It is a rare example of a perpetual calendar that adjusts forward and backward in seconds over the quick corrector position of a single crown, even in the year 2100. The wearer can adjust Its hour hand instantly to a new local time using pushers (marked “+” and “-“) without taking the watch off the wrist or interfering with its timekeeping. A center-mounted arrow-tipped hand keeps track of the home or reference time. The oversized date, day, month and year change instantly, forward or backward, when the hour hand is moved to a new local time across the dateline by the pushers.
