Casio Pro Trek PRW-61-3ER Outdoor Watch

The Casio Pro Trek series is a specialized line of multifunctional watches designed specifically for outdoor enthusiasts, hikers, and trekkers. Originally launched by the Japanese electronics giant Casio Computer Co., Ltd., the brand has become a staple for adventurers due to its Triple Sensor technology, which provides compass, altimeter/barometer, and thermometer readings. The Pro Trek line represents Casio's commitment to high-performance utility gear alongside its famous G-Shock series.

Manufacturing for the Pro Trek line primarily takes place in Casio's high-tech facilities in Thailand, although certain premium models or components may still be produced in Japan. The PRW-61 series is notable for being one of the first Casio models to use biomass plastics in the case and band, reflecting a shift toward environmental sustainability. As of 2024 and beyond, Casio remains independently owned and operated, maintaining its headquarters in Tokyo, Japan, and continuing to innovate in the rugged wearable technology sector.
