High quality A.Lange & Sohne replica. This stainless steel case is Swiss made and the movement is a Japanese Automatic sweep movement. (It is powered from the movements of the wearer) Its black face is protected by a mineral crystal glass, which is harder than glass and softer than the sapphire crystals, but still exceptable. Over the dial lay 3 fully unctional sub-dials, the watch also including month and year windows. It comes with a trusty leather band and a skeleton back with all the markings to make this baby look like the real deal. The markers and the hands are exact to the real watch, making this one a good replica.The weight is to exact original. Water resistant.
