            Offered with a dial that represents the Americas, Europe and Africa or Asia and Oceania, this mechanical watch is the first to feature a time zone with a memory function that changes instantly.
                          This function enables travellers to simply display the time from two pre-selected time zones, transitioning from one to the other instantly using the pusher. It goes without saying, of course, that this does not disrupt the functioning of the watch, the precision of which, when the time is set, is ensured by a stop seconds system. This time zone change acts not only on the time but also on the date, synchronised by means of a calendar “tracking” system, in addition to the day/night indication.
