Who knows Casio watches, know that you can leave the manual in the box. Not even three minutes then the little miracle of technology was provided.
That on the back no longer, as is in the 80s, "Made in Japan", but "Made in China" does not bother me. Many well-known manufacturers can produce high quality products in China.
About the technology: Stopwatch, Countdown, World time with possibility of daylight saving time setting, lighting (. Switchable from 1-3 sec) and alarm on board and make the clock an all-rounder.
Best for last: The battery life! I have never experienced that at a Casio clock battery has given up! Sounds strange, but rather the clock breaks down when the battery gives up! And thanks to modern technology, the clock has a battery life of 10 years - in my experience, probably five years longer if you use them normally and not sleeping on the lighting button :-) Speaking of lighting: The full-length light that was a while usual , has been replaced by a single LED at the left edge of the screen, perfectly adequate and especially energy-saving in my opinion.
All in all, a clock that withstands everything, 100 meters waterproof and at a sensationally low price!
Absolute buy recommendation!
