Stopwatch with 1/100th precision to 60 minutes only (most others measure up to 24 hours at least). 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 one daily alarm.

Most modern watches have a fully automatic calendar for decades to come. This one is smart enough to know that February has 28 days. As all months do, when you think about it, but February has just 28 days. Except on leap years.

Check the date sometime.

A single amber LED lights up the left side of the display. Higher-end models of today have something they call the Super Illuminati. You can make do with this one, it's a bit better than the old green ones.
