DATOGRAPH大日历计时万年历腕表

The DATOGRAPH PERPETUAL is a wristwatch that combines a chronograph with a perpetual calendar. With indications of the date, day of week, month and leap year, this perpetual calendar is engineered to such a degree of accuracy that it requires no adjustment until the year 2100, when a one-day correction is needed. Conversely, its chronograph can stop times to an accuracy of one-fifth of a second. 探索DATOGRAPH大日历计时万年历腕表
