- Winding Manual winding
The power reserve for this manually-wound watch is visible on the dial at 10 o’clock as well as on the back.
In line with the codes of the collection, it features a movement with a 50-hour power reserve. Its smaller-sized dial, hand-engraved on a rose engine, makes it possible to admire almost all of the components on both sides of the central plate, such as the bridges, gear train, escapement and the famous old-style pare-chute in hand-chamfered steel.

Power reserve indicator
The power reserve indicator displays the remaining autonomy of the movement before it needs to be wound. It makes it possible to monitor the energy available in the barrel, while adding a direct mechanical reading to the dial.
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.
Microblasting
Microblasting consists in projecting fine beads onto a metal surface in order to obtain a matte, even and slightly textured finish. This finish softens reflections and enhances the contrasts with polished or satin-finished surfaces.
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.
