The Watch

Casio has carved out a defining place in watchmaking with its rugged, precision-engineered timepieces. Driven by innovation and expertise, the brand crafts highly capable watches built to be everyday essentials for any occasion. Discover the GA-010-5AER - a bold yet wearable watch for daily life. It houses an octagonal case crafted from carbon and bio-resin for exceptional durability. Weighing 67 g, it measures 55.10 mm in length, 52 mm in width, and 17.50 mm in thickness. Five pushers positioned around the case control the various dial functions visible through the mineral crystal. A bold bezel surrounds the crystal, engraved with key function indicators. The case features an engraved caseback secured by screws, ensuring water resistance to 20 ATM.

The Dial

This dial features a super illuminator LED backlight with adjustable duration for optimal readability. Set against a black background, the digital display at the bottom shows the day of the week in English, the current date and month, along with functions such as snooze, alarm, and signal. A minute track and grey hour indexes frame the display, with two luminescent hands anchored at the center. Coated with a Neobrite treatment, they ensure reliable reading of hours and minutes in low-light conditions. At 11 o'clock, a window displays the chronograph functions, flanked on the right by an additional counter for the small seconds. The brand name and collection name at 9 o'clock complete the dial as a signature.

The Functions

World Time Function

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

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

Countdown timers - 1/1 sec - 1 hour

For those who live by precision: countdown timers alert you to important or recurring events with an audible signal at the set date and time. Program in seconds, up to 1 hour in advance - perfect for daily medication reminders or repeated training intervals.

5 daily alarms

A daily audible alarm reminds you of upcoming deadlines at your scheduled time. This model features five independent alarms, giving you the flexibility to stay on top of all your important appointments.

Snooze Function

Every time you silence the alarm, it goes off again a few minutes later.

Button beep on/off

The button beep can be muted using the mode button. Once muted, no beep sounds when switching between functions. However, any programmed alarms or countdown timers remain active even after the button beep is turned off.

Hand shift function

This function lets you shift the hands when they obstruct the display of the time, date, or stopwatch.

Auto Calendar

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

12/24-Hour Time Format

Display time in either 12-hour or 24-hour format.

The Movement

This timepiece is powered by a quartz movement with an accuracy of ±15 seconds per month. Manufactured in-house, this caliber is engineered for vibration resistance and reliable function performance. It runs on a CR2025 battery for an impressive power reserve of approximately 10 years.

The Bracelet

Thanks to its durability, flexibility, and lightweight feel, this bio-resin strap delivers all-day wearing comfort. It suits every occasion and sits elegantly on your wrist. The khaki green hue adds a laid-back edge that completes any look. Secured with a pin buckle for easy adjustment, it fits wrist sizes from 145 to 215 mm.

Water Resistance

This model offers water resistance to 20 atmospheres, or 200 meters. A watch that's ready to go wherever your aquatic adventures take you - including freediving. You can also use it around high-pressure washers without worry. Showering, bathing, lap swimming, and freediving are all fine. That said, for scuba diving with tanks, we recommend a timepiece with a higher water resistance rating. Also, avoid operating the crown or pushers while submerged to protect the movement.
