The subject invention is a timekeeping device having a dial with eight evenly spaced hour indicators and one hand rather than two, for indicating both hours and minutes. For optimal accuracy the spaces between the hour marks contain eleven evenly spaced marks that indicate five-minute intervals. At the top of the dial there are three numerals 12, 8, and 4. On the bottom side of the dial are the same three numerals 4, 12, and 8. The numbers are in such order that noon can be placed at the top or bottom and all times will read properly. Additionally, all PM numbers can be increased by 12 to form a 24-hour dial.

The present disclosure provides a timepiece including: an hour hand and a minute hand, a dial in which a cutout portion is formed, a plate member disposed at a back side of the dial, and an auxiliary hand member disposed at a position corresponding to the cutout portion of the dial in plan view as viewed in a direction along an axis of the hour hand and the minute hand, the auxiliary hand member being configured to function as a scale for indicating the time of day, and to indicate information other than the time of day.

A watch includes a timepiece movement including a mechanism for displaying a time period or season which includes a first wheel which is provided in order to turn once in thirty-one days for displaying a day of the month, and a second wheel for displaying another time period or season. The second wheel turns more quickly than the first wheel for displaying this time period or season, and the second wheel is provided in order to be displaced from the first wheel, at the rate of one turn in a period of time between 340 days and 380 days.

A trigonometric function display clock includes a clock face that has a center aligned with a central axis, axial markings aligned with an x-axis and a y-axis, and a secondary circle having a diameter equal to a radius of the axial markings. A first point on the secondary circle is aligned at the center of the central axis, and the secondary circle is configured to be rotatable about the first point. The secondary circle is configured to overlap and align with at least a portion of the axial markings as the secondary circle rotates about the first point.

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.

An electronic timepiece includes a power generator that generates electric energy, a power storage that stores the electric energy, a capacity detector that detects remaining capacity of the power storage, an operation unit, an operation detector that detects a measurement display operation for instructing the operation unit to display a measurement time, and a capacity display operation for instructing the operation unit to display the remaining capacity, an indicating hand that is used in displaying the measurement time and the remaining capacity, a drive unit that drives the indicating hand, and displays the remaining capacity after moving the indicating hand so as to indicate a preset reference position.
