Review on Wristwatch CASIO Pro Trek PRW-30-1A Quartz, built-in memory, alarm clock, chronograph, thermometer, barometer, compass, altimeter, stopwatch, countdown timer, frost resistance, waterproof, power reserve indicator, backlight display, black by Kiril Andreev ᠌

I went with a watch to Elbrus, all the conditions were met. During the ascent, we found that the height indicator is about 5% behind the real value. Has some pros: Easy to wear, almost impossible to discharge, small size, multifunctionality Has cons: Altrometer, barometer and compass work approximately The pressure is measured "unlikely", it's hard to get used to Six months later, they are ahead of the current time by 10 seconds, it is necessary to adjust
