Description (7,292 characters)
Set contents: Body, box, instruction manual, warranty card are included in the instruction manual
Reinforced waterproof for daily life: 20BAR
Mobile link function that can be linked to the function via Bluetooth communication with compatible smartphones
Shock-resistant structure that resists shock and vibration
Dust- and mud-proof construction that prevents mud and dust from entering the watch
Triple sensor capable of measuring azimuth, altitude / pressure and temperature
Carbon core guard structure that protects the module from external impact with a carbon case Product introduction Newly adopted carbon material from the master of G series `` Mad Master ''
that is supposed to be used on the extreme land where rubble and earth and sand are piled up and scattered New model of structure appears
By using carbon of high rigidity material for the case, damage and deformation due to impact etc. are suppressed, and high air tightness is secured without a metal button pipe
In addition, it is equipped with a filter that prevents mud from entering, realizing dustproof and mudproof performance that can withstand harsh environments.
Also equipped with a stainless steel panel back that keeps it airtight and a fine resin back cover with glass fiber that resists impact.
In pursuit of practicality and toughness, we adopted a design that mimics a gasoline carrying can installed on off-road vehicles running on rough roads.
The bezel has a three-layer structure in which a carbon fiber sheet is inserted into a fine resin.
By making the finest resin in the top layer transparent, we finished the bezel where you can see the carbon texture.
In terms of functionality, in addition to a small sensor that can measure azimuth, altitude / atmospheric pressure, and temperature, a built-in acceleration sensor that can measure the number of steps realizes a quad sensor.
Supports land missions by making it easier to understand changes in the natural environment and activity history
In addition to easy time adjustment by linking with the G-SHOCK dedicated app, a new "Mission Log Function"
Automatic recording of altitude obtained with the watch and route obtained with the GPS of the smartphone in the app
Plot altitude points obtained by manual operation on the trajectory
Furthermore, calorie consumption is calculated from the altitude + step count value, taking the lifting elements into account, and recorded as an activity log.
In the “location indicator function”, if you record the current location on the app by operating the button on the clock, you can also display the direction to the recording point on the second hand and the distance on the LCD
Also newly equipped with "mode switching / customization function"
It is now possible to customize settings such as mode ON / OFF and display switching on the application, using only necessary functions and changing the display order according to the application.
Pursuing ruggedness, operability, and ease of installation that can be used in harsh environments
Introducing a toughness watch equipped with a sensor function and smartphone linkage function that supports quick judgments and accurate actions in various situations.
・ Shock-resistant structure
・ Dust-proof and mud-proof structure
・ 20 standard atmosphere waterproofing function
・ Mobile link function (function linked by Bluetooth communication with compatible mobile phones)
・ Needle retraction function (If the needle overlaps the LCD display and is difficult to see, the needle can be temporarily retracted from the LCD display.)
・ Azimuth measurement function: Measure 16 azimuth and azimuth angles (0 to 359 °), continuous azimuth measurement (60 seconds), north directional pointer function, magnetic declination correction function, azimuth correction function (2-point correction / 8 character) (Correction / automatic correction)
・ Barometric pressure measurement function (measurement range: 260 to 1,100 hPa), atmospheric pressure trend graph (displays the past 20 hours or 56 hours), atmospheric pressure difference indicator (± 10 hPa), atmospheric pressure trend information alarm (characteristic changes in atmospheric pressure) (If it happens, you will be notified with an arrow and a sound report) * The barometric trend graph can be changed to the past 20 minutes or 56 minutes display
The pressure difference indicator at that time is displayed in units of ± 1 hPa.
・ Altitude measurement function / relative altimeter (measurement range: -700 to 10,000m), altitude memory (measurement date / time / altitude up to 14 manual memories, automatic recording data: maximum / minimum altitude, auto integration (increase) / Descent) memory), altitude trend graph, altitude difference indicator (± 100m / ± 1000m), measurement interval setting function (every 5 seconds / 2 minutes) * 1 second only for the first 3 minutes
・ Temperature measurement function (measurement range: -10 to 60 ℃)
・ Step count function (step display range: 0 to 999,999 steps), power saving function (automatically puts the sensor to sleep when there is no movement for a certain period of time)
・ Sunrise / sunset time display
World time: 38 cities (38 time zones, daylight saving time automatic setting function) + UTC (universal coordinated time) time display, home time city replacement function
・ Stopwatch (1/100 second (less than 1 hour) / 1 second (1 hour or more), 24-hour counter, with split)
・ Timer (set unit: 1 minute, maximum set: 24 hours, measured in 1 second units)
・ Five time alarms
・ Time signal
・ Full auto calendar
・ 12/24 hour display switching
・ Operation sound ON / OFF switching function
・ Double LED light: LED light for dial (auto light, super illuminator, afterglow function, afterglow time switching (1.5 seconds / 3 seconds)), LED backlight for LCD part (auto light, super illuminator, afterglow function) , With afterglow time switching (1.5 seconds / 3 seconds)) * When not linked with a smartphone, it operates with normal quartz accuracy (average monthly difference of ± 15 seconds)
* GG-B100 is certified by Japan Radio Law
Brand introduction G-SHOCK has built a new concept of toughness on watches
It all started with a developer's passion for creating a watch that would not break even if dropped, and a reckless challenge that overturned the common sense of the time.
Over 200 prototypes have been repeated, and about two years have been spent, and the shock-resistant structure has been completed.
It is the birth of technology to play the core of toughness
Since then, G-SHOCK has continued to evolve endlessly
Structure, material, function
Pursuing further toughness in every aspect
