This state-of-the-art collection is waterproof and functions extremely well in the punishing saltwater environment. The low glare, satin black case of each precision instrument is constructed of solid aluminum that is color anodized and sealed so that the finish will not peel, bubble, or tarnish. The glass crystal sits in a double O-ring seat for vibration, impact, and thermal expansion protection. The anodized aluminum dial is laser engraved. The durable moveable markers are made of U.V. stabilized polycarbonate outside the crystal for marking time or pressure. All fasteners are stainless steel
