Product description
This model from the G-SHOCK MASTER OF G series, designed to support men who brave harsh natural environments, features a bold design accented with emergency yellow. The Rangeman GW-9400 is equipped with a triple sensor for altitude, direction, and barometric pressure/temperature. The sensor buttons feature a “Button Guard Cylinder Structure” for smooth and accurate operation. Pressing the sensor button directly displays the most recently used sensor mode, and it also features three levels of audible alerts, allowing for intuitive operation. It also features a carbon fiber insert band and metal parts for the buttons, side screws, and keeper ring. The G-SHOCK Rangeman is packed with the functionality you need for extreme environments.
●Shock resistant
●Tough Solar (solar charging system)
●200-meter water resistance
●Radio wave reception function: Automatic reception (up to 6 times per day) (up to 5 times per day for Chinese radio waves) / Manual reception, <Japan> Received radio waves: JJY, Frequency: 40 kHz/60 kHz (model compatible with both Fukushima and Kyushu stations) <North America> Received radio waves: WWVB, Frequency: 60 kHz <Europe> Received radio waves: MSF/DCF77, Frequency: 60 kHz/77.5 kHz <China> Received radio waves: BPC, Frequency: 68.5 kHz *When the home time setting is set to a city that can receive radio waves, the station corresponding to that city will be received. The time zone corresponding to the selected city will also be set.
●World time: Time display for 48 cities worldwide (31 time zones, daylight saving time setting function) + UTC (Coordinated Universal Time)
●Compass measurement function: Measures 16 azimuths and azimuth angles (0 to 359°), continuous azimuth measurement (60 seconds), graphic display of north, south, east, west, bearing memory (memorizes one graphic showing the azimuth angle and recorded direction), magnetic declination correction function, azimuth correction function
●Barometric pressure measurement function (measurement range: 260 to 1,100 hPa), barometric pressure trend graph display (displays the past 42 hours), barometric pressure difference graphic, barometric pressure trend information alarm (indicates significant changes in barometric pressure with an audible alarm and arrow)
●Altitude measurement function/relative altimeter (measurement range: -700 to 10,000 m), altitude memory (automatically recorded data: maximum altitude, minimum altitude, accumulated ascent altitude, accumulated descent altitude), altitude difference graphic, altitude difference measurement (-3,000 ~3,000m), measurement interval setting function (every 5 seconds/2 minutes) *Every 1 second for the first 3 minutes only
●Temperature measurement function (measurement range: -10 to 60°C)
●Manual memory function: Records up to 40 records of altitude, air pressure, temperature, direction, and time (timestamp function)
●Sunrise and sunset time display
●Stopwatch (1/100 second, 1000 hour counter, with split)
●Timer (set unit: 1 minute, maximum set: 24 hours, measured in 1 second increments)
●5 time alarms (only 1 with snooze function) and hourly signal
●Battery indicator display
●Power saving function (in dark places, the display is turned off after a certain period of time to save power)
●Full auto calendar
●12/24 hour display switching
●Operation sound ON/OFF switching function
●LED backlight (with full auto light, super illuminator, afterglow function, afterglow time switching (1.5 seconds/3 seconds))
* If radio wave reception is not possible, the watch will operate with normal quartz accuracy (average monthly deviation of ±15 seconds).
*The altimeter is a relative altimeter that converts changes in air pressure into altitude. If air pressure changes due to weather conditions, the measured altitude will also change.
