Breguet Classique Hora Mundi

This watch can memorize two separate time-zone settings. Once the watch has been correctly set to the two desired time-zones, one can instantly toggle between the two time-zones by pressing the button at the 8 o'clock position, in what Breguet calls the "INSTANT-JUMP". Ingeniously the watch not only memorizes the different time-zones, it also memorizes the AM/PM & the date correctly adjusting these complications as well according to the desired time-zone. In essence this watch "memorizes" both time-zones & its associated settings, with a push of a button the user can toggle between the two desired time-zones.
