Casio Men's Sea Pathfinder Solar Atomic Watch #SPW1000-2V  Amazon.com Product Description: Made for the rugged sea-farer, this Casio Pathfinder Triple Sensor men's digital watch (model SPW1000-2V) includes a built-in digital compass, thermometer, barometer, and depth gauge. It's also solar powered and offers wireless atomic clock updates. This radio-controlled watch receives a time calibration signal transmitted from Fort Collins, Colorado, and signal reception is possible within a radius of about 2,000 miles from the Fort Collins transmitter. You can choose to automatically receive this signal four times a day, or manually update the watch to the atomic clock. And because it's solar-powered--charging in either sunlight or indoor light--you'll never have to deal with changing the battery. Light enters the watch through the sapphire crystal and dial, and hits a solar cell beneath the dial. Current is created and stored in the battery. The digital compass displays 16 directions and has a 5-set memory capacity that captures direction, month, date, and measurements time data. You can predict changing weather patterns using the PathfinderÕs barometer. It takes readings every two hours, stores them automatically, and can graphically display the barometric pressure for the past 26 hours. It also offers a depth gauge to measure and record ranges from 0 to 80 meters (0 to 263 feet). You can change from meters to feet easily. The watch uses a system-specific nitrogen loading graph. Timing functions include a 1/100-second stopwatch with a 60-minute measuring capacity with elapsed time, split time, and 1st/2nd place time modes, optional hourly signal, daily alarm, 12/24-hour format, and autocalendar (to 2039). Other features include a durable blue resin case and strap, scratch-resistant mineral crystal, AfterGlow LED electro-luminescent backlight, and water resistance to 100 meters (330 feet).
