Watch Capsule Two Tone Utility Colours GA-100TU-1A3ER

The Watch

Casio is a renowned Japanese brand founded in 1946 by Tadao Kashio, celebrated for watches built to perform in extreme conditions - thanks to innovative materials and cutting-edge features. Discover the Capsule Two Tone Utility Colours GA-100TU-1A3ER model, a limited edition men's timepiece from the iconic G-Shock collection, crafted from durable resin for all-condition resilience. Its imposing round black case measures 51.20 mm in diameter and 16.90 mm in thickness, with a length of 55 mm and a weight of 72 g. Four pushers give easy access to all functions, with their labels marked on the bezel. The bezel surrounds a mineral crystal over the dial, and the whole is sealed by a four-screw case back ensuring 20 ATM water resistance.

The Dial

This dual-display dial delivers precise timekeeping at a glance. It features a black background with square patterns framed by a minute railroad track around the edge. Hour markers line the track, and together they are swept by two skeletonized hands anchored at the center - coated in a luminescent treatment along with the hour indices for optimal low-light readability. The shorter hand marks the hours and the longer the minutes. At 4 and 8 o'clock, two rectangular Super Illuminator screens provide reliable digital display in any condition: the first shows abbreviated day of the week and seconds, while the second displays the current date and month. Two additional sub-dials sit at 2 and 12 o'clock, with a round window at 10 o'clock indicating functions such as alarm and snooze. The first sub-dial shows speed and the second the 1/1000th stopwatch. Around the dial, the brand name, water resistance rating, and collection name are signed at 6 o'clock.

The Functions

World time function

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

Stopwatch 1/1000th sec - 100 hours

Measures elapsed time to 1/1000th of a second, up to a maximum of 100 hours. An audible signal confirms both the start and stop of the stopwatch.

Countdown timers - 1/1 min - 24 hours (with auto-repeat)

For precision lovers: countdown timers keep you on top of recurring or important events by sounding an alert at the set date and time, then automatically counting down from the pre-programmed value. Time can be set in minutes, up to 24 hours in advance - perfect for daily medication reminders or repeating workout intervals.

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.

Snooze function

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

Speed display

You can calculate your average speed over any distance. Simply enter the distance, then start and stop the stopwatch at the beginning and end - your average speed appears instantly on screen.

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

This timepiece is powered by a quartz movement manufactured by Casio. This Japanese mechanism delivers strong vibration resistance and exceptional accuracy across all its functions. It features a magnetic shield for optimal magnetic resistance, and a battery guaranteeing approximately 24 months of autonomy.

The Strap

This sporty strap adds effortless character with its attractive olive green tone. Crafted from resin - a material prized for its exceptional durability and flexibility - it ensures comfortable everyday wear and stands up to extreme activities. It fastens with a double pin buckle in silver.

Water Resistance

With 200-meter water resistance - or 20 ATM in the precise language of watchmaking - this watch is built for shallow-water diving. It comfortably handles showers, baths, sea and pool immersion, and recreational free diving. That said, for professional scuba diving, our Ocarat watch specialists have handpicked 30 ATM models available in our catalog. One final word of advice: avoid operating the pushers or crown during any water activity to preserve a perfect seal!
