For this model, Breguet skeletonised its extra-flat automatic tourbillon movement that is 3 mm thick, showcasing its artisanal crafts.
The conception of the tourbillon had to be entirely rethought, giving rise to a unique architecture. Today, the Maison is going further, by removing 50% of the material from this already uncompromising movement. Also skeletonised, this 18-carat gold calibre precisely plays with the limits of physics, reminiscing that the watchmaker at Breguet, practices a real artisanal craft. Then comes the engraving, guilloché and anglage creating an extraordinary result.

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.
Tourbillon
Invented by Abraham-Louis Breguet in 1801, the tourbillon is designed to compensate for the effects of gravity on the regulating organ. By placing the escapement and the balance wheel in a mobile cage, it remains one of the House’s most emblematic complications.
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.
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.
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.
