Breguet Classique Quantième Perpétuel 7327

The new 7327 Quantième Perpétuel (Perpetual Calendar) from the Breguet Classique collection pays tribute to the perpétuelle watches made by the brand’s eponymous founder.

In the 1780s, Abraham-Louis Breguet enjoyed great success with his perpétuelle watches with an à secousses (moving) oscillating weight enabling the calibre to react to the wearer’s body movements and thus automatically wind the mechanism as they walked. These watches often incorporated a calendar mechanism and it was also on these models that Breguet experimented with his first guilloché silvered dials.

The new Classique Quantième Perpétuel 7327 by Breguet is simple to use for its wearer yet complex in its realisation. To equip this timepiece, the Maison has opted for the Calibre 502 with an additional calendar mechanism.

Measuring just 4.5 mm in thickness, the 502.3.P Calibre provides a high level of performance despite its thinness. 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 self-winding movement is rhodium-plated, beats at a frequency of 3 Hertz 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.

This exceptionally decorated perpetual calendar movement can be admired through the sapphire case back. 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.

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.

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

The secret Breguet signature, created by the founder in 1795, appears between 11 and 12 o’clock as well as between 12 and 1 o’clock. Finally, 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.

Available in 18K white or rose gold, this new timepiece comes with a midnight blue strap for the white gold model and a brown strap for the rose gold version.
