Breguet Reinterprets Their Perpetual Calendar

Breguet pays tribute to the past within its Classique collection through a reinterpretation of the perpetual calendar in two gold colours.

The latest Quantième Perpétuel 7327 by Breguet reflects the true essence of the brand: a timepiece that is simple to use for its wearer yet complex in its realisation. The mechanism is based on a gearing system from the hour’s wheel and a large central lever that drives the entire movement on a daily basis. For this reason, no less than 294 components are required to bring this model to life.

One of Breguet’s key objectives was to offer a light and comfortable timepiece and therefore, the Manufacture has opted for Calibre 502 with an additional calendar mechanism. At just 4.5 mm thick, the 502.3.P movement remains one of Breguet’s thinnest.

Its movement, which can be admired through the sapphire case back, highlights a skill dear to Breguet: decoration. The gold oscillating weight is hand-engraved on a rose engine with a circular barleycorn motif, the bridges are adorned with Côtes de Genève, and the other components are finished with chamfered edges and likewise with Côtes de Genève. This highly precise craftsmanship is performed by the artisans in the Manufacture located in the heart of the Vallée de Joux.

As fascinating on the movement side as on the dial, the new creation by Breguet features a timeless aesthetic, recalling the brand’s distinctive features in a contemporary spirit. The dial is adorned with a Clous de Paris hobnail pattern. Located between 1 and 2 o’clock, the moon phase has been designed to provide a strong sense of realism, notably thanks to its hand-hammered surface. Its sky is coated with a blue lacquer composed of spangles subtly revealing the stars depending on how the timepiece is turned.

Adjustments of the various dial indications are completed from several positions on the 39 mm case. A corrector stylus serves to adjust the day at 4 o’clock; the different moon phases between 4 and 5 o’clock, the date at 6 o’clock and finally the month and the year at 9 o’clock. The time is set via the crown located at 3 o’clock.
