Septagraph Perpétuel. In the eye of the temporal cyclone.
BorgeauD: an exclusive new complication.
The world première of a hitherto-unseen complication bearing the name of the Septagraph Perpétuel. Following the revival of the tourbillon, minute repeater and other key inventions in horological history, this tremendous feat of watchmaking achievement proves that not everything has been invented yet… A fascinating thought indeed.

The Septagraph Perpétuel is equipped with a time reserve indicator in the form of an arrow that empties itself of colour in the space of 90 minutes daily. Every day, the timepiece restores, in non-sequential fashion, that portion of time, which is rightfully yours. All the ninetyminute divisions, or one eighth-portions of a day, are to be found in the daylight hours between 6.00 a.m. and 6 p.m., according to a tempered average calculated back in Babylonian times and since adopted by other civilisations. The first division, situated between 6.00 a.m. and 7.30 a.m., does not count, since it is still night time and there are only seven days in a week. In order to indicate with precision that special portion of time, which occurs at different times every day, this highly complicated wrist watch has a dial inscribed with the different days of the week and the exact time at which the daily countdown begins. A jumping hand indicates the different start times every day.

A feat of watchmaking prowess with high added chronometric value.
On a craftsmanship level, the daily indication of these "restored" portions of time required a particularly complex chronometric approach in that each eighth of a day never occurs in chronological order. To rise to the challenge, the developers and engineers at BorgeauD Watches came up with Calibre BRG 11501, whose very design lends itself to a plethora of future enhancements and the addition of further complications. Complete with automatic winding, 25 rubies and 28,000 vph, this calibre is exclusively reserved for the BorgeauD brand and boasts a power reserve of 42 hours.

With respect to finishing techniques, Calibre BRG 11501 represents the essence of age-old fine watchmaking skills that are 100% Swiss. In a gesture combining the inimitable know-how of the valleys of Val de Travers and Joux, it undergoes a myriad traditional manual operations: circular-grained finishes, chamfered bridges, gently sloping collars, elegantly engraved and polished using a subtle treatment.

The distilled essence of aesthetics, the initiatory path of time.
An object of sublime aesthetics, affixed to a dial whose mysterious depths elegantly conceal an assembly of seven pieces in three dimensions, the openwork arrow, or "time reserve indicator", gently marks the passing of your daily window of time. Adorning the engraved and snailed dial, a circle of Roman numerals leads the dance, except for the figures 7 and 8, whose tips are faintly concealed by a counter specific to the Septagraph Perpétuel. At the top of the arrow, the letters S and P, signifying Septagraph and Perpétuel, obey the rules of aesthetic proportion. Two initials that go beyond the chronometric dimension and excite our mystical curiosity. But what if those eight divisions in the day, doubtless part of a natural rhythm, or planetary cycle, could be transformed into a Hedonist's delight? The true function of the Septagraph Perpétuel is to offer you time…

Born and bred in Fleurier and having spent a childhood filled with the sights, sounds, smells and legends of the watchmaking workshops. A legendary 19th century name in the Comtois watchmaking landscape hase been revived. Preserving the historical map intact, he creates a bridge between two valleys steeped in watchmaking history and, with the invention of the Septagraph Perpétuel, invites the world's connoisseurs to navigate the fascinating and hitherto-uncharted path of initiatory time…

The time reserve indicator. Every day, in non-sequential fashion, the Septagraph Perpétuel starts counting down 90 minutes of restored time (1 1/2 hours, 1/8th of a day), according to astronomical observations of 3000 years old.
