G-Shock Rangeman GW-9400

Product Overview

The G-Shock Rangeman GW-9400 is a high-performance tactical watch engineered for outdoor enthusiasts, adventurers, and professionals who demand precision and durability in extreme conditions. Built by Casio, this rugged timepiece combines advanced environmental sensors with military-grade toughness to deliver reliable performance in the harshest environments. Whether you’re navigating mountain terrain, monitoring weather changes, or tracking altitude during expeditions, the Rangeman provides essential data at a glance. Its atomic timekeeping ensures you’re always synchronized with the most accurate global time signals, making it ideal for travelers and field operatives alike.

Key Features

• Atomic Timekeeping: Automatically receives time-calibration radio signals from global transmitters including US WWVB, UK MSF, Germany DCF77, Japan JJY40/JJY60, and China BPC. With both auto and manual receive functions, it maintains exceptional accuracy by syncing to atomic clock standards worldwide.
• Shock and Element Resistance: Fully sealed case and button construction provide complete protection against impacts, dust, and water. Rated for 200 meters water resistance and operational in temperatures as low as -10°C (14°F), it’s built to withstand submersion, snow, and rugged terrain.
• Altimeter with Memory: Measures altitude from -700 to 10,000 meters and stores up to 40 manual memory records. Tracks historical data including high and low altitude points, as well as cumulative ascent and descent—critical for mountaineers and hikers monitoring elevation changes.
• Digital Compass: Provides real-time directional guidance, essential for navigation in remote or featureless landscapes where GPS may be unavailable.
• Barometer with Trend Graph: Displays atmospheric pressure from 260 to 1,100 hPa and includes a tendency graph to help predict sudden weather changes, a vital tool for outdoor safety and planning.
• Thermometer: Measures ambient temperature within a range of -10°C to 60°C (14°F to 140°F), giving users immediate insight into environmental conditions.
• LED Backlight: Ensures clear visibility in low-light or nighttime conditions, allowing easy reading of all functions without external light sources.
• World Time & Alarms: Supports 31 time zones for global coordination and includes five daily alarms to keep you on schedule during missions or expeditions.
• Stopwatch & Timer: Features a 1/100-second stopwatch and countdown timer for precise timing of activities, workouts, or operational tasks.
• Solar-Powered Rechargeable Battery: Eliminates the need for frequent battery changes by harnessing light energy for continuous operation, even in low-light conditions.
