Built with military professionals in mind, the Casio Tactical Tough Digital DW6900MS combines durability with tactical utility. This watch is water resistant up to 200 meters and shock resistant, ensuring that it holds up in tough conditions. The watch is built with a 1/100 second stopwatch and a countdown timer, perfect for use in the field, as well as a full auto-calendar that is pre-programmed until the year 2039. Set the watch to a 12- or 24-hour format and use the multi-function alarm to stay ready for whatever your day has in store. A matte black finish creates a non-reflective profile for times when stealth is key.
