Following the early principles of the Oyster Perpetual family, the 2015 additions focus solely on reliable and accurate time telling, with the high-precision movement nested safely inside the renowned Oyster case. The 39mm case, with middle case made of a solid block of 904L stainless steel, features domed bezel and scratch-resistant sapphire-crystal. Its 100m water resistance is accomplished with the fluted screw-down case back and the Twinlock double waterproof system for the screw-down crown. Inside, the self-winding Perpetual 3132 caliber certified by COSC features the blue Parachrom hairspring and Paraflex shock absorbers, as well as bidirectional self winding via Perpetual rotor. The elegant blue dial with neat hour markers features hours, minutes and seconds indication by centre hands. The watch is worn on the wrist with the 904L stainless steel Oyster bracelet with flat three-piece links and the Oysterclasp.
