According to Bulgari, NFC technology is the most secure method of data transmission to date, requiring that the two devices storing the data be in very close proximity to each other in order to connect, unlike Bluetooth and other wireless technologies. Furthermore — and if you had any doubt that the DNA of this concept timepiece is all Switzerland rather than Silicon Valley — the encrypted information in the “Bulgari Vault” is stored in a cloud that is physically situated in an underground military bunker in the Swiss Alps. If the phone is lost or stolen, the Bulgari Vault app will prompt the destruction of all data, making it inaccessible to a third party. (It’s unclear if the loss or theft of the watch would also trigger this.) The owner of the Bulgari Diagono could then subsequently restore the data with the encrypted backup activated by the watch.
The Bulgari Diagano Magnesium concept watch, like the mainstream models in the Bulgari Diagono Magnesium collection, has a 41-mm case whose middle is constructed of magnesium and a polymer called PEEK — both materials very new to watchmaking — with a ceramic bezel engraved with the double Bulgari logo and a black PVD caseback. The steel PVD crown has a black ceramic disk in its center. The PEEK material is also used for the pin buckle, which closes the watch’s vulcanized black rubber strap. We’ll be watching intently to see if this bold concept becomes a series-produced, commercial reality.
