Disclosed is an electronic timepiece, including: a tilt switch mounted in a predetermined position; and at least one processor that changes an operation mode of the electronic timepiece, based on a duration for which there is no change in an output signal of the tilt switch, from a normal mode to a first power saving mode in which power consumption is suppressed more than in the normal mode.

A control method, a computer-readable medium, and an electronic device are provided. The control method includes: detecting a connection state of a first electrode and a second electrode in an electronic device, where the connection state includes conductive connection and conductive disconnection; and adjusting a state of the electronic device based on the detected connection state.

A control method and an electronic device are provided. The electronic device includes: a housing having an accommodating space, where the housing is provided with a recess around the accommodating space, and a first electrode and a second electrode are disposed on a bottom surface of the recess; and a bezel, where at least one part of the bezel is disposed in the recess. When the bezel is located at a first position of the recess, the first electrode and the second electrode are conductively connected; and when the bezel is located at a second position of the recess, the first electrode and the second electrode are conductively disconnected.

An input mechanism, such as a crown, detects amounts of applied force. In various examples, an assembly including an input mechanism has an enclosure; a stem coupled to the enclosure such that the stem is rotatable, translatable, and transversely moveable with respect to the enclosure; a sensor, coupled between the stem and the housing, to which force is transferred when the stem moves with respect to the housing; and a processing unit coupled to the sensor. The processing unit is operable to determine a measurement of the force, based on a signal from the sensor.

An electronic device comprises: a housing; a cover material; a crown; a processor; and an optical proximity sensor comprising: a first light emitter; a second light emitter; and one or more light detectors. The one or more light detectors comprises a first light detector aligned with the first light emitter and the second light emitter in a first direction, the first light detector configured to receive a first amount of light from the first light emitter and configured to receive a second amount of light from the second light emitter. The processor is configured to determine a distance of an object to the optical proximity sensor or to the crown in a second direction, different than the first direction, based on the first amount of light and the second amount of light.
