The Casio G-Shock Rangeman GW-9400-1DR represents the pinnacle of rugged outdoor functionality in digital horology. Engineered for extreme environments, this legendary timepiece combines Tough Solar power technology with Multi Band 6 atomic timekeeping, ensuring perpetual accuracy across six radio signals worldwide. The Triple Sensor Version 3 module integrates digital compass, barometric pressure/altimeter, and thermometer functions into a shock-resistant resin case designed to withstand the harshest conditions.
Built for serious adventurers and tactical professionals, the Rangeman features a robust 53.5mm case with 200-metre water resistance and mud-resistant construction. The negative LCD display provides exceptional contrast in varied lighting, whilst the signature red accents on the dual-layer bezel add visual distinction. Tough Solar charging technology converts any light source into power, eliminating battery changes for the life of the watch. At Cassims & Co., we are proud to offer this iconic model from our comprehensive collection of CASIO watches.
The Rangeman's Triple Sensor capabilities deliver mission-critical environmental data at the press of a button. The digital compass provides bearing information with 20-second continuous measurement, whilst the barometer tracks atmospheric pressure trends to predict weather changes. The altimeter records altitude data in 5-metre increments, and the thermometer monitors ambient temperature from -10°C to 60°C. These advanced functions are complemented by sunrise/sunset data display, world time for 48 cities, five daily alarms, stopwatch, and countdown timer.
As an authorised Casio retailer, we guarantee full manufacturer warranty coverage and expert support throughout your ownership experience. Our skilled team at our Mall of the South boutique can demonstrate the Rangeman's advanced functions in person, and our comprehensive watch servicing and repairs facility ensures your G-Shock receives proper care for years to come. Experience the ultimate survival watch that has earned legendary status among outdoor professionals and collectors worldwide.

FAQ
Q: How does the Tough Solar power system work?
A: The Rangeman's Tough Solar technology converts any light source—natural or artificial—into electrical energy stored in a rechargeable battery. Once fully charged via exposure to light, the watch operates for approximately 7 months in complete darkness with all functions active, or up to 23 months in power-saving mode. This eliminates the need for battery replacements throughout the watch's operational life.
Q: What is Multi Band 6 atomic timekeeping?
A: Multi Band 6 automatically receives time calibration signals from six transmission stations worldwide (Japan ×2, USA, UK, Germany, China). The watch synchronises automatically up to six times daily, ensuring accuracy to atomic clock standards. Even without signal reception, the quartz module maintains accuracy to ±15 seconds per month.
Q: How accurate is the Triple Sensor system?
A: The Version 3 Triple Sensor provides directional accuracy within ±5° for the compass, altitude measurements in 5-metre increments from -700m to 10,000m, and temperature readings accurate to ±2°C. The barometric pressure sensor displays trends to help predict weather changes, making this an essential tool for outdoor navigation and environmental monitoring.
Q: Is this watch suitable for diving?
A: With 200-metre water resistance, the Rangeman is suitable for recreational diving, snorkelling, and all water sports. However, it is not a dedicated dive computer—the altimeter/barometer functions should not be used underwater. The mud-resistant construction also protects against sediment ingress during extreme outdoor activities.
Q: Can I replace the battery myself?
A: The Rangeman uses a rechargeable battery charged by solar power and should never require replacement under normal use. If service is needed after years of operation, battery replacement must be performed by an authorised Casio service centre to maintain water resistance and warranty coverage. Our Cassims & Co. service team can facilitate all manufacturer-approved maintenance.
Q: What does the sunrise/sunset data function show?
A: After setting your location, the Rangeman calculates and displays precise sunrise and sunset times for your geographical position on any given date. This function is invaluable for outdoor planning, photography, and tactical operations requiring knowledge of daylight availability.
Q: How do I calibrate the compass?
A: The digital compass should be calibrated when first used, after battery replacement, or if exposed to strong magnetic fields. Calibration involves performing two figure-eight motions with the watch, a simple 20-second procedure detailed in the manual. Bi-directional calibration ensures accuracy, and the compass stores bearing memory for easy reference.
Warranty
- This watch is covered by a 1-year international Casio manufacturer warranty from the date of purchase
- The warranty is valid only when purchased from an authorised Casio retailer such as Cassims & Co.
- Warranty coverage includes manufacturing defects in materials and workmanship under normal use conditions
- The warranty covers the movement, case, hands, dial, and original bracelet or strap against manufacturing faults
- The Tough Solar rechargeable battery is covered under the manufacturer warranty for defects
- Exclusions: normal wear and tear, scratches, cosmetic damage to case or crystal, damage from accidents or misuse, water damage resulting from improper use or failure to observe water resistance limitations, damage from unauthorised repairs or modifications
- The warranty does not cover battery depletion due to insufficient light exposure (ensure regular solar charging)
- Sensor calibration adjustments and routine maintenance are not covered as warranty services
- Water resistance is not a permanent condition—gaskets naturally degrade over time and are not covered beyond the initial warranty period
- To claim warranty service, present your original proof of purchase from Cassims & Co. to our authorised service centre
- Casio reserves the right to repair or replace the watch with an equivalent model at their discretion
- Warranty service does not extend the original warranty period
Care Guide
- Rinse the watch with fresh water after exposure to saltwater, chlorine, or mud to prevent residue buildup around buttons and seals
- Avoid operating buttons whilst underwater or when the watch is wet, as this may compromise water resistance
- Expose the watch to bright light regularly to maintain Tough Solar charge—direct sunlight is most effective for rapid charging
- Store in a well-lit location rather than enclosed drawers to ensure continuous solar charging when not worn
- Clean the resin case and strap with mild soap and a soft brush, avoiding harsh chemicals or solvents that may damage the material
- Do not expose to extreme temperatures above 60°C, as this may affect LCD performance and resin integrity
- Avoid direct contact with magnetic sources stronger than typical household appliances, as this may temporarily affect compass accuracy
- If the power-saving function activates (blank display), expose the watch to bright light—the display will resume when sufficient charge is restored
- For altitude and barometric readings, allow the watch to acclimate to ambient temperature for accurate measurements
- Have water resistance tested every two years if the watch is regularly used for aquatic activities
- Avoid impacts to the sensor button (6 o'clock position) to maintain Triple Sensor accuracy
- Wipe the case back and strap regularly to prevent skin irritation from accumulated perspiration or debris
