This model has no automation and allows you to set a secondary time down to the minutes.

Casio heard we like timers, so they put a timer in their timer. The range is up to 24 hours with 1-second increments. You can make the countdown repeat automatically, and you can set a start time within 24 hours. These are not the most common features.

Stopwatch with 1/100th precision up to 24 hours. Displays elapsed time and can be toggled for split times and 1st and 2nd places.

The split time in Casio watches means freezing the elapsed time on the screen while the stopwatch keeps running in the background. E.G. if you run 1:36 laps with a steady pace, your first split time will be 1:36, the second one 3:12, then 4:48, and so on.

You can set hourly time signals on or off, and the watch has a multitude of alarms: daily alarm, daily alarm for one month, alarm at a specified date, and a monthly alarm. You can save up to five alarms and one of them can be set for snoozing.

You don't have to check the date setting of this watch each month: leap years, Februaries, and Biblical events are covered for a very long time – automagically.

This watch has two amber-colored LEDs for viewing in the dark. The Afterglow is fixed to 1.5 seconds. Higher-end models of today have something they call the Super Illuminati but this one is just fine.
