The Electric ED01 Nato Watch features a retro look that's thin, light and tough enough to give you all the info you need in any situation. The movement is the brain of the watch. It is the mechanical entity that keeps accurate time. A movement should be evaluated by the functions it provides, how it provides those functions, and the quality of manufacturing. Electric utilizes the most accurate and most durable Japanese and Swiss analog movements on the market. In digital watches the brain is called a module and can be programmed for a wide range of functions.
