G-Shock GA-2100-4AER Watch

The Watch
Casio presents its G-Shock watch - a timepiece built for toughness. The reinforced resin case is proof of that, measuring 48.5 mm tall, 45.4 mm wide, and 12 mm thick: ideal proportions for men's wrists. A scratch-resistant mineral glass protects the watch from potential damage. Four push buttons on the case let you control all the watch's functions. Finally, a screw-back case back ensures water resistance to 20 ATM - more than enough for underwater exploration.

The Dial
The round, red dial rounds out the watch's bold look. Inside, two hands indicate hours and minutes, accented by indices. On the left side of the dial, a sub-hand displays the day's initials, while a digital screen in the lower right shows world time, a stopwatch, or an alarm mode. One of the push buttons lights up the dial and hands, and the indices feature a fluorescent coating - perfect for reading the time in the dark. The G-Shock collection name is printed at the top of the dial.

Features:

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

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

1/100 sec Stopwatch - 24 Hours: Measures elapsed time with 1/100-second precision for up to 24 hours. An audible beep confirms the start and stop of the stopwatch.

Countdown Timer - 1/1 sec - 24 Hours: For precision lovers: countdown timers alert you to important or recurring events with an audible signal at the set date and time. The countdown can be programmed in seconds, up to 24 hours in advance.

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

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

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 disabled using the mode button. Once turned off, there is no longer a beep when switching between functions. However, any programmed alarms or countdowns remain active after the button beep is disabled.

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
The watch is powered by a quartz movement for maximum precision, ensuring reliability and robustness. The analog display makes reading the time effortless.

The Strap
A red resin strap completes the watch. Thanks to the material used, this strap delivers both durability and flexibility - ideal for any wrist. An adjustable pin buckle lets you dial in the perfect fit.

Water Resistance
This model offers water resistance to 20 atmospheres (200 meters). Gentlemen, this is a watch built for serious aquatic adventures - including freediving. And since it laughs at water, you can even use a high-pressure washer with this timepiece on your wrist. Showering, bathing, lap swimming, and freediving? All good. That said, for scuba diving with tanks, we recommend a timepiece with a higher water resistance rating. Also, avoid operating the crown or push buttons during submersion to protect the movement's integrity.
