The PRO TREK PRW-B1000 is a genuine outdoor watch designed for use in the great outdoors. Its square stainless steel bezel, inspired by El Capitan in Yosemite—a mecca for outdoor enthusiasts—and the small hand at the 9 o’clock position, modeled after the pitons once used by rock climbers, express a sense of respect for nature and a spirit of adventure. The Tough Solar system generates power even from weak light sources such as fluorescent lamps, ensuring stable operation of functions like radio wave reception and the light. You can use it with confidence, even during long treks or camping trips, without worrying about the battery running out. The Multi-Band 6 feature, which receives standard radio signals from six stations worldwide (two in Japan, plus China, North America, the UK, and Germany), combined with a two-way automatic time correction function via Bluetooth connection, is a unique feature of the PRO TREK series. It supports your outdoor activities with consistently accurate time. Equipped with a triple sensor (compass, barometric pressure, and temperature), it accurately measures direction, barometric pressure, altitude, and temperature. The large button design ensures reliable operation even when wearing gloves. When paired with a smartphone via Bluetooth, you can use automatic altitude correction and the location indicator to check the direction of your destination. The route log function also lets you record your activities. Alarm and timer settings can be easily managed via the app. The high-brightness, fully automatic dual LED light illuminates the analog dial and digital display simply by tilting your wrist. This allows you to check the time even in the dark or when one hand is occupied. The case is made of flame-retardant biomass plastic, and the band uses lightweight, high-strength cellulose nanofiber (CNF). Made from eco-friendly, recyclable materials, it aligns with the values of nature lovers. With 10 atm water resistance, the PRO TREK PRW-B1000 is a model packed with high functionality and practicality, making it a reliable companion for all outdoor activities, from camping to serious mountaineering.

The time zone difference is set based on the selected city. Sensor Function Details * The altimeter is a relative altimeter that converts changes in atmospheric pressure into altitude. When atmospheric pressure changes due to weather conditions, the measured altitude will also change. * When measuring the outside temperature, remove the watch from your wrist to prevent it from being affected by body heat, sweat (water droplets), or direct sunlight.
