Casio G-Shock GA-100-1A1ER Features

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.

The housing is designed to shield the clock from magnetic fields.

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

Stopwatch function - 1/1000 sec. - 100 hours
Elapsed time, split time and final time are measured with 1/1000-sec accuracy. The watch can measure times of up to 100 hours.

Timer - 1/1 min. - 24 hours (with automatic repeat)
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. They then count back automatically from the preset time. The time can be set to the nearest minute and up to 24 hours in advance. 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.

Speed display
The average speed for a travelled route can be measured. Simply enter the distance at the start and press the stop watch when the destination has been reached - and the average speed is shown.

Automatic calendar
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.

Mineral glass
The tough mineral glass resists scratching.

Resin band
Synthetic resin is the ideal material for wrist straps thanks to its extremely durable and flexible properties.

2 Years - 1 Battery
The battery supplies the watch with sufficient energy for approx. two years.

Water resistance classification (20 bar)
Perfect for free diving without scuba gear: the watch is water resistant up to 20 bar according to ISO 22810.
