After creating a one-off edition in titanium in 2017, this year Bulgari presented the Octo Grande Sonnerie in rose gold.
This Haute Horlogerie timepiece features Grande and Petite Sonnerie, Minute Repeater, Westminster Chime functions, as well as a Tourbillon system.
The 44 mm rose gold case is characterized by a titanium case middle while the bezel and the caseback are both sandblasted.
To guarantee a perfectly audible and clear sound, the case was designed as a ‘sound box’ serving to optimise the sound as well as its diffusion. The case middle features striped lateral grooves which combine with a circular inner tunnel housed in the case middle and surrounding the movement. Both the amplification and the propagation of the sound are thus enhanced, while reducing the weight of the watch.
The decision to secure the movement to the case by internal “ears” (wings) was a deliberate choice for functional reasons: this construction contributes to optimise the transmission of the vibrations generated by the striking mechanism. Among the other innovations applied to this creation, the striking mechanism is activated not by a sliding bolt, but instead via a pusher which thereby ensures water resistance to 30 metres / 100 feet. Rotating selectors serve to choose between Strike/Silence and Grande Sonnerie/Petite Sonnerie modes.
Beneath the sapphire crystal, a single element – in the shape of a minute circle bearing rose gold hour-markers and two power-reserve segments respectively dedicated to the automatic movement and the striking mechanism – ensure an unobstructed view of the 3 Hz (21,600 vph) BVL 703 Caliber. The power reserve of the movement is 48 hours while the striking mechanism has an autonomy of 24 hours in Grande Sonnerie mode or 28 hours in Petite Sonnerie mode. Like the entire dial, the rose gold hour and minute hands are also skeletonized.
The back of the case is fitted with a sapphire crystal pane to reveal the tourbillon mechanism.
Completed by a rubber-coated alligator leather strap with a rose gold folding clasp, the Bulgari Octo Grande Sonnerie Ref. 102865 is a one-off edition. Price on request. bulgari.com
