During the GENEVA WATCH DAYS 2021 event, Bvlgari unveiled the Octo Roma Central Tourbillon Papillon timepiece, which offers an original reading of time that is unique in the field of horological complications.
A metaphor inspired by the flight of the butterfly, the Papillon mechanism carries two independent retractable diamond-shaped hands positioned on a supporting disc. Each runs in turn along a 180-degree semi-circular minute track.
While the jumping hour appears in the window located at 12 o’clock, the minutes are indicated successively by each of the two hands. The first is positioned on the segment and thus signals the progression of the minutes, while the other remains in a retracted position throughout the path of the disc carrying them.
When the first hand reaches the 55th minute on the display segment, the other hand will gradually make a quarter turn to take a position parallel to the first on the 00-minute indication. The first hand will then move to the retracted position for the next 55 minutes.
The new Octo Roma Central Tourbillon Papillon watch features a patented high-precision mechanism integrated into its mechanical heart with a 24-hour jumping hour display by means of a disc on a ceramic ball bearing via an aperture located at 12 o’clock. At the end of the 60 minutes indicated by one of the “butterfly” hands, the disc jumps to display the new time in the aperture.
The Papillon device consumes less energy than the traditional minutes display, which has a positive impact on the power reserve. This model is driven by a hand-wound mechanical Manufacture movement, Calibre BVL 332, entirely designed and assembled in the finest tradition by the master-watchmakers of the Manufacture Bulgari. It features a 60-hour power-reserve indication on the back of the rose gold Octo Roma case.
