The G-Shock/VLC Distribution G-Shock Tactical Rangeman “Keep Time” Blackout (Model GW94001B, UPC 889232252193) is a mission-ready survival watch built for serious outdoorsmen, first responders, military, and anyone who needs a timepiece that can take real abuse. Part of the MASTER OF G Rangeman series, this blackout tactical model combines legendary G-Shock toughness with advanced Triple Sensor tech, solar charging, and atomic timekeeping in a stealth all-black package sized for 145–215mm wrists.
Tactical “Blackout” Design Built for Extreme Environments
The GW9400-1B Tactical Rangeman is designed for harsh natural environments – desert, jungle, mountains, and everything in between.
Stealth black resin case and band that minimize reflections and visual signature
Inverted (negative) LCD for a “blackout” look that still keeps key info visible at a glance
Oversized guarded buttons with a cylindrical button guard structure that protects the sensor button from side impacts and guides your press for confident operation even with gloves.
This watch is built to be shock resistant, mud resistant, and water resistant to 200 meters, so you can wear it in heavy rain, mud, sand, surf, and snow without worrying about failure.
Triple Sensor: Compass, Altimeter/Barometer & Thermometer
At the heart of the Tactical Rangeman “Keep Time” is Casio’s proven Triple Sensor system, putting critical environmental data right on your wrist:
Digital Compass – quickly check bearing and direction for land navigation and tactical movement.
Altimeter – track elevation changes while hiking, climbing, or operating in mountainous terrain.
Barometer – monitor barometric pressure to watch for weather changes and storms.
Thermometer – measure ambient temperature to help manage hydration, clothing layers, and mission planning.
A dedicated sensor button instantly calls up the last-used sensor mode, and three different indicator tones tell you which sensor is active, allowing almost no-look operation so your eyes can stay on your surroundings.
Solar Powered with Multi-Band 6 Atomic Timekeeping
The GW94001B is designed to “keep time” no matter where you are:
Tough Solar rechargeable battery – charges from sunlight and indoor light, so you don’t have to worry about regular battery changes. Typical operation is about 7 months on a full charge without further light exposure.
Multi-Band 6 atomic timekeeping – automatically receives radio time signals (where available) to keep your watch synchronized with atomic clocks in the U.S., Europe, Japan, and China.
Power saving and battery level indicator – conserves energy when not in use and lets you check remaining power at a glance.
For tactical users, travelers, and outdoor professionals, that means ultra-reliable, low-maintenance timekeeping you can trust far from civilization.
Rugged Survival Toolset on Your Wrist
Alongside the Triple Sensor, the Rangeman GW-9400-1B packs a full suite of survival-oriented functions:
World Time: 31 time zones, 48+ cities + UTC – quickly switch between home and mission time zones.
Sunrise/Sunset Times: Know first and last light times for navigation, movement, and hunting.
1/100-second Stopwatch: Up to 999:59’59.99” – ideal for training, timing drills, or mission events.
Countdown Timer: Up to 24 hours – useful for operations, workout intervals, or reminders.
5 Daily Alarms + 1 Snooze Alarm and hourly time signal.
Full Auto Calendar to 2099 – set it once and forget it.
Full Auto LED “Super Illuminator” Backlight with selectable afterglow (1.5 or 3 seconds) for low-light readability.
There’s also a 40-record sensor memory (time-stamped) so you can log altitude or barometric readings over time, ideal for tracking climbs, fronts, or mission checkpoints.
All-Day Comfort and Mission-Ready Fit (145–215mm)
Sized to fit wrists from 145–215mm, this Rangeman works for a wide range of wearers—from smaller wrists to larger tactical builds.
Case size: approx. 55.2 × 53.5 × 18.2 mm – big, readable, and glove-friendly.
Weight: about 93 g – substantial enough to feel tough, but still comfortable for all-day wear.
Resin case and band resist sweat, mud, and impacts while staying comfortable against the skin.
Mineral glass crystal protects the digital display from scratches and knocks in the field.
The result is a watch that can handle rucks, range sessions, wet weather, and everyday use without beating up your wrist.
Blackout Master of G – Tactical Look, Everyday Versatility
The “Blackout” Tactical Rangeman aesthetic is ideal for:
Law enforcement, military, and security who want a watch that won’t draw attention or reflect light.
Hunters and outdoorsmen who prefer subdued gear that blends into natural surroundings.
EDC enthusiasts who love the stealth, all-black style of modern tactical watches.
Despite its hardcore credentials, the GW94001B still looks great with everyday streetwear, casual outfits, or work uniforms.
