Bvlgari was founded in Rome in 1884 by the Greek silversmith Sotirios Voulgaris. Known first for its jewellery, with bold colour combinations of gemstones and a strong Roman architectural influence, the house also builds its own watch movements in Switzerland. Its Octo Finissimo line has set several records for ultra-thin mechanical watches.
The Serpenti, a snake motif used since the 1940s, appears in watches and jewellery, including the Spiga version with a ceramic and gold bracelet. The Diagono Professional, with its sports chronographs, GMT and Acqua diver models, comes from the brand's earlier sports range. The Octo, Bvlgari Bvlgari and Lvcea watches and the B.zero1 jewellery complete the line-up.
