About the Octo Finissimo family
The Octo Finissimo is the series with which Bulgari set a run of records for thinness. It began in 2014 with a very thin tourbillon, followed by a minute repeater, and in 2017 by an automatic with a micro-rotor that made the line widely known. The octagonal case and integrated bracelet, often in titanium or steel with a fine sandblasted finish, became the signature look.
The catalog includes many references, among them hand-wound models, skeleton versions, chronographs, tourbillons and limited editions in gold, ceramic and carbon. Because the case is so thin, check it and the bracelet for bends, dents and wear, confirm the caliber against the reference, and expect buyers to ask for the full set.
