According to our smartwatch expert
The Casio G-Shock Classic GW-7900B-1ER is a men's watch that works on light energy. You read the time, 24 hour indication and date on it. You also use the watch as a stopwatch or alarm and also look at the moon phases and the tides. Thanks to the automatic calibration, the position of the hands is checked and corrected every hour. So you always know exactly what time it is, even if the hands are staggered by magnetism or shock. Thanks to the watch is 20 bar waterproof, so you wear it while swimming.

After a long search, I finally opted for this watch because of the good water resistance, handy functions and that it charges via the sun. Unlike other G-Shocks, this watch is not extremely large, so it fits well on my narrow wrists.
The only drawback I've encountered so far are the four "screws" on top. After wearing the watch for a week, I noticed that one of the screws was loose. Trying to retighten it didn't work. After a short search on the internet, this turned out to be due to the fact that they are not real screws but a kind of caps. I think that is a major setback for a watch of this price and quality and I have therefore considered returning the watch. In the end I decided to keep the watch because the "screws" just move back and forth and don't look like they're going to fall out any moment.
Apart from that one flaw, I am very satisfied with the watch and its functions that work as designed.
