Inspired by the world of aviation, Richard Mille timepieces are known for their exceedingly complex fabrications while remaining highly functional, and faithful to the codes and requirements of Haute Horlogerie. Mille’s new RM 039 Aviation E6-B Watch is an ultra-modern interpretation of the E6-B flight computer — a rudimentary flight instrument invented in the 1930s that was used to aid in calculating fuel burn, wind correction, ground speed, time en route, estimated time of arrival and other information critical to pilots. This data can all be calculated by the RM 039, which incorporates the same slide rule into the bidirectional rotating bezel. The RM 039′s exclusive tourbillon movement houses 740 parts, 58 jewels and a 70-hour power reserve housed in a titanium case. The dial’s unique, but somewhat dramatic aesthetic is due in part to the faithful reproduction of the visual codes used in the aviation industry. And lastly, of course this watch also tells the time — local, or UTC. Understandably, production of the RM 039 Aviation E6-B will be exceptionally limited — only 30 pieces are expected to be made.
