This watch is based on a German Military Diver watch. And, you should have no trouble reading the time with the large numbers and markers. When charged with light, the whole dial glows a bright green color in the dark. The smaller red hand is a 24 hour GMT indicator which can be set to a second time if you wish. An inner scale shows the time in 24 hours. The movement is a Swiss-Ronda Cal.515.24H quartz type. There is a special screwed crown protecting system (with a screwed cover) at the 10:00 position. With a domed hardened mineral crystal. Case: Solid stainless steel, brushed, 52mm diameter, 17mm thick. Band: 24mm, high quality leather strap. Water Resistant: 50ATM (1640 feet) Warranty: 2 Years
