The Breitling Navitimer Brillant has a self winding automatic watch movement, which is powered by the movements of the wearer and it can contain up to 42 hours of power reserve, so if it isn’t being worn or used for 42 hours, it will stay on time. It is made of a stainless steel case which is water-resistant. It has a bi-directional bezel as well as slide rule. The crystal is convex mineral, which is glare-proofed on both sides to provide the easiest readings. When purchased new, it comes with a manufacturer warranty of 2 years.
