The Casio W-202 is among the smallest and lightest wristwatches, and it offers improvements over the baseline in almost every possible way. Much more functional than the F-91W but still a very affordable timepiece.
What exactly is improved, you may ask? Well, a couple of things:
- Stopwatch goes to 24 hours
- Various alarm types
- Countdown timer (with auto-repeat, too)
- Smarter calendar
- Better backlight
- Waterproofing
Features
These are features that may require clarification and may not be found on all models:
The timer can be set with 1-second increments for up to 24 hours. You can set it to repeat automatically e.g. for interval training or to remind of medication you take more than once a day.
Stopwatch with 1/100th precision 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 to choose from: daily alarm, daily alarm for one month, alarm at a specified date, or a monthly alarm.
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.
The W-202 allows you to read the minutes and seconds in the dark, not just the hours. This is thanks to another amber LED on the right side of the display. Fixed afterglow at 2 seconds. Higher-end models of today have something they call the Super Illuminati, but this one does just fine.
You can enable a flash alert to make the backlight blink when the alarm or countdown timer goes off. This may be helpful in loud environments where tiny beeps would be difficult to hear.
