The bright illuminating feature of the Casio Men"s Illuminator Sport Watch make it a great accessory for nighttime runs and other sports. Constructed with a strong resin case, the timepiece includes a stationary blue bezel and a black resin band with an adjustable buckle clasp for the perfect fit. A durable mineral window shields the digital-gray dial face, which displays the time, along with the day and date. Easy-to-use light, mode, and start/stop buttons along the bezel make this watch great intuitive for athletes. Powered by quartz movement, this watch is water resistant to 165 feet.
