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.
Minute repeater
The minute repeater strikes the hours, quarters and minutes on demand. One of the most exacting complications, it transforms time into an acoustic indication through a highly precise striking mechanism.
Passing strike
The passing strike automatically marks the hour or the quarters, without any action from the wearer. This complication makes time audible at regular intervals, thanks to a striking mechanism integrated into the movement.
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.
Grand Feu enamelling
Grand Feu enamelling consists in applying enamel and firing it at very high temperatures until a stable, luminous surface is obtained. This expertise demands exceptional mastery, as each firing can either reveal the dial or permanently compromise it.
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.
