Damasko Watch DSub50 Rubber Sport Deployment Buckle. The Damasko Watches DSub50 with a casing made of austenitic submarine steel scores with its high strength and simultaneous ductility. The steel is corrosion resistant and completely anti-magnetic, even when continuously immersed in seawater. The black DAMEST coating draws additional attention to the striking stainless steel casing of this divers watch. Combined with the black dial, this timepiece completes a dark neoprene suit to perfection, so that only the luminescent indices and the cambered sapphire crystal with special anti reflective coating on both sides remain in focus and ensure easy readability, even in adverse visibility conditions.
