Casio Protrek Solar Power Watch PRG-50T

The Casio ProTrek Watch PRG-50T model features three sensors and a Tough Solar power system that eliminates the need for battery replacement.

There is also a cumulative ascent altimeter demanded by skilled mountain climbers. In addition to calculating the total ascent, the Casio ProTrek Solar Power Watch PRG-50T also displays the relative altitude from a selected point.

A full auto electro-luminescent backlight automatically illuminates the display whenever the watch is angled towards the face while lighting is dim. Following a full charge, the Casio PRG-50T can continue to run for approximately 5 months without charging. If the watch is left in the dark without being operated, power saving feature causes it to enter a sleep mode, which keeps it running for about 23 months. The battery recharges and full operation is restored by exposing the watch to light again.
