GWF-D1000B-1ER G-SHOCK Casio Frogman gents watch

Moon Phase Indicator

The moon phase indicator shows the current moon phase based to the earth

Tide indicator

Once the high tide time has been entered for a selected location, the watch can display the low and high tide phases at this location on any given date. This can be quite useful, for example, if you want to know the patterns of the tides at your destination in advance.

Depth gauge to -80 m

A pressure sensor measures changes in water pressure and converts the result into a depth display. Dives down to -80 m can be displayed.

Diver's Log

Data such as dive time, water temperature and dive depth can be saved and called up at a later date.

Surfacing alert

The watch issues an alert if the diver surfaces at a speed of more than 10 m/min., meaning the diver is not in compliance with the relevant decompression times.

World time function

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

Stopwatch function - 1/100 sec. - 100 hours

Elapsed time, split time and final time are measured with 1/100-sec accuracy. The watch can measure times of up to 100 hours.

Timer - 1/1 min. - 24 hours

For fans of precision: the countdown timers help you to remember specific or recurring events by giving off an audible signal at a preset time. The time can be set to the nearest seconds and up to 24 hours in advance. This model has three independent timers - ideal for people who need to take medicines every day or those who do interval training.

5 daily alarms

The daily alarm reminds you about recurring events with an acoustic signal at the time you have set. This model has 5 independent alarms for flexible reminders of important appointments.

Snooze feature

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

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.

Screw locked back

The screw connection on the base of the housing optimally protects the inner workings of the watch and simultaneously provides easy access, when changing the battery for example.

Carbon-resin wrist strap

On their own, carbon and resin are stress-resistant and durable — together they create a wrist strap that is extra robust and extremely durable. And the "carbon design" on the wrist strap not only looks elegant, it also lends the watch a sporty, dynamic touch.

Folding clasp

The watch has a folding clasp.

Battery level indicator

An indicator shows the current battery level.

This model is water tight after ISO 200 and withstands water pressure to a depth of 200 m.
