This [Diagono Magnesium] is a high-tech material molded with the latest cutting-edge technology and sent back to the world.

The middle case that surrounds the movement is made of magnesium, which is lighter and stronger than titanium or aluminum.
The side brackets of the middle case are made of shock-resistant PEEK (polyetheretherkelton), and the bezel is made of scratch-resistant ceramic.

The ceramic bezel is engraved with the “BVLGARI” double logo, which can be said to be the biggest feature of Bvlgari watches.
