Breguet is launching this week the Classique Quantième Perpétuel 7327, the latest interpretation of the perpetual calendar complication from the luxury watchmaker.

Presented in 18K white or rose gold, the new reference 7327 embodies the core values of the brand: a timepiece that remain user-friendly despite the extreme complexity of its mechanisms.

Originating from the 18th century, the perpetual calendar function exhibits the precise date while considering the variable length of the months and the leap-year cycle. To achieve this, the watch's movement necessitates a four-year mechanical "memory" of 1,461 days. 

The mechanism is based on a gearing system from the hour's wheel and a large central lever that impels the entire movement each day. 

To perform these operations while also offering a light and slim timepiece, Breguet chose its self-winding Calibre 502 integrating it with an additional calendar mechanism. At just 4.5 mm thick, the 502.3.P movement remains one of Breguet's thinnest. Its barrel is open, contributing to its slenderness while guaranteeing constant, powerful energy. Its gold oscillating weight is off-centred to provide maximum space for the movement's main components, enabling it to be integrated to a minimum thickness. 

This 294-component movement operates at a frequency of 3 Hz and has a 45-hour power reserve. It is equipped with a flat silicon balance-spring and an inverted straight-line escapement with silicon horns. In addition to being resistant to corrosion and wear, silicon is insensitive to the influence of magnetic fields and improves the watch’s precision.

Thanks to a sapphire case back, it is possible to admire the outstanding finishes of the movement: the gold oscillating weight is hand-engraved on a rose engine with a circular barleycorn motif, the bridges and other components are adorned with Côtes de Genève and chamfered edges. 

The fluted caseband of the 39 mm x 9.13 mm case integrates the correctors for the various calendar functions. These indications are elegantly arranged on the silvered gold dial, which boasts a Clous de Paris hobnail pattern that was hand-engraved using a rose engine.

Positioned between 1 and 2 o’clock, the moon phase display showcases a hand-hammered moon that set against a blue lacquer background composed of spangles that emulate a starry sky.

The day, date and leap year indicators are harmoniously entwined at the base of the dial. A quarter-circle bewteen 10 and 11 o’clock indicates the months via a retrograde hand. The hours and minutes are indicated by the traditional eccentric “moon” tip hands made of blued steel. 

The secret Breguet signature, created by the founder in 1795, appears twice on the dial: once between 11 and 12 o'clock, and again between 12 and 1 o'clock.

The new Breguet Classique Quantième Perpétuel 7327 is paired with a midnight blue strap for the white gold model (ref. 7327BB/11/9VU) and a brown strap for the rose gold one (ref. 7327BR/11/9VU). For both versions, the suggested retail price is Euro 86,600. breguet.com
