Ideal for any athlete, Casio’s Digital Sport watch features built-in referee timers that track total event time and nine countdown timers for interval training. A digital time display over a gray dial allows time telling at a glance and it also has a day, date, and month calendar to keep you on track. Powered by digital-quartz movement, the 40.6-millimeter case is water resistant to a depth of 330 feet and is protected by a mineral dial window.
