, the hand indicates a first position in a case in which the reception permission state is set and a reception result stored in the storage unit is a success, indicates a second position in a case in which the reception permission state is set and a reception result stored in the storage unit is a failure, and indicates a third position in a case in which the reception inhibition state is set.

First claim

What is claimed is:

1. An electronic watch comprising:
a reception circuit configured to receive a radio wave;
a hand;
an operation device;
a memory configured to store a reception result of whether reception by the reception circuit succeeds or fails;
a display controller configured to control the hand; and
a reception controller configured to switchably set a reception permission state where reception by the reception circuit is permitted and a reception inhibition state where reception by the reception circuit is inhibited, wherein
when a first operation is performed by operating the operation device,
the display controller controls the hand to:
indicate a first position in a case in which the reception permission state is set and the reception result stored in the memory is a success;
indicate a second position in a case in which the reception permission state is set and the reception result stored in the memory is a failure; and
indicate a third position in a case in which the reception inhibition state is set, and

the switching between the reception permission state and the reception inhibition state is performed by operating the operation device.

2. The electronic watch according to claim 1 , wherein
the hand is one of a plurality of hands configured to display time.

3. The electronic watch according to claim 1 , wherein
the operation device includes a crown and a button, and
the first operation is to operate the button in a state where the crown is at a zero-stage position.

4. The electronic watch according to claim 1 , wherein
the reception controller is configured to, when a second operation is performed by operating the operation device in a time display mode for displaying time with a plurality of hands,
transition to a mode that enables the switching of setting between the reception permission state and the reception inhibition state.

5. The electronic watch according to claim 4 , wherein
the operation device includes a crown and a button,
the first operation is to press the button in a state where the crown is at a zero-stage position,
the second operation is to press the button in the state where the crown is at the zero-stage position, and
the first operation and the second operation differ in a pressing time of the button.

6. The electronic watch according to claim 1 , wherein
after the switching from the reception inhibition state to the reception permission state,
the display controller controls the hand to indicate the first position or the second position in response to the reception result stored in the memory.

7. The electronic watch according to claim 1 , wherein
the reception controller is configured to:
perform reception by the reception circuit when the reception permission state is set and an automatic reception condition is satisfied; and
store a failure as the reception result in the memory without performing reception by the reception circuit when the reception inhibition state is set and the automatic reception condition is satisfied.

8. A control method for an electronic watch, the method comprising:
detecting that a first operation is performed by operating an operation device;
controlling, when the first operation is detected, a hand to:
indicate a first position in a case in which a reception permission state where reception by a reception circuit is permitted is set and a reception result stored in a memory is a success,
indicate a second position in a case in which the reception permission state is set and the reception result stored in the memory is a failure, and
indicate a third position in a case in which a reception inhibition state where reception by the reception circuit is inhibited is set;

detecting that a second operation is performed by operating the operation device; and
switching between the reception permission state and the reception inhibition state by operating the operation device when the second operation is detected.
