The hour indication is complemented by information given by a perpetual calendar.
This feature displays the exact date, taking into account the variable length of the months and the leap-year cycle. To accomplish this feat, the movement has a mechanical “memory” of four years, or 1,461 days. This complexity has not prevented Breguet from creating one of the thinnest movements it has, with a thickness of just 4.5mm. In terms of aesthetics, the Classique 7327 features the finest "Clous de Paris" guilloché. The moon phase is hand-hammered and sits in a sky coated in sparkling blue glitter lacquer.

Moon phase
The moon phase reproduces the progression of the lunar cycle on the dial. A complication that is both astronomical and decorative, it combines the reading of time with a poetic representation of the sky.
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.
Straight stripes
Straight stripes are a decorative finish formed of regular parallel bands on the movement components. They structure the surface, soften reflections and highlight the geometry of the bridges.
Stretching / dressing
Stretching and dressing prepare or finish metal surfaces through the regular working of the material. These operations create clean, flat and even surfaces, essential both to visual quality and to assembly precision.
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.
