Bulgari presents the slimmest ultra-thin self-winding timepiece on the market - the Octo Finissimo Automatic.
Featuring a total thickness of just 5.15mm, while its self-winding movement is just 2.23mm thick for a 40mm diameter, the horological instruments' extreme thinness is a complication on its own. The slenderness of the timepiece has been achieved by giving thorugh attention to each of the components' design.
Driven by an ultra-thin, entirely openworked tourbillon comprising 253 parts, featuring 13 jewels and eight ball bearings serving to reduce the overall thickness of the calibre. Beating at a frequency of 21,600 vibrations per hour, the movement delivers a 62-hour power reserve. To ensure perfect efficiency and precision, its barrel spring is equipped with a slipping spring and the tourbillon cage is fitted on a peripherally-driven ultra-thin ball-bearing mechanism. This exceptional and exclusive movement houses a barrel held by three ball bearings, an innovative feature serving to double the height of the barrel spring and thus achieve an 80% increase in power reserve, an impressive accomplishment for such a slim tourbillon model. To highlight such a movement with the panache it deserves, the case of this new Octo is made of platinum.
