Breguet presents an exceptional piece, the kind that makes you daydream. And it does so by reworking its Double Tourbillon, launched in 2006. Now, we are finally told, the precious mechanism that moves the two tourbillons can be seen through a sapphire crystal dial, revealing the central differential gear train of the manually wound Calibre 588N. The pair of tourbillons, which share the upper bridge, rotate one revolution every 12 hours, each pivoting on the mainplate, which also pivots around a large central ball bearing. The tourbillons, of course, also each rotate on themselves, adjusting the movement's rate, thanks to the differential that connects them. The connected regulating organs thus make a double rotation, dragging the hour hand, formed by the bridge supporting the two tourbillons, along their course. The minutes, on the other hand, are indicated by a classical hand in the centre. Stripped bare, the inner side of the case middle emerges from the calibre, on which the hand-engraved shadow of the Roman numerals of the sapphire crystal hour circle stands out. The caseback bears an incredibly beautiful hand-engraved engraving depicting the Quai de l'Horloge building in Paris that was Abraham-Louis Breguet's first atelier The watch is fitted with a Stone strap in natural slate and rubber, with a triple folding clasp in platinum, the same material as the case.
