This mechanical watch, which took three years to develop and has been awarded four patents, features a dual time zone with memory and instantaneous change.
This technical feat is made possible by the manipulation of the pusher and crown. After setting the first city, the time and the date, all you need to do is set the second city. The mechanism then calculates the time and date using a clever system of cams, hammers and an integrated differential. By pressing the push-piece, it is possible to move from one end of the planet to the other, without disturbing the precise running of the watch. Aesthetically, the dial on this model, available in white or pink gold, offers an interpretation of the world map, constructed by superimposing different plates, notably in gold or sapphire.

Seconds display
The seconds display makes it possible to follow the passage of time with precision. Depending on the construction of the movement, it may take the form of a central seconds hand or an off-centred small seconds display, integrated into the architecture of the dial.
Day/night indication
The day/night indicator distinguishes daytime and night-time hours on the dial. Both functional and visual, it notably accompanies 24-hour displays or complications related to time zones.
Calendar
The calendar displays the date on the dial, generally by aperture, hand or disc. Simple in appearance, this indication requires precise integration both into the movement and into the balance of the dial.
Second time zone
The second time zone makes it possible to display the time in two different places simultaneously. This complication makes it easier to read time while travelling, while preserving a clear indication of the reference time.
Bevelling
Bevelling consists in chamfering and then polishing the edges of the movement components. This finish highlights the contours of the parts, catches the light and reveals the precision of the work devoted to the smallest details.
Stretching / dressing
Stretching and dressing prepare or finish metal surfaces through the regular working of the material. These operations create clean, flat and even surfaces, essential both to visual quality and to assembly precision.
Guilloché
Engine-turning engraves regular patterns into the material using a hand-operated lathe. At Breguet, this expertise structures the dial, catches the light and reinforces the legibility of the indications.
Perlage
Perlage consists in applying small regular overlapping circles to the movement components. This decorative finish creates a luminous texture and highlights the care devoted to surfaces that are usually only scarcely visible.
