Abstract

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.

First claim

What is claimed is:

1. An electronic watch comprising:
a dial having at least one hand;
a dial ring disposed on an outer circumference of the dial and including a plurality of markings dividing the dial ring into 100 segments;
an information display part disposed on the dial and having a first area, a second area, a third area, a fourth area, a fifth area, and a sixth area, the first area, second area, and third area indicating an altitude display mode, a compass display mode, and a barometric pressure display mode, the altitude display mode displaying an altitude, the compass display mode displaying a direction, and the barometric pressure display mode displaying a barometric pressure, the sixth area being disposed within the fourth area and adjacent to the area containing the first area, the second area, and the third area, and an area containing the first area, the second area, and the third area being adjacent to an area containing the fourth area and the fifth area;
a first pointer separate from the at least one hand that indicates the altitude display mode by pointing to the first area, indicates the compass display mode by pointing to the second area, and indicates the barometric pressure display mode by pointing to the third area in the information display part; and
a second pointer separate from the at least one hand indicates an operating status of the electronic watch by pointing to the fourth area, indicates a remaining battery of the electronic watch by pointing to the fifth area, and indicates that a control unit is executing a measurement corresponding to the display mode displayed by the first pointer by pointing to the sixth area in the information display part,
wherein the first area, the second area, and the third area of the information display part are arranged in an order of the first area, the second area, and the third area in a turning direction of the first pointer, and
the at least one hand indicates a measurement result obtained in a mode indicated by the first pointer by pointing to at least one of the plurality of markings on the dial ring.

2. The electronic watch according to claim 1 , further comprising:
a drive unit that turns the first pointer; and
a control unit that controls the drive unit so that the first pointer points to the first area when a display mode is the altitude display mode, the first pointer points to the second area when the display mode is the compass display mode, and the first pointer points to the third area when the display mode is the barometric pressure display mode.

3. The electronic watch according to claim 1 , wherein the first pointer and the second pointer coaxially turn.

4. The electronic watch according to claim 1 , wherein the second pointer moves by an angle obtained by division of 360° by 4n where n is a natural number less than 15.

5. The electronic watch according to claim 1 , wherein the information display part is a subdial positioned on the dial, the information display part being divided into quadrants in an order of first through fourth quadrants starting at a twelve o'clock position and moving clockwise around the subdial, and
the first area, the second area, and the third area are positioned in the first and second quadrants on the subdial.

6. The electronic watch according to claim 1 , further comprising a seventh area and an eighth area for indicating a time display mode and an optional display mode,
wherein the information display part is a subdial positioned on the dial, the information display part being divided into quadrants in an order of first through fourth quadrants starting at the twelve o'clock position and moving clockwise around the subdial,
wherein the first area, the second area, the third area, the seventh area, and the eighth area are arranged in an order of the seventh area, the first area, the second area, the third area, and the eighth area clockwise as the first pointer turns,
the first, the second, the third, the seventh, and the eighth areas are arranged in the first and second quadrants, and
the optional display mode displays biological information of a wearer.
