Casio unveils its latest model, the GW-M5610U-1ER, from the G-Shock collection. This contemporary-looking watch is the perfect companion for your active lifestyle. It features a black resin case, prized for its light weight and durability. The octagonal case measures 46.7 mm in length, 43.2 mm in width, and 12.7 mm in thickness - dimensions that sit perfectly on men's wrists. A mineral crystal shields the dial from knocks and scratches. 4 pushers give you access to a wide range of features. Finally, the screwed caseback ensures water resistance of 20 atmospheres, equivalent to 200 meters of depth.
Rectangular in shape, the gray dial framed in black and red offers a digital readout. You can read the hours, minutes, and seconds in digital 12/24-hour format. It is complemented by real-time date and day display via the automatic calendar. This dial also features the Illuminator function, ensuring optimal readability day and night. Finally, the brand signs its creation at the top of the dial and notes the water resistance rating at the bottom.
Shock Resistance
The shock-resistant structure protects the watch against impacts and vibrations.
Solar Power
Solar cells provide autonomous, eco-friendly energy. Any surplus solar energy is stored in a rechargeable battery.
Full Auto Illuminator
When this function is enabled, a slight flick of the wrist automatically lights up the watch's backlight. Energy-efficient by design, the Full Auto Illuminator only activates in dark environments.
Countdown Timer - 1/1 Min - 24 Hours
For precision enthusiasts: countdown timers remind you of important or recurring events with an audible signal at the set date and time. The timer can be programmed in seconds, up to 24 hours in advance.
Automatic time synchronization via radio signal reception (EU, USA, JPN, CHN)
Whether you're in Europe, North America, Japan, the vast territories of Canada, Central America, or China - once the watch is set to the local time zone, it picks up the corresponding radio signal and always displays the exact date and time. In many countries, it automatically switches between daylight saving time and standard time.
World Time Function
The world time function displays the time across 29 time zones and major cities worldwide.
1/1-Min Countdown Timer - 24 Hours
For precision enthusiasts: countdown timers remind you of important or recurring events with an audible signal at the programmed date and time. The timer can be set in minutes, up to 24 hours in advance - a particularly handy feature for daily medication reminders or repeated training sessions.
Snooze Function
Each time you stop the alarm, it goes off again a few minutes later.
Daily Alarm
The daily alarm triggers every day at the time you set. The value shown corresponds to the number of daily alarms available.
Automatic Calendar
Once programmed, 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.
Button Beep On/Off
The button beep can be turned off using the mode button. Once disabled, no beep will sound when switching between functions. However, any programmed alarms or countdown timers remain active after the button beep is turned off.
To deliver a quality digital display, this watch is powered by a solar movement. At the heart of the case, a solar sensor converts artificial or natural light into energy, enabling precise readout of hours, minutes, seconds, day, date, and a host of additional functions.
A resin bracelet rounds out this watch. Black in color, it delivers lasting durability and flexibility on your wrist. It adjusts and fastens easily with a pin buckle.
With water resistance of 200 meters - 20 ATM in proper watchmaking terms - this watch is built for shallow-water diving. It can handle showers, baths, and swimming in the ocean or pool for non-professional freediving. For professional scuba diving with tanks, our Ocarat watch team has handpicked 30 ATM models for you - find them on our site with a quick additional search. One last reminder: never operate the pushers or crown while in the water!
