Ultra sound shows (specifications g-shock load requires), mild, not too big and design that could almost be described as restrained against other casio range. The basic options can be found there for this type of watch (countdown, the time display on other time zones, alarm, etc.). Its uniqueness is probably his time with recording tricks. To make it simple, it has a stopwatch that can record 100 lap times. For example, I'm using it especially for swimming to record a total time but also all segments and therefore see the evolution between the beginning and end of a session. Regarding more or less useless gadgets but fun features include automatic lighting when you angle the watch to watch (it is obviously necessary to enable this feature) and the counting of days of the year, super useful when asks how many days in the street have passed since January and how much is left before the next Christmas Eve. Essential for maniacs of time passing.
