One of Panerai’s most impressive developments is Carbotech, a proprietary carbon fiber and polymer compound that is 64 percent lighter than titanium and 80 percent lighter than steel. It comprises the case, bezel and locking crown bridge of the new Luminor Marina PAM01707. The new Luminor Marina PAM01707 is made with Panerai’s proprietary Carbotech. PaneraiDespite using an advanced new case material, this Luminor Marina retains the mid-century toolish charm of its steel predecessors. The Luminor Marina features a 44mm Carbotech case.
