Bvlgari Diagono Pro

The Diagono Professional series is based on three different worlds, presented by three of nature's basic elements: air, water and earth: aira, aqua and terra. Each sports a rigorous design and high-tech features.  The Diagono Professional series is not a light-weight watch. These are super-charged timepieces that have serious physical endurance and are ready for rough and tough play. The series is named after the three forces of nature: air, water and earth.
