The simply designed Casio G-Shock Classic digital watch for men offers shock resistance that's great for your most vigorous sporting activities. The durable rectangular black watch case measures 45mm wide (1.77 inches), and it's matched to a comfortable black resin sports strap. It includes a stopwatch function that can measure events down to 1/100 of a second for the first 60 minutes (and down to 1 second from 60 minutes to 24 hours), and it offers elapsed and split time modes, and 1st-2nd place times. It also has a countdown timer with a 24-hour range. Other timekeeping features include a multi-function alarm, hourly time signal (which can be turned off), and 12/24-hour formats. This timepiece also features an Auto Calendar (pre-programmed until the year 2039), ±15-second accuracy per month, Afterglow backlighting, and water resistance to 200 meters (660 feet)--which will stand up to the rigors of recreational scuba diving.
