Perfect for rugged adventurers and weekend warriors, the solar-powered Casio Pathfinder men's titanium sport watch is loaded with a digital compass and altimeter/barometer/thermometer--perfect for both mountain trekking and cave spelunking. The durable round watch case (measuring 52mm/2.04 inches wide) and bracelet are made of titanium, which is nearly 50 percent lighter than steel, but 30 percent stronger. It's also particularly resistant to salt water corrosion, as well as hypo-allergenic--perfect for those with metal allergies. This watch also features a ±15-second accuracy per month, Afterglow backlighting, and water resistance to 100 meters (330 feet)--offering protection from accidental splashes as well suitable for swimming, snorkeling, and light recreational diving. This solar-powered watch has a battery life of up to 6 months on a full charge (without further exposure to light).
