The most distinctive specs of PRW-50 *Editorial
— 100-meter water resistance
(good for swimming but not for deep diving)
— Low temperature resistant (stable operation of the watch is guaranteed even at a temperature of -20°C)
— Radio-controlled Watch; Multi band 6 (additional way for time sync. This watch receives time calibration radio signals that keep the displayed time accurate)
— Tough Solar (CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power)
Digital compass (measures and displays direction as one of 16 points)
Thermometer (can measure and display the outside temperature in a range from -10 C to 60 C)
Barometer (measures the air pressures and displays tendencies in the weather)
Altimeter (The electronic mechanism “estimates” the altitude based on the air pressure)
Smart Access (the system for analogue movements achieves multi-functionality and easy operability simultaneously through a combination of multiple motors and an electronic crown)
Tough Movement (A CASIO-original thin analog movement made possible by hybrid mounting protects against damage and enables auto home position correction that helps keep you on time all the time)
STN LCD for easy reading
Full auto double LED light (Neon Illuminator for the face, LED light for the LCD

This new model with a lightweight, highly wear resistant Field Composite Band, is the latest addition to the PRW-50 Series from PRO TREK, the outdoor watch for serious outdoor adventurers.
The Field Composite Band combines urethane and fine resin with metal inserts for the ultimate in durability. The buckle uses lightweight titanium alloy, and a slide adjust mechanism with double lock buckle enables fine length adjustment. Durable and lightweight, the band minimizes the load on the wrist during long climbs.
The bezel, back cover, and buckle are all done to an ion plated (IP) finish.
A high-transparency and scratch resistant sapphire crystal provides the readability and toughness demanded for outdoor wear.
The powerful Tough Solar power system of this watch provides a stable supply of power for MULTIBAND 6 that automatically adjusts time settings based on reception of one of six time calibration signals around the globe, and for Triple Sensor Version 3 capabilities for measuring your bearing, barometric pressure, temperature, and altitude. This means you get uninterrupted operation both for daily and outdoor activities.
This new model is designed to deliver a comfortable fit, without sacrificing any PRO TREK function.
