EasyDiver. Roger Dubuis. "The EasyDiver collection is defined by its potent, athletic looks and its technical acumen. An extraordinary haute timepiece built to withstand demanding outdoor conditions, EasyDiver is one of the first in horological history to incorporate a flying tourbillon into a sports watch. Each casing can resist pressure of up around 300 meters, and has a specially-designed movement - a miniature engine tuned to the most precise engineering standards and mechanical tests.
