Maurice Lacroix Watch Pontos S Extreme. The Pontos S Extreme impresses from the very first glance. With its assured, self confident, masculine look and sporty image, it is available in three different colors. Its automatic three-counter chronograph mechanism follows the rhythm of the oscillations of its ML112 caliber. Propelled into the innovative and high-tech world of fine watchmaking by its technical features, the special alloy used for these Maurice Lacroix timepieces reinforces the durability and makes the watches light weight. POWERLITE. Exclusive to Maurice Lacroix, the material from which the Postos S Extreme watch case (both bezel and case middle) is made is an alloy of five elements: aluminum, magnesium, titanium, zirconium and ceramic. The crown and the push buttons are made exclusively of titanium. The robustness, durability and also the lightweight of this timepiece are irreproachable. A NATO strap adds the final touch to a watch whose strong character is matched only by its exceptional energy.
