The hour indication is completed by a retrograde date that faces the off-centred dial at 12 o’clock.
Alongside the traditional Breguet hands that adorn the off-centred dial and indicate the hours and minutes, there is another hand distinguished by its astonishing architecture. Curved on the vertical plane, it has multiple levels enabling it to fly over the components of the movement, eventually reaching the date section between 3 and 9 o’clock. Its retrograde function enables it to return to 1, at the end of the month. It was none other than A.-L. Breguet who was one of the first to perfect the retrograde date complication, which he implemented on some of his famous creations.

Calendar
The calendar displays the date on the dial, generally by aperture, hand or disc. Simple in appearance, this indication requires precise integration both into the movement and into the balance of 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.
