    • 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.
    • 电子钟表包括秒针,具有设置有与二次手相对应的多个标记的显示区域的表盘以及控制秒针的驾驶操作以使秒针显示日历信息的显示控制器。 当从钟表前侧观察时,显示区域被穿过第二只手的旋转轴并且彼此垂直的两条直线分成四个分开的区域。 每个划分的区域都与闰年相关的年份相关,每个标记与月相关。 显示控制器在使秒针显示日历信息时,使秒针指向四个划分区域之一中的一个标记,以显示经过的年数和月份。

    • A perpetual calendar for a watch including a movement controlling the daily release, at the moment that the date changes, of a mechanism actuating a perpetual lever of this perpetual calendar is disclosed. The perpetual calendar includes a calendar mechanism, a daily countdown mechanism including a month-end adjustment mechanism, and a differential mechanism. The calendar mechanism is arranged to determine the duration of the current month and is updated at each current month change by the daily countdown mechanism. The differential mechanism is arranged to control, each day at the moment that the date changes, the motion of an additional adjustment cam comprised in the month-end adjustment mechanism, based on the current day of the month taken from the daily countdown mechanism, and also based on the current month duration taken from the calendar mechanism.
    • 披露了一种手表的永久日历,包括控制每日发布的动作,在日期变化的时刻,启动永久日历永久杠杆的机制。 永久日历包括日历机制,每日倒计时机制,包括月末调整机制和差异机制。 日历机制被安排为确定当前月份的持续时间,并在每个当前月份更改每日倒计时机制更新。 差异机制被安排为控制日期变化的每一天,基于从每日倒计时机制取得的当前日期,在月末调整机制中包括的附加调整凸轮的运动,以及 也是基于从日历机制获取的当前月份。
