The Casio G-Shock is a series of watches designed for durability. There are dozens of G-Shock watches; they are identified by their module number, a four-digit number located on the back of the watch. Most G-Shock watches allow you to set a daily alarm. Although the procedure to set the alarm varies between G-Shock watch models, it isn't difficult, and it only takes a couple of minutes.
