Watch GA-100-1A4ER

The Watch
Motorsport and adventure are the driving inspirations behind this men's G-Shock timepiece from Casio. Ultra-resistant and feature-packed, this watch sports a dual display (digital and analog) along with a seriously stylish speed indicator. Sophisticated yet understated, it works on any wrist - its black base with red accents makes it easy to pair with any look. Built tough and incredibly functional, the resin case measures 51mm in diameter and 14mm thick, topped with a mineral crystal and fitted with 4 red pushers. The stainless steel caseback is secured with screws.

The Dial
True to its motorsport DNA, this round black dial with red accents features a stunning "tapestry" guilloché checkerboard finish. It delivers a dual display: analog for time reading and digital for all other functions. Hours and minutes are indicated by silver-tone indices and a minute track. Two central hands - one in red - are skeletonized as a tribute to the steering wheels of vintage race cars.

Features:

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

World Time Function
The world time function displays the time across 29 time zones and major cities around the globe.

Stopwatch Function - 1/1000 sec - 100 h
Measures elapsed time to 1/1000th of a second over a maximum duration of 100 hours. An audible signal confirms the start and stop of the stopwatch.

Countdown Timers - 1/1 min - 24 Hours
For those who demand precision: countdown timers remind you of important or recurring events with an audible signal at your programmed date and time. Time can be set in minutes, up to 24 hours in advance - a particularly handy feature for daily medication reminders or repeated training sessions.

Automatic LED Backlight
To light up the watch display using the LED, simply tilt your wrist slightly.

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

Speed Display
Calculate your average speed over a set distance: simply enter the distance, then press the stopwatch at the start and finish - your average speed appears instantly on screen.

Antimagnetic
The case has been engineered to resist magnetic fields.

Daily Alarm

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

Button Tone On/Off
The button tone can be turned off using the mode button. Once disabled, no sound is emitted when switching between functions. However, any programmed alarms or countdown timers remain active after the button tone is turned off.

12/24-Hour Time Format
You can display the time in either 12-hour or 24-hour format.

2 Years - 1 Battery
The battery powers the watch for approx. 2 years.

Strap
This timepiece comes with a black resin strap secured by a silver-tone double-lock pin buckle. Thanks to its outstanding durability and flexibility, synthetic resin is an ideal material for watch straps.

Water Resistance
With water resistance rated at 20 atmospheres (200 meters), this model can genuinely be called a dive watch. That said, a word of caution: our watchmaking experts agree that while this timepiece handles showers, baths, swimming, and freediving with ease, it is not designed for professional scuba diving with tanks, where the pressure could compromise its water resistance. For professional divers, we recommend models rated 30 atmospheres or higher. We also advise against operating the pushers or crown while in the water to maintain optimal water resistance.
