Black GW-7900B watch - G-Shock

5 daily alarms

An audible alarm reminds you daily of your deadlines at the scheduled time. This model has five independent alarms to flexibly remind you of your important appointments.

Battery level indicator

Displays the current battery level.

Resin bracelet

Thanks to its extreme durability and flexibility, synthetic resin is an ideal material for bracelets.

Full-Auto Illuminator

When this function is activated, simply turn your wrist slightly and the watch's backlight turns on. Energy efficient: Full Auto Illuminator only works in dark environment.

Resin housing

The resin case is ideal for everyday use. It is durable, lightweight and relatively insensitive to cold, heat or other external influences.

Mineral glass

Hard, scratch-resistant mineral glass protects the watch from unsightly damage.

Automatic calendar

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

12/24 hour time format

You can display the time in 12 hour or 24 hour format.

Displaying phases of the moon

The moon phase indicator displays the current position of the moon relative to the earth.​

Tide indicator

By indicating the time of the next high tide of the chosen location, the watch will display the ebb and flow phases of that location. This can be particularly useful if you want to know in advance the behavior of the tide at your destination.

On/Off button beep

The key beep sound can be turned off with the mode key. After deactivation, there is no longer a beep when switching from one function to another. However, the programmed alarms or countdowns remain active after the button beep is deactivated.

Impact resistance

The shock-resistant structure protects the watch against impacts and vibrations.

Solar operation

Solar cells provide an autonomous and environmentally friendly energy supply. Surplus solar energy is stored in an accumulator.

Stopwatch 1/100 s - 24 hours

Measures elapsed time with an accuracy of 1/100th of a second over a maximum duration of 24 hours. The sound signal confirms the start and stop of the stopwatch.

Countdowns - 1/1 min - 24 hours

For all those who like precision: countdowns remind you of important or recurring events by emitting an acoustic signal at the programmed date and time. The time can be programmed in minutes, up to 24 hours in advance. A particularly valuable asset for daily medication or repeated training.

Loop

The bracelet is equipped with a pin buckle.

Snooze function

Every time you stop the alarm, it goes off again a few minutes later.

Waterproof class (20 bars)

Perfect for swimming and diving without equipment: the watch is water resistant up to 20 bars (ISO 22810).

Automatic time setting via reception of radio control signals (EU, USA, JPN, CHN)

Whether in Europe, North America or Japan, in the vast territories of Canada, Central America or China - once the watch is adjusted to the local time zone, it receives the corresponding radio signal and always indicates the exact date and time. In many countries, it automatically switches from summer time to winter time and vice versa.

Universal time function

The world time feature displays the time in 29 time zones and major cities around the world.
