The Illuminator is a style of sports watch made by Casio. As the name implies, the Illuminator lights up so you can tell time even in the dark. The watch indicates not only time of day, but also the current date if you set it properly. The Illuminator includes alarm and stopwatch functions as well. Once it's set, you should not have to adjust the time again unless you change the battery or travel to another time zone.
