This piece of rare game goes for an awful lot of coin. It has an interesting history, as well, starting out as the Gerald Genta Arena Metasonic Sonnerie watch. When Bulgari engulfed the Gerald Genta brand (head nod to Genta who just passed away), they kept this piece and made a few style changes to the dial and case (very minor), the movement remained the same with the price still hovering around $1,000,000. Bulgari also changed the name of the watch from Metasonic to Magsonic and dropped the Arena part of the name.
Does Magsonic mean anything more than Metasonic? Magsonic is a new alloy that Gerald Genta created for optimal sound passage. Most of the case is actually titanium, though it is also offered in 18k rose gold. The Magsonic part of the watch is the black-looking part sandwiched between the bezel and caseback. The titanium (versus gold case) is probably a better idea if you are interested in the main feature set of this timepiece – the complex sonnerie complications – because gold will absorb more sound. It also has a tourbillon (seen from the dial), power reserve indicators (there are two as one is for the time and another is for chiming functions), and well, yes, the time.
