The Casio Pro Trek PRG-600-1 is a safari-styled outdoor adventure watch featuring a durable stainless steel bezel with silver finish and comfortable black silicone Dura Soft band. This analog-digital watch combines rugged construction with sophisticated sensor technology designed for outdoor enthusiasts.

The watch is equipped with Triple Sensor Version 3 technology that measures altitude up to 10,000 meters (32,800 feet), atmospheric pressure from 260 to 1,100 hPa, directional bearing with 16-point compass, and temperature from -10 to 60°C (14 to 140°F). The altimeter includes manual memory for up to 30 records and auto log data for high/low altitudes and cumulative ascent/descent. The barometer features a pressure tendency graph and alert alarm for significant atmospheric changes. Direct measurement buttons enable one-touch activation of any sensor function.

Powered by Tough Solar technology, the rechargeable battery provides approximately 7 months of normal operation or 25 months in power-saving mode after full charge. The watch is water-resistant to 100 meters and features low-temperature resistance down to -10°C (14°F). The STN LCD display ensures excellent readability, while large Arabic numeral hour markers at 12, 3, and 9 positions with luminous Neobrite coating and wide analog hands provide easy time reading in any conditions. Double LED lighting illuminates both the analog face and digital display with selectable duration and afterglow.
