1. Altimeter. The deviations of which within one day / hike / measurement and the accuracy of measurements deserve respect, and although the instructions say that these are not reference indicators and you should not rely on them, you can safely use them on a hike or at home.
2. Compass. Comfortable enough, although graphically not large, but with a digital display of the angle to the north. The compass is many times (if not an order of magnitude) more accurate than similar counterparts installed in phones and various non-professional household gadgets, besides, it is much more convenient to use it and always with you, with good battery life.
3. Barometer. A good helper to help predict the weather. But here the "brains" of the user are already required, if you like, then a skill, that is, you have to spend time.
4. Thermometer. Measures the temperature inside the case. Since the clock is on the arm, then the practical application can only be if they are located in a measured environment, for example, in a stream.
5. Sunrise-sunset. A pleasant, informative addition to everything, the main thing is to check, and, if necessary, indicate the correct coordinates of the position on the planet.
6. Case, strap, material quality, weight. Thanks to everything, they sit on the hand and feel pleasant, not burdensome.
7. The absence of overly bright and contrasting inscriptions on the watch, which is generally not typical for G-Shock. This was noticed immediately and was an indisputable argument in the choice.
8. Buttons and controls - everything is thought out and using the modes is quite convenient and intuitive.
9. Timer and stopwatch with a large measurement range. I did not know that previous models had a timer range limited to an hour.
