The Octo Ultranero is presented right from its introduction with the world’s thinnest mechanical tourbillon movement, the Bulgari BVL 268 Finissimo calibre, which at the time of its launch in 2014 set a record that has remained unbroken ever since. The mechanical heart of the watch is revealed in its carriage visible at 6 o’clock on the black dial, accentuated by the pink gold elements in the finishing of the flying tourbillon which measures a mere 1.95 mm thick.
All interpretations of the Octo Ultranero watch are equipped with mechanical calibres from Manufacture Bulgari, where they are assembled and finished by hand. Depending on his wishes, inspirations and usage, the connoisseur can choose a version with a 41mm diameter powered by the Solotempo BVL 193 calibre. Dedicated to the measurement and display of time, this twin-barrel movement has a 50-hour power reserve and focuses on ensuring the precision of the hours, minutes, seconds, and date indications. For an even sportier touch, others may opt for the Octo Velocissimo Chronograph powered by Calibre BVL 328, capable of capturing the flow of time to the nearest tenth of a second.
