Snow-set diamonds adorn the dial of this tourbillon model.
The Tourbillon is Breguet's flagship complication, created by its founder, A.-L. Breguet. The movement of this hand-wound model is engraved on the back with the words "Brevet du 7 Messidor An 9", which references the date of filing of the patent, and is equivalent to the Republican calendar of 26 June, 1801. On the front, the tourbillon is topped by a blued "B"-shaped bar, as are the iconic open-tipped Breguet hands. The decoration continues on the bezel, lugs and crown, which are adorned with diamonds.

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.
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.
Sunburst finish
The sunburst finish is a decorative finish composed of radiating lines extending from a central point. It animates the surface through circular reflections and brings relief to components or dials.
