Just bought a nice Casio Gshock GA2100 model 5611, no Dutch manual is included at all. I think it's a bad thing. Can someone help me with a Dutch manual or a suggestion where I can find that manual on Google?

What is a quartz movement? Verified

Watches and clocks with a quartz movement are driven by a battery. This sends an electric current through quartz crystals that will vibrate. These vibrations are passed on to the movement. Because the vibrations have a fixed frequency, watches and clocks with a quartz movement are extremely precise.

There is moisture on the inside of the glass of my Casio watch, what should I do? Verified

Casio states that if the moisture appeared after an extreme change in temperature and disappears relatively quickly afterwards, there is probably nothing wrong. If the moisture does not disappear, you should have your watch repaired as soon as possible.
