Since 2010, Bulgari received many awards for its timepieces. Five out of six of their newest creations entered the final selection of the Grand Prix d'Horlogerie de Genève, the world's most prestigious watch awards. At the GPHG 2017, the Octo Finissimo Automatic and the Octo Finissimo Tourbillon Skeleton were the winners of the “Men’s watches” and “Tourbillon and escapement” categories, respectively. Several other international awards recognized the daring and innovative approach to watchmaking that Bulgari is demonstrating.
Bulgari is once again flexing its muscles with its latest creation, the Octo Grande Sonnerie Perpetual Calendar.
Combining two of the most exclusive complications, the Grande Sonnerie and the Perpetual Calendar, this is the single most complicated product created by the brand. It required more than one year of work to be completed.
Features include: Hours, Minutes, Tourbillon, Minute Repeater, Petite and Grande Sonnerie, Perpetual Calendar, Moonphases, and GMT function as well as movement and chime Power-Reserve indicators.
Equipped with four hammers, the in-house automatic calibre BVL 5307 sounds the hours, quarter-hours and minutes on demand. Beating at 3 Hz (21,600 vph), it offers a power reserve of 48 hours for the movement and 28 hours for the striking system.
The Perpetual Calendar features the full range of calendar indications: day, date, month and year along with moonphases.
Neither round, nor square, the case of the watch is crafted from rose gold with a sandblasted finish and has a diameter of 44 mm. The case middle is made in titanium with a black DLC (Diamond Like Carbon) surface treatment. Thanks to its resistance, lightness and low density, titanium offers the best possible chiming characteristics. Both sides of the watch have sapphire crystals. Water resistance is 30 metres / 100 feet.
A black alligator leather strap with a sandblasted 18kt rose gold folding clasp completes the watch. A piece unique, the Bulgari Octo Grande Sonnerie Perpetual Calendar has been already sold. bulgari.com
