The set of LED lights includes at least three LED lights, which are equally spaced and electrically connected to a set of wires in series or in parallel. The control device can be a photosensitive control element or a manual control switch. The timepiece can further include a thermometer and a hygrometer located within the case frame.

A driving device includes a stepping motor having a rotor, a coil for rotating the rotor, and a processor that drives the stepping motor. The processor generates a driving pulse for rotating the rotor of the stepping motor to a prescribed position, and outputs the driving pulse to the coil; and generates a rotation assistance pulse for rotating the rotor of the stepping motor at a prescribed speed, and outputs the rotation assistance pulse to the coil, after outputting the driving pulse but before EMF is produced by the rotation of the rotor of the stepping motor caused by the driving pulse.

A timepiece including a GPS receiver that receives a radio wave from a positioning satellite, a time counter that performs a time count operation, and a processor, the processor being configured to: corrects a time count of the time counter in accordance with time and date information included in the radio wave from the positioning satellite received by the GPS receiver; acquires a temperature in the timepiece; acquires a voltage of a battery; and controls a receive operation at the GPS receiver in accordance with the temperature and the voltage.

An electronic watch having an altitude display mode of displaying an altitude, a compass display mode of displaying a direction, a barometric pressure display mode of displaying barometric pressure as display modes includes a dial face having an ALT area, a COM area, and a BAR area and a first pointer displaying the altitude display mode by pointing the ALT area, displaying the compass display mode by pointing the COM area, and displaying the barometric pressure display mode by pointing the BAR area. In the dial face, the ALT area, COM area, and BAR area are arranged in an order of the ALT area, COM area, and BAR area. In a turning direction of the first pointer, a distance between the ALT area and COM area and a distance between the COM area and BAR area are shorter than a distance between the ALT area and BAR area.

A smart watch comprises a case, a display device configured to present a user interface disposed in substantially all of a face of the case, a bezel around the display device configured to be rotated to select a mode of operation of the smart watch, and an analog first watch arm and an analog second watch arm disposed over the display, the second watch arm coaxial with the first watch arm. In a first mode of operation, the user interface presents a watch dial and control the first and second watch arms indicate a time of day first and second watch arms to indicate a time of day. In a second mode of operation, the user interface presents a dial and control the first and second watch arms form a pointer, the pointer configured to indicate a reading on the dial.

The invention relates to a capsule comprising a shell containing a transparent and thermally conducting liquid, particles having a thermochromic coating and particles having a photochromic coating, the thermochromic particles being bulkier than photochromic particles, the liquid being such that, within a first range of temperatures, its density is greater than the density of the thermochromic particles and than the density of the photochromic particles, and such that, within a second range of temperatures greater than those of the first range, the density of the photochromic particles is less than the density of the liquid, which is itself less than the density of the thermochromic particles.

A smart watch includes: a watch dial, a watch band, a monitoring apparatus, and a mechanical transmission apparatus; herein, sensors are set on both front and back surfaces of the watch dial; the watch band is made of hard material and has a multi-section structure; and beginning from a first section of watch band fixedly connected to the watch dial, each section of watch band is a hollow cavity structure that accommodates a next section of watch band; the monitoring apparatus is deployed within the watch dial; the mechanical transmission apparatus is set between the watch dial and the watch band, and is arranged to control extension or retraction of other sections of watch bands for automatically wearing or removal of the watch band. A smart watch automatic wearing method is further provided.
