At the Heart of Performance: Triple Sensor Version 3 Technology

The Casio PRO TREK PRW3500Y-1CR showcases CASIO's proprietary Triple Sensor Version 3 technology, a revolutionary advancement that redefines what's possible in a compact, wrist-mounted device. This innovation allows for sensors that are an astonishing 95% smaller than those found in previous models, enabling a more streamlined and comfortable watch design without compromising on functionality. Despite their miniature size, these new sensors deliver significantly improved reading accuracy and remarkable energy efficiency, ensuring precise data collection for longer periods.

This advanced sensor array provides three critical measurements:

• Precision Altimeter: For mountaineers, hikers, and trekkers, an accurate altimeter is indispensable. The PRW3500Y-1CR measures altitude from -700 to 10,000 meters (-2,300 to 32,800 feet) with a fine resolution of 1 meter (5 feet). This feature is vital for tracking your ascent and descent, understanding your current elevation, and planning your route. The watch offers manual memory measurements for up to 30 records, each including altitude, date, and time – perfect for logging key waypoints on your journey. Additionally, it provides auto log data (high/low altitudes, auto cumulative ascent and descent) and trek log data (up to 14 records of high/low altitudes, auto cumulative ascent and descent for specific treks), allowing for detailed post-hike analysis. Relative altitude readings (up to +/- 3,000 meters) and selectable measurement intervals (5 seconds or 2 minutes) provide flexibility for various activities. This altimeter is your reliable partner for elevation tracking, ensuring you always know your vertical progress.
• Digital Compass: Navigation is fundamental for any outdoor adventure. The integrated digital compass measures and displays direction as one of 16 cardinal points, covering a full 0 to 359 degrees with a precise 1-degree measuring unit. It offers 60 seconds of continuous measurement, a clear graphic direction pointer, and robust calibration features including bidirectional calibration, Northerly calibration, and magnetic declination correction. The bearing memory function allows you to store a specific bearing and easily reference it, making it an invaluable tool for orienting maps, maintaining a straight course in challenging terrain, or even setting up camp correctly. This compass provides essential directional guidance, ensuring you can confidently find your way even when visibility is limited or traditional landmarks are absent.
• Barometer for Weather Forecasting: Understanding atmospheric pressure changes is key to predicting weather shifts in the backcountry. The barometer displays a range of 260 to 1,100 hPa (7.65 to 32.45 inHg) with a unit of 1 hPa (0.05 inHg). The watch features an atmospheric pressure tendency graph, providing a visual representation of pressure changes over time. An atmospheric pressure differential graphic and an arrow indicator (atmospheric pressure change indicator) signal significant changes in pressure, which can forewarn you of impending storms or improving weather. This meteorological insight can be a lifesaver, allowing you to make informed decisions about continuing your trek, seeking shelter, or adjusting your plans based on real-time environmental data.

Unrivaled Power and Precision: Tough Solar and Multi-Band Atomic Timekeeping

The Casio PRO TREK PRW3500Y-1CR is designed for self-sufficiency, ensuring it remains operational even on extended expeditions far from power sources.

• Tough Solar Power: This cutting-edge solar charging system converts even faint light from fluorescent lamps or direct sunlight into power, eliminating the need for regular battery replacements. A highly efficient solar panel integrated into the watch face captures ambient light, charging the internal rechargeable battery. This means your watch is always ready, offering approximately 7 months of operation on a full charge without further exposure to light. The power-saving function further extends this life by automatically disabling the display when the watch is left in the dark, preserving energy for when you need it most. For those who venture off-grid, this sustainable power source is a significant advantage, ensuring your vital information is always at hand.
• Multi-Band Atomic Timekeeping: Precision timekeeping is critical, especially when coordinating plans or relying on time-sensitive navigation. The PRW3500Y-1CR automatically receives time calibration radio signals from atomic clocks in the US (WWVB), UK (MSF), Germany (DCF77), Japan (JJY40/JJY60), and China (BPC). These signals keep the displayed time exceptionally accurate, with an auto-receive function up to 6 times per day (5 times for China) and a manual receive function. This ensures that whether you're in the Rockies or the Alps, your Casio PRO TREK watch displays the exact time, providing ultimate reliability for scheduling and timing critical events. Even without signal calibration, the watch maintains an impressive accuracy of +/- 15 seconds per month.

Built for the Extremes: Durability and Resistance

The PRO TREK series is synonymous with ruggedness, and the PRW3500Y-1CR lives up to this reputation, designed to withstand the harsh conditions of any adventure.

• 200M Water Resistance: Whether you're caught in a torrential downpour, navigating a whitewater river, or engaging in surface water sports, the 200-meter water resistance ensures your watch remains fully functional. This high level of water resistance means it can handle accidental submersions, making it suitable for activities like swimming, snorkeling, and rafting, without concern for internal damage.
• Low Temperature Resistant (-10 C / 14 F): From icy mountain peaks to freezing winter trails, extreme cold can compromise electronic devices. The Casio PRO TREK PRW3500Y-1CR is built to perform flawlessly even in frigid temperatures down to -10°C (14°F). This resilience ensures that the sensors and display remain responsive and accurate, providing reliable data when you need it most in cold environments.
