Whether you’re ascending a new peak or watching for weather changes, these sensors are designed for precision and reliability, helping you stay safe and informed during your adventures.

Tough Solar Charging for Seamless Power
Say goodbye to battery anxiety. With Casio’s Tough Solar technology, the PRG-30 charges under sunlight or fluorescent light and stores energy efficiently. On a full charge, the watch can operate for up to 11 months without exposure to light—perfect for long treks and remote camping trips where power sources are scarce.

Unlike bulkier outdoor models, the PRG-30 is designed with a compact form factor that comfortably fits a variety of wrist sizes. Weighing approximately 64g and measuring just 45.2mm in diameter, this watch won’t weigh you down—whether you’re trail running, climbing, or navigating busy urban streets.

High-Contrast MIP Display with LED Backlight
The Memory-in-Pixel (MIP) LCD provides clear readability in various lighting conditions. Its high contrast and sharp text ensure you get the information you need at a glance. Plus, with a high-brightness LED backlight, the display stays legible even in pitch darkness—great for early hikes or overnight adventures.

Sporty Design in Blue-Gray Colorway
The PRG-30’s blue-gray tones offer a cool, subdued aesthetic that blends performance with style. It pairs well with activewear, hiking gear, or everyday outfits. The button layout and robust bezel give it a rugged, ready-for-anything personality, making it a solid match for both function and fashion.

Functions That Power Your Adventures

Digital Compass
Navigate with confidence using the built-in compass. The PRG-30 allows you to determine magnetic north and track direction on the go, ideal for orientation hikes, bushcraft excursions, or general navigation in unfamiliar areas.

Altimeter
Track your climb or descent with the altimeter function, capable of measuring from -700 to 10,000 meters. It’s great for mountaineering, hiking high passes, or monitoring elevation during trail runs.

Barometer
Stay weather-aware with barometric pressure readings that help you anticipate sudden changes in weather—critical for safety when venturing into the wilderness.

Thermometer
Know the ambient temperature wherever you are. From frozen peaks to sunny valleys, the built-in thermometer gives you accurate readings in Celsius or Fahrenheit.

World Time & Dual Time
With world time for 31 time zones (48 cities + UTC), you can keep tabs on multiple regions—a handy tool for international travelers or coordinating across time zones. Set a second city for quick dual time display.

5 Daily Alarms & Hourly Time Signal
Stay on top of your schedule with five independent daily alarms. Whether you’re setting reminders for hydration, meeting times, or gear checks, these alarms help keep your day on track.

Stopwatch and Countdown Timer
Perfect for interval training, cooking on the campsite, or tracking race splits, the PRG-30 includes a 1/100-second stopwatch and a countdown timer ranging from 1 minute to 24 hours.

Battery Level Indicator & Power Saving Mode
Monitor your power levels with the battery indicator, and extend runtime with the auto power-saving feature that dims the display when the watch is idle in the dark. Efficiency meets endurance.

How to Use Your Casio PRG-30 Protrek

Sensor Calibration
While sensors are factory-calibrated, periodic manual calibration ensures optimal accuracy. Use flat, stable surfaces and reference altitudes or compasses for best results.

Accessing Sensor Modes
Quickly toggle between compass, altimeter, and barometer modes using the designated button. Hold for a few seconds to enter the respective sensor mode; readings are refreshed with every press.

Solar Charging Tips
Expose the watch to natural sunlight regularly to keep it optimally charged. Although indoor lighting helps maintain battery levels, outdoor exposure—particularly in bright conditions—is most effective.

Activating the LED Backlight
For nighttime visibility, press the light button on the side to activate the LED. The auto light feature can be toggled on/off by holding down the button, automatically activating illumination when you tilt your wrist.

Adjusting World Time
Hold the lower left button to access world time mode. Scroll through city codes using the upper and lower right buttons, and press to confirm selection.
