This is the most complicated Bulgari watch ever

Italian luxury brand Bulgari, over the past one decade, has mastered the art of making jaw-droppingly slim watches, earning many world records in the process. The company’s Octo Finissimo Tourbillon Automatic, launched earlier this year, managed to create three records: thinnest tourbillon, thinnest automatic tourbillon, and world’s thinnest automatic watch. This has made the brand synonymous to ultra-thin watchmaking. However, Bulgari’s latest offering in the haute horlogerie category is a proof that the Italian company just as capable at making ultra-complicated timepieces. Called the Octo Grande Sonnerie Perpetual Calendar, it is being touted as the most complicated watch Bulgari has ever produced. The watch was unveiled in Rome in July and shown to journalists at a September event in Shanghai, and it has already been sold for an undisclosed sum, reportedly to a collector in Asia.

The Octo Grande Sonnerie Perpetual Calendar is a watchmaking masterpiece that brings together the complications of a tourbillon, minute repeater, petite and grande sonnerie, perpetual calendar, moonphases, and GMT functionality in a single timepiece. The watch comes with a 44 mm sandblasted 18-karat rose-gold case with a transparent caseback, which encloses a total of 976 parts. It is powered by the in-house automatic caliber BVL 5307 sounds the hours, quarter-hours and minutes on demand, and offers a power reserve of 48 hours for the movement and 28 hours for the striking system. It is paired with a black alligator strap with an 18-karat rose-gold sandblasted folding clasp.
