An electronic watch includes a pointer, a receiver (GPS receiver) configured to receive positional identification information for identifying a current location, a magnetic sensor, and a controller configured to acquire destination information indicating a position of a destination, identify a direction of the destination, based on the positional identification information, an output of the magnetic sensor, and the destination information, identify a distance to the destination, based on the positional identification information and the destination information, and display a direction of the destination with the pointer. The controller switches the pointer to a set hand movement operation when the identified distance a threshold value.

A timepiece includes a display unit including a first indicating hand and a dial so as to display a time, in which the dial has a first scale having a number for showing an absolute value of a positive numerical value within a plurality of numerical values indicated by the first indicating hand, a second scale having a number for showing an absolute value of a negative numerical value within the plurality of numerical values, a first sign for showing that the numerical value indicated by the first indicating hand is positive, and a second sign for showing that the indicated numerical value is negative.

An electronic timepiece includes a magnetic sensor that serves as a magnetic detection unit, a GPS reception unit that serves as a reception unit receiving positional information of a current position, a time zone setting unit that sets a time zone, a specifying unit that specifies a declination angle based on the positional information of the current position, a decision unit that decides a direction of a due north based on an output of the magnetic sensor and a declination angle, and an azimuth display unit that displays the direction of the due north decided by the decision unit.

A magnetic field measuring apparatus includes a first processor, a second processor, a motion sensor and a magnetic field sensor. The second processor has higher processing capability than the first processor. The first processor makes the second processor perform certain processing. When it is determined that the state of motion measured by the motion sensor is at a predetermined level or more, the second processor performs a magnetic field correction setting operation as one of the certain processing. The magnetic field correction setting operation involves retrieving measurement values of magnetic field from the magnetic field sensor which are measured at different postures according to a change of the state of motion, and determining an offset correction value for the geomagnetic field based on the measurement values.

A magnetism sensor equipped timepiece includes a case including a built-in magnetism sensor, a band for the timepiece, and spring rods that attach the band to bows of the case. The spring rods are each formed of a pipe, a pin, and a spring. The pipes and the pins are each made of a non-magnetic material, and the springs are made of a non-magnetic material having elasticity.

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.

A navigation instrument including an orientation angle calculation unit, in particular the first and second orientation angles, wherein the orientation angle calculation unit is configured to be able to determine the first and second orientation angles in a given order and also in reverse order; and wherein the calculation unit is arranged to be able to choose between said given order and said reverse order, to calculate the first and second orientation angles, based on a comparison between an indicator of a risk of error, quantifying a risk of instability of said unit during the determination of the first and second orientation angles, and a predetermined threshold.
