The Octo Finissimo ("very thin") lives up to its name with an impressively thin movement. Even with a tourbillon, the 1.95-mm thick movement is thinner than a Swiss five franc coin. Bulgari is one of the few manufacturers that develop and manufacture their movements completely independently. Industry experts consider these so-called manufacture movements as a sign of exclusivity. The Finissimo's case is available in rose gold or platinum, with its surfaces partly polished and partly satin-finished.
The Magnesium, introduced as a part of the Diagono collection in 2015, is a particularly innovative watch. It has a ceramic bezel but is otherwise made of unique materials. Bulgari uses magnesium for the case because it is particularly lightweight and durable, even more so than titanium. They also utilize a special heat-resistant polymer, PEEK (polyether ether ketone), which is used in the aviation and aerospace industries. Watches from this series are sporty, robust, and waterproof to 100 m. The diving watch Diagono Scuba is even more impressive: It is waterproof up to 300 m. The Italian manufacturer Panerai offers diving watches that are similar to the Scuba. The Diagono collection is made up of three-hand watches with central second registers and chronographs. Like the Octo, Bulgari also offers a version of the Velocissimo with the caliber BVL 328.
