About the Watch in short. Until recently, the only representative of the G-Shock Rangeman line was to survive in harsh environmental conditions. The case is designed in such a way as to withstand the most aggressive conditions – strong impacts, dust and dirt will not do any harm to the watch. Brutal appearance and a fully electronic dial will appeal to serious men. For those who often have to be left alone with nature and its whims, the GW-9400 has a triple sensor – the barometer can not only predict the weather by changes in atmospheric pressure, but also show altitude, the thermometer measures air temperature, and digital the compass will indicate the correct direction of travel. To monitor solar activity, there is a function of showing the time of sunrise / sunset at any point in the world. Thanks to the solar battery, the watch will not let you down at the most crucial moment, and the radio synchronization function automatically corrects the time for the most accurate radio towers. The basic functionality also has not gone anywhere – a stopwatch, timer, alarm clock, world clock and a bright automatic display backlight.

Altimeter Mode
The watch takes altitud readings and displays results based on air pressure measurements taken by a built-in pressure sensor. It also saves various types of altitude records and data.
Barometric Pressure and Temperature Readings
This watch uses a pressure sensor to measure air pressure (barometric pressure) and a temperature sensor to measure temperature.
Using the Stopwatch
The stopwatch measures elapsed time, split times, and two finishes.
Using the Countdown Timer
The Countdown timer can be configured to start at a preset time, and sound an alarm when the end of the countdown is reached.
1. Use (D) to select the Countdown Timer Mode (TMR).

PROs
+ atomic timekeeping
+ easy to read
+ carbon fiber band
+ barometer
+ altimeter
+ solar charging
+ quick-start stopwatch
+ fit well
+ the style is good and I like the negative display. I see the time pretty well for having aging eyes. Great watch
CONs
– some indicators are fairly small
– the rangeman is old
– the numbers on the all black are not easy to read
– the buttons should have been a darker gray and the buckle should have been black
What we like in GW-9400 *comments by experts with 10 years experience in writing about Casio watches
— 200-meter water resistance (good for swimming but not for deep diving)
— Tough Solar (CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power)
— Radio-controlled Watch; Multi band 6 (additional way for time sync. This watch receives time calibration radio signals that keep the displayed time accurate)
— Digital compass (measures and displays direction as one of 16 points)
— Thermometer (can measure and display the outside temperature in a range from -10 C to 60 C)
— Barometer (measures the air pressures and displays tendencies in the weather)
— Altimeter (The electronic mechanism “estimates” the altitude based on the air pressure)
— Sunrise, sunset time display (Sunrise time and sunset time for specific date, daylight pointers)

These are not all G-Shock GW Series. Here is a list of All G-Shock GW Watches →
Official Casio Description. Introducing RANGEMAN, the latest addition to the Master of G series of tough and rugged timepieces that are designed and engineered to stand up to the most grueling conditions imaginable. RANGEMAN is Triple Sensor equipped, which makes it capable of keeping altitude, barometric pressure, temperature, and direction readings at your fingertips.
Cylindrical buttons provide outstanding operation and improved resistance to impact. The frequently used sensor button (center right) has a metal cover that protects it against lateral impact and keeps foreign matter out. Pressing the sensor button in any mode takes you directly to a sensor screen. Each sensor mode has its own audible tone, which means you can determine which mode you are entering without even looking at the watch.
All of this plus one-touch time recording, one-touch elapsed time measurement, world-renowned G-SHOCK toughness and durability, and much more makes RANGEMAN the perfect choice for rangers, rescue crews, and anyone else whose profession or activities demand unfailing reliability.

Solar Power. None-Stop – A solar panel converts even weak illumination from fluorescent lighting into electric power. A rechargeable battery with a large power storage capacity supports stable operation of various functions with high electricity consumption. You never have to worry about the battery running down because it’s a solar battery. Casio watches with solar technology, receive thermal and electrical energy that recharges the watch batteries through solar panels on the face of the watch.
MultiBand 6. Terrestrial radio wave reception from 6 transmission stations worldwide. Automatic time correction available in Japan, North America, UK, Europe and China.
— Reception is possible even when surrounded by buildings.
— Signals are received during the night to keep the displayed time exact. — Reception is possible with less than normal power consumption.

You ask, we answer…
CASIO’s original solar-charging system that converts not only sunlight but also light from fluorescent lamps and other sources into power.
This is additional way for time sync. This watch receives time calibration radio signals that keep the displayed time accurate.
It measures the air pressures and displays tendencies in the weather.
The electronic mechanism “estimates” the altitude based on the air pressure.
