Watch GA-100-1A1ER

The Watch
This Casio timepiece delivers exceptional value for money along with a youthful, on-trend, sporty aesthetic - tempered by an understated all-black look. The matte black, almost military-inspired finish pairs effortlessly with virtually any outfit. Built tough from high-performance materials and packed with features, this versatile watch houses a 51mm diameter, 14mm thick resin case topped with a mineral glass crystal and equipped with 4 pushers. The stainless steel caseback is secured with screws.

The Dial
The round black dial is reminiscent of a fighter jet cockpit with its array of flight and control instruments. It features a dual display: analog for time reading and digital for additional functions. Hours are marked by horizontal white bar indices around the dial edge, minutes by a minute track, and two central white hands are used to read the time.

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.

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

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 watch comes with a black resin strap secured by a silver-tone 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.
