Would you like to see how I added a Countdown Timer function to these watches? Look here... [ Ссылка ]
Here is my In Depth Review of both the W800H and W96H Casio watches. At the time of this recording, these watches were easily available for about $16 up to about $20 each. While they are super-affordable they're also packed with some nice features. The W800H is water resistant to 100 meters while the W96H is water resistant to 50 meters. The W800H uses module 3240 while the W96H uses module 3239. Each watch uses a CR2025 battery which should last an amazing 10 years. Their quartz technology means they can remain accurate to within 30 seconds per month.
In the normal timekeeping mode, each screen shows the day of the week, the time (in 12-hour or 24-hour mode), along with the year, month and date. Other modes include Alarm/Hourly Signal, Stopwatch (up to 24 hours) and Dual Time mode. Each watch has a green LED backlight which shines up from the lower-left corner of the display.
...and then there's the modification that you may-or-may-not want to try which will enable a Countdown Timer mode. It's not too easy but, then again, not too difficult. Casio doesn't tell you about that modification but YouTube does!
