The first mechanical watch to feature a time zone with a memory function and instant time change is decorated with diamonds and sapphires.
On this high jewellery model, the bezel, case band and lugs are set with more than 17 carats of baguette-cut diamonds and sapphires. On the technical side, this timepiece displays two pre-selected time zones, switching instantly from one to the other with the touch of a button.

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.
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.
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.
Polishing
Mirror polishing consists in working the surface until a perfectly smooth and brilliant reflection is obtained. This finish requires great regularity in order to reveal the material without distorting the angles or volumes of the component.
