This model enlivens an enchanted dance of the sun and moon in their desire to meet.
This model’s patented movement features a display with two dials, with one representing the hours and minutes in a traditional manner, and the second showcasing the complication that indicates the time of the day and the night. The sky is represented by a lapis-lazuli disc inlaid with natural white mother-of-pearl clouds, gold stars and a hand-engraved titanium moon. But the true star here is the sun, represented by the felloe of the faceted balance wheel that evokes the rays of the sun. It makes one rotation over the course of a full day, passing under the steel bridge that supports the mechanism and which faces the moon.

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.
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.
Hand engraving
Hand engraving consists in incising the material using traditional tools to create decorations, inscriptions or motifs. Each gesture calls upon the artisan’s expertise and gives the piece a unique character.
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.
