Abstract

An electronic timepiece includes a second hand, a dial having a display area provided with a plurality of markings corresponding to the second hand, and a display controller that controls driving operation of the second hand to cause the second hand to display calendar information. The display area, when viewed from a timepiece front side, is divided by two straight lines that pass through a rotating shaft of the second hand and are perpendicular to each other into four divided areas. Each of the divided areas is related to years elapsed since a leap year, and each of the markings is related to the month. The display controller, when causing the second hand to display the calendar information, causes the second hand to point at one of the markings in one of the four divided areas to display the elapsed years and the month.

First claim

What is claimed is:

1. An electronic timepiece comprising:
an indicating hand;
a dial having a display area provided with a plurality of markings corresponding to the indicating hand; and
a display controller that controls driving operation of the indicating hand to cause the indicating hand to display calendar information,
wherein the display area, when viewed from a timepiece front side, is divided by two straight lines that pass through a rotating shaft of the indicating hand and are perpendicular into divided area,
one of the divided areas is related, as first calendar information, to years elapsed since a leap year,
each of the marking is related to second calendar information, and
the display controller, when causing the indicating hand to display the calendar information, causes the indicating hand to point at one of the markings in one of the four divided areas to display the elapsed years and the second calendar information.

2. The electronic timepiece according to claim 1 ,
wherein the second calendar information is a month.

3. The electronic timepiece according to claim 1 ,
wherein the second calendar information is a day or a date.

4. The electronic timepiece according to claim 1 ,
wherein the indicating hand is a second hand.

5. The electronic timepiece according to claim 1 , further comprising
a calendar wheel,
wherein the display controller controls driving operation of the calendar wheel to cause the calendar wheel to display third calendar information.

6. The electronic timepiece according to claim 1 , further comprising
a second indicating hand that differs from the indicating hand as a first indicating hand,
wherein the display controller, when causing the first indicating hand to display the calendar information, controls driving operation of the second indicating hand to cause the second indicating hand to point at one of the markings to display third calendar information.

7. A method for correcting a calendar of an electronic timepiece including an indicating hand, a dial having a display area provided with a plurality of markings corresponding to the indicating hand, and an operation section, the display area, when viewed from a timepiece front side, divided by two straight lines that pass through a rotating shaft of the indicating hand and are perpendicular to each other into four divided areas, each of the divided areas related, as first calendar information, to years elapsed since a leap year, each of the markings related to second calendar information, and when the indicating hand is used to display the calendar information, the indicating hand is caused to point at one of the markings in one of the four divided areas to display the elapsed years and the second calendar information, the method comprising:
correcting the elapsed years by causing the indicating hand to point at one of the four divided areas in accordance with operation performed on the operation section; and
correcting, after the correcting of the elapsed year, a month by causing the indicating hand to point at one of the markings in one of the divided areas in accordance with operation performed on the operation section.
