Review on ⌚ CASIO AE-1500WHX-1A Quartz Watch - Alarm Clock, Chronograph, Stopwatch, Countdown Timer - Display Backlight - Shockproof and Waterproof by Aneta Postek ᠌

Great option for this price. The countdown timer does not seem to be configurable, only 60 minutes. You can swim and dive. I think it will definitely withstand 30 meters under water. Practice has shown that such watches from Casio last for a very long time - just change the battery. Coloring begins to peel and fade after 3-5 years, depending on use. I like it, they don't look bomzhovski, unlike skmei and so on.
