Subsequent to making an erratic version in titanium in 2017, this year Bulgari introduced the Octo Grande Sonnerie in rose gold.
This Haute Horlogerie watch highlights Grande and Petite Sonnerie, Minute Repeater, Westminster Chime capacities, just as a Tourbillon framework.
The 44 mm rose gold case is portrayed by a titanium case center while the bezel and the caseback are both sandblasted.
To ensure a totally discernible and clear solid, the case was planned as a ‘sound box’ serving to enhance the sound just as its dissemination. The case center highlights striped horizontal sections which combine with a round internal passage housed for the situation center and encompassing the development. Both the intensification and the engendering of the sound are accordingly upgraded, while lessening the heaviness of the watch.
The choice to tie down the development to the case by inside “ears” (wings) was an intentional decision for utilitarian reasons: this development adds to advance the transmission of the vibrations produced by the striking system. Among different advancements applied to this creation, the striking instrument is initiated not by a sliding jolt, but rather through a pusher which subsequently guarantees water protection from 30 meters/100 feet. Pivoting selectors serve to pick between Strike/Silence and Grande Sonnerie/Petite Sonnerie modes.
Underneath the sapphire precious stone, a solitary component – looking like brief circle bearing rose gold hour-markers and two force save sections individually devoted to the programmed development and the striking system – guarantee an unhindered perspective on the 3 Hz (21,600 vph) BVL 703 Caliber. The force hold of the development is 48 hours while the striking component has a self-sufficiency of 24 hours in Grande Sonnerie mode or 28 hours in Petite Sonnerie mode. Like the whole dial, the rose gold hour and moment hands are likewise skeletonized.
The rear of the case is fitted with a sapphire precious stone sheet to uncover the tourbillon instrument.
Completed by an elastic covered crocodile calfskin lash with a rose gold collapsing catch, the Bulgari Octo Grande Sonnerie Ref. 102865 is an irregular release. Cost on solicitation. bulgari.com
