G-Shock GA-2100-1AER Watch

The Watch
Step into the Casio world with the G-Shock watch. Built to withstand anything, its reinforced resin case in sleek black is virtually indestructible. Measuring 48.5 mm in height, 45.4 mm in width, and 12 mm thick - it sits perfectly on any wrist. Four pushers on the sides of the case give you full control over the watch's functions, from setting the time to switching modes. A scratch-resistant mineral crystal and a carbon-reinforced screw-down caseback keep the movement safe and sound.

The Dial
The black dial makes the grey hands and indices stand out, allowing for effortless time reading. On the left side of the dial, you'll find a day-of-the-week indicator with English abbreviations, and in the lower right, a window that can display world time, a countdown timer, or an alarm mode. One of the pushers also lights up the dial, and the hands feature a fluorescent coating for night visibility. Dial inscriptions include the collection name at the top and the water resistance rating.

Functions:

Dual Illuminator: When the electroluminescent backlight activates, both the digital and analog zones of the dial are lit up.

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

1/100 s Stopwatch - 24 Hours: Measures elapsed time with 1/100th of a second precision for up to 24 hours. A beep confirms both the start and stop of the stopwatch.

Countdown Timers - 1/1 sec - 24 Hours: For the precision-minded: countdown timers remind you of important or recurring events with an acoustic signal at the set date and time. Time can be programmed in seconds, up to 24 hours in advance.

Daily Alarm: The daily alarm goes off every day at the time you set. The value shown indicates the number of daily alarms available.

Hand Shift Function: This function moves the hands out of the way when they obstruct the display of the time, date, or stopwatch.

12/24-Hour Time Format: Display the time in either 12-hour or 24-hour format.

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

Neobrite: The hands and/or indices feature a fluorescent coating that keeps glowing in the dark after the watch has been exposed to a light source.

The Movement
This watch is powered by a Quartz movement for maximum accuracy. The analog display makes reading the time effortless.

The Strap
The black strap is a perfect match for the watch. Made from resin, it combines durability and flexibility without irritating your wrist. An adjustable buckle clasp ensures a secure, comfortable fit for any wrist size.

Water Resistance
This model is water-resistant to 20 atmospheres - that's 200 meters. Gentlemen, this is the watch that keeps up with you in the deep! Designed for freediving, it's built to take on serious aquatic action. You can even use it around high-pressure cleaning equipment without worry. Shower, bath, lap swimming, and freediving are all no problem. That said, for scuba diving with tanks, we recommend a timepiece with a higher water-resistance rating. Also, be sure to keep the crown and pushers locked during immersion to protect the mechanism.
