Casio Pro-trek PRW-3000B-1DR , Digital Men's Watch, Black
An essential instrument for those who love the outdoors. This watch has a high energy efficiency so that you don’t run out of charge under very dim light conditions. Highly accurate, it’s the wonder of the miniaturized sensors, which also bring maximum precision to altitude, barometric pressure, and direction readings. To stay prepared for nasty weather, the Barometric Pressure Tendency Alarm is a great feature.
