Maurice Lacroix Watch Pontos S Diver PT6248-SS001-330-1. A professional diving instrument that is water resistant to 600 meters, the Pontos S Diver reinterprets the defining characteristics of the Maurice Lacroix Watches Pontos S line by adding a vintage touch to the retro design. Easy to wear and easy to read down to the smallest detail, this watch has all the features that will attract lovers of the ocean depths. A 43 mm diameter. Fashioned in stainless steel, the Pontos S Diver case is generously proportioned. Designed to professional specifications, it includes the essential requirement for a diving watch, a helium escape valve system at 9 o'clock that is completely automatic. Before returning to the surface to breathe in fresh air, professional divers first pass through a decompression chamber. There they breathe in a mixture of gases with a large proportion of helium, which can damage a watch by seeping inside it due to the pressure difference between the gas trapped in the chamber and the outside air. The Pontos S Diver's helium valve thus prevents any irreversible damage to the timepiece. The black dial is fitted with applied indexes and hands highlighted with Superluminova, enabling divers to read the details that they require in even the deepest water. The hands, also highlighted by luminescent material, are further distinguished by their color. The minutes and seconds hands are outlined in red and a date display at 6 o'clock completes the watch's features. The timepiece is driven by the self winding ML115 mechanical movement that oscillates at 4 hertz and has a 38 hour power reserve.
