Review on CASIO G-Shock GW-9400-1E quartz watch, alarm clock, notebook, chronograph, thermometer, barometer, compass, altimeter, stopwatch, countdown timer, waterproof, shockproof, power reserve indicator, display backlight, black by Adam Koakowski ᠌

Dear climbers, this altimeter works as follows, since it is tied to a barometer, its approximate accuracy will be within a short time, i. E. several hours. For example: you set up a camp for acclimatization at an altitude of 3000m, set a height of 3000m on your watch and went to the top for training, you need to climb 200-300m and the watch will tell you this without any problems. That is, before each ascent, it is necessary to set the height on the GP es instrument so as not to give it every half hour in the cold to understand the height. It is much easier to look at the clock.
