Designed for durability, Casio's DW5600E-IV G-Shock watch handles whatever challenge you throw its way, from light exercise such as jogging and skating to more element-intensive athletic feats, such as swimming (it's water-resistant to 200 meters). Athletes engaged in cross training will appreciate the 1/100-second stopwatch, which measures net time, split time, and first- and second-place times. The watch also counts down in the opposite direction, with an input range of one second to 24 hours. And, of course, the watch is outfitted with most of the traditional digital watch functions, such as an hourly time signal, a daily alarm, and an electro-luminescent backlight. The DW5600E-IV accepts the CR2016 battery, with an approximate battery life of two years, and carries a one-year warranty.
