The Bell & Ross Professional watch collection emcompasses a diverse range of timepieces in four distinct families--the Space 3, the Grand Prix, the HydroMax, the Marine Type and the Deminieur Type. Intended for the most rigorous applications in aeronautics, racing, diving, and bomb disposal, respectively, these exceptional timekeeping instruments epitomize the essential parameters that Bell & Ross has pursued from its inception. Animated by either selfwinding or quartz movements, depending upon the suitability for each watch's mission, the Bell & Ross Professional watch collection employs innovative design elements that foster functionality and performance that are unaffected by extremes.
