Three versions of the dial are available, each representing one part of the world: the Americas, the European and African continents, or Asia and Oceania – six references in all.
This watch’s most iconic complication, however, is its instant-jump time-zone display system with synchronised date, day/night and city indications, a world first for a mechanical watch.
This function allows the traveller to easily display the time in two pre-selected time zones, changing instantly from one to the other simply by pressing a button, without disturbing the operation of the watch.
Changing the time zone affects not only the time, but also the date synchronised through a “tracking” calendar system – and the day/night indicator.
