Wenger watches are designed to meet the most rigorous military requirements. The specifications would impress even the boldest watchmaker. They will withstand use in extreme cold and humidity; withstand impacts, magnetism, and sudden changes in altitude. During the Swiss Commando Raid, which brings together military teams from fifteen countries, Wenger watches are subjected to the worst that can be inflicted on a timepiece, and not on laboratory test benches, but for real. You can wear them without fear during your sporting or leisure activities. The GST is an elegant yet granite like watch with quartz movement and water resistance to 100 meters (330 ft). The case diameter is an impressive 43 mm, enabling clear and precise readings at a glance. It is lunminous for night time visibility, has a chronograph function and unidirectional rotating bezel.
