Introducing new colours for the G-SHOCK line-up of GBD-100 sports watches.

Black and white base colouring is combined with vivid light collecting resin

and semi-transparent resin for a dazzling design that contributes

to the enjoyment of a wide range of activities.

Function-wise, these models employ Bluetooth® technology to allow access

to a smartphone’s GPS for quicker calibration of distance measurements.

Once calibration is done, the watch is able to perform more accurate running

distance measurements, even when it is no longer connected to the phone.

Distance measurements used in combination with run time measurements let

you keep track of your pace, and also enable use of an Auto Lap feature that

automatically keeps track of times over a specific distance. Other standard

features include a step tracker (pedometer), interval timers (up to 20 sets of

five timers each), lap time measurement (up to 140 records for up to

100 runs), and calories burned measurement, all of which provide plenty of

support for your daily training. In addition,

new phone apps are now

available to help you configure watch settings more easily and manage your

workouts. In addition to Life Log and Activity History apps, you can

automatically create a training plan based on targets specified by you.

The displays of these watches use a high-definition MIP LCD. Super Illuminator

face illumination keeps face information easy to read, even in the dark. The soft

urethane band material provides improved comfort, while a large number of

band holes let you adjust the fit to your particular wrist. These watches

connect with your phone via Bluetooth® to support auto time adjustment,

phone notifications, step tracking, and other functions throughout the day.

Battery life is approximately two years between replacements.

The watch is equipped with energy-saving Bluetooth® technology, which

offers power-saving data transfer at the push of a button. The watch can

connect to a smartphone wirelessly via Bluetooth®, enabling access

to a wide range of useful functions.

Smartphone time

Local time will automatically be adjusted whenever the watch is connected with a smartphone.

Auto LED light

A light-emitting diode (LED) is used to illuminate the watch face, incl. the feature

of an Auto Light Switch that illuminates the display when the

watch is angled towards the face.


Shock-resistant construction protects against impact and vibration.

Calorie consumption display

This function calculates the calories you have used and stores the result in the memory.

Acceleration sensor

The motion sensor responds to acceleration and shows this as a speed on the display.

Step tracker

The watch has a built-in 3-axis accelerometer that counts the steps you take

and indicates the numbers on the display.

Training Planner

The Training Planner supports your personal training goals and gives a signal

by reaching predefined targets. For example, a specific calorie consumption or

a certain work out time can be set in advance in order to

control the workout individually.

Training Analysis

This function shows training status, fitness level and training load as well as

regeneration times. This information provides a good basis for

planning further training sessions.

Training Log

A training log stores the number of steps, calorie consumption as well as distance

and lap times and helps to compare training units.

World time function

Displays the current time in major cities and specific areas around the world.

Stopwatch function - 100 hours

Measures with an accuracy of seconds the meantime and the end time. Signals

confirm the starting/stop selection. The measuring capacity reaches up to 100 hours.

Lap memory 100

Measured total, lap and split times can be stored in a memory with the date

and can be displayed again later. A data set consists of: date, total, lap and

split times. The memory has enough space for up to 100 data sets.

5 Timer - 1/1 Sec. - 60 Min. (with automatic repeat)

The count-down timer gives a signal by reaching the set time. The measuring

capacity reaches up to 60 minutes. The timer can count back automatically

again from the preset time. Five of these countdown alarms

can be set independently.

4 daily alarms

The daily alarm reminds you about recurring events with an acoustic signal

at the time you have set. This model has four independent alarms for

flexible reminders of important appointments.

Snooze feature

Each time you stop the alarm, it sounds again after a few minutes.

Vibration alert

The vibration alarm discreetly reminds you of important appointments,

without emitting a loud signal.

Phone Finder

Misplaced your smartphone? All it takes is the push of a button on your watch

and the smartphone sounds an alarm.

Airplane Mode (Offline Mode)

At the touch of a button, the watch switches to offline mode. This means that

you can disable the wireless or GPS receiver when in the air for the

duration of the flight.

Button tones on/off

The button tones for using the mode button can be turned off. This means

that the watch no longer beeps when switching from one function to another.

Preset alarm or countdown timers remain active when the button tones

are deactivated.

Automatic calendar with Date, Day and Month

Once set, the automatic calendar always displays the correct date.

12/24-hour timekeeping

Times can be displayed in either a 12-hour or 24-hour format.

Very handy features, especially if you are a runner like me. And I love the new MIP display. Getting a 4/5 for me for two reasons: there's no milliseconds in the stopwatch and I found the plastic buckle a little scratchy at points against the bottom of my wrist (though make no mistake, the watch is definitely comfortable to wear). But another solid offering from G-Shock!
