The novelty is sculptured from 18K red gold or 950 platinum and demonstrates exceptional finishes. It catches the glance by its translucent lacquered dial. The dial shows off hours, minutes and seconds with help of central hands. The date is presented at 12 o’clock, while the city or time-zone indicator is at 6 o’clock. The large day/night display is featured between 3 and 4 o’clock.
The complicated Breguet watch represents the first mechanical timepiece that boasts an instant-jump time-zone display with synchronized date, day/night and city indications. Due to this function, the watch shows the time in two pre-selected time zones (from among the cities listed for the 24 time zones) and the watch wearer can instantly change from one time zone to the other pressing the combined crown/pushpiece at 8 o’clock. The accurate operation of the watch is not disturbed due to a stop second system. As for the date, it gets synchronized with help of a “tracking” calendar system.
The Breguet Classique 5717 Hora Mundi watch is also special due to its highly original date display that incorporates a dragging disc. It is presented via a window at 12 o’clock. The window shows three consecutive dates at once. To make the date reading as clear as possible, the dragging calendar system has been fitted with a tiny retrograde hand that is found beneath the dial and has in a small circle at its tip.
The circle frames the today’s date the moment it appears at the left side of the window, and until it disappears at the right. At midnight, the tiny hand jumps back to the left side to frame the date of the beginning day.
