Casio is a Japanese brand founded by Tadao Kashio and celebrated for its innovative craftsmanship. It also produces robust, reliable timepieces built to accompany you on your greatest adventures. Synonymous with durability, its models are made from solid materials and powered by advanced mechanisms for a unique watchmaking experience. Today, the iconic Japanese brand invites you to discover this GMA-P2100BB-1AER watch in an all-black look, designed to complement the wrists of both men and women. It features a fully black durable resin octagonal case that is shock-resistant and measures 40.20 mm in diameter and 46 mm in length, with a thickness of 11.20 mm. Four silver pushers provide access to all the available functions. The surface reveals a black bezel engraved with button function labels, surrounding a mineral crystal over the dial. Finally, this model offers 20 ATM water resistance, secured by a screw-fixed case back.

The Dial

This LED-illuminated dial is clean and refined, delivering reliable readability at a glance. It features a black background with a minute railroad track around the edge and luminescent hour markers. Two luminescent hands sweep from the center, providing clear hour and minute readings in any condition. An LCD screen with digital display appears at approximately 4 o'clock, showing the time in digital format along with the current date, day, and month, plus the alarm and stopwatch. The dial is signed with the collection name and brand name below 12 o'clock.

The Functions

World time function

The world time function displays local time across 29 different time zones.

Stopwatch 1/100 sec - 24 hours

Measures elapsed time to 1/100th of a second, up to a maximum of 24 hours. An audible signal confirms both the start and stop of the stopwatch.

Countdown timers - 1/1 sec - 24 hours

For precision lovers: countdown timers keep you on top of recurring or important events by sounding an alert at the set date and time. Time can be set in seconds, up to 24 hours in advance.

5 daily alarms

A daily alarm sounds at your programmed time to keep you on schedule. This model includes five independent alarms for maximum flexibility with your most important appointments.

Hand shift function

This function allows the hands to be moved when they obstruct the visibility of the time, date, or stopwatch display.

Key beep on/off

The key beep can be turned off using the mode button. Once disabled, pressing any button to switch functions will no longer produce a beep. However, any programmed alarms or countdown timers remain active after the key beep is turned off.

Automatic calendar

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

12/24-hour time format

You can display the time in either 12-hour or 24-hour format.

The Movement

At the heart of this watch beats a quartz movement manufactured by Casio. This Japanese mechanism ensures vibration resistance and drives all functions with pinpoint accuracy. It is powered by a battery giving this timepiece approximately 3 years of autonomy.

The Strap

Striking and resilient, this strap is crafted from durable resin - flexible, sturdy, and lightweight for comfortable all-day wear. Suited to active lifestyles, it comes in a versatile black tone that pairs with any look, and fastens with a pin buckle for easy adjustment.

Water Resistance

With a water resistance of 20 atmospheres - equivalent to 200 meters - this model earns the title of "dive watch" without hesitation. Our watchmaking experts agree: while it handles showers, baths, lap swimming, free diving, and recreational scuba with ease, it is not designed for extreme deep-sea diving where pressure would eventually compromise its seal. For professional divers tackling serious depths, we recommend models rated 30 atmospheres and above. We also advise against operating the pushers or crown while submerged, to maintain a perfect water-tight seal!
