Review on Wrist watch CASIO Pro Trek PRW-30-1A by Momchil Ivanov ᠌

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. Different pros: Easy to wear, almost impossible to discharge, small size, multifunctionality Got 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
