Bulgari Diagono Professional Terra Watches

"Diagono Professional is the line dedicated to those seeking painstaking design and extreme practicality in a sport watch. Characterized by an assertive yet understated appeal, the Bulgari Diagono Professional Tachymetric Chronograph allows one to measure elapsed time and average speed.  Certified by COSC (Contrôle Officiel Suisse des Chronomètres), these chronometers constitute a collection of sport watches combining high reliability with extreme precision.  Essential for ground sports and ideal for timely-living men, the Diagono Professional Tachymetric Chronograph features three counters on the dial, which enable short, intermediate and total times to be calculated, while the tachymetric bezel indicates the average speed needed to cover a unit of measurement of space (km, miles, etc.).  The Bulgari Diagono Professional Tachymetric Chronograph is available in a 40mm size in steel, two-tone, yellow gold, white gold, and platinum with leather strap or metal bracelet.  It is equipped with a COSC certified self-winding mechanical movement, and it is water resistant up to a depth of 100 meters." - Bulgari
