Casio has released its latest fitness-oriented digital watches, the G-Shock G-Lide GBX-H5600 series, in the US market. Following an initial launch in Japan earlier this spring, the new models are now available for $330. The GBX-H5600 integrates modern health tracking hardware, including an optical heart rate monitor, into the familiar square G-Shock profile, specifically targeting surfers and outdoor users.

Design Details

The lineup debuts with two models: the black GBX-H5600-1 and the blue GBX-H5600-2. Both feature a translucent bezel and a solid band made from bio-based resin. Casio has managed to reduce the weight of these watches to 47 grams, making them roughly 12 grams lighter than the older DW-H5600 models. This weight reduction is primarily due to a new case back constructed from carbon fiber-reinforced resin.

For the display, Casio is using a high-resolution Memory-in-Pixel (MIP) LCD. MIP panels are standard for outdoor sports watches because they remain highly legible in direct sunlight, which is a necessary practical feature for a device intended for the beach.

Internally, the GBX-H5600 functions as a standard fitness tracker. It includes an optical sensor for heart rate monitoring and blood oxygen level estimates, along with a three-axis accelerometer to track steps, distance, and pace. The software supports multi-sport tracking, sleep analysis, and cardio load measurements.

Because this watch is part of the surf-focused G-Lide series, it also includes tide graphs, moon phase data, and sunrise/sunset times. The watch can be connected to the smartphone app via Bluetooth to load location-specific tide patterns from a database of about 3,300 global surf spots directly to the device.

As a connected watch, it handles basic smart functions. It mirrors smartphone notifications for calls, emails, and social media, and includes a phone finder feature alongside automatic time adjustment.

Power management relies on a hybrid system of USB and solar-assisted charging. If you leave the heart rate monitor running continuously during activities, the battery lasts a maximum of 35 hours. If you turn off the heart rate tracking and use it as a standard digital watch, a single charge lasts about a month. The power-saving mode extends that standby time to roughly 11 months.

In related news, Casio has recently brought its Japanese red lantern-inspired Aka-Chochin G-Shock watches to the US, while also unveiling a new translucent G-Shock model influenced by 1990s streetwear culture.

Casio is releasing two new G-Shock watches in the US this month. The DW-6900AKA-4 and DW-5600AKA-4, which originally debuted in Japan in April, are now available stateside for $190 each. Both watches are part of the Aka-Chochin series, a lineup designed to look like the traditional red paper lanterns often hung outside taverns in Japan.

Design Details

From a design perspective, the updates here are cosmetic. Both models feature a red case and band made from bio-based resin, a material Casio has been using more frequently across its recent lineups as an alternative to standard plastics. To contrast the red exterior, the watches use black buttons and a black band loop, a detail meant to resemble the dark lacquered holders of the paper lanterns.

On the dial, Casio added kanji characters that translate to shock resistance. Another detail tied to the theme is the LED backlight. Instead of the standard white light, these models use a warmer, orange-tinted glow to mimic a lit lantern in the dark. The watches also include a custom engraving on the case back and ship in themed packaging.

Underneath the red resin, these are standard 5600 and 6900 series G-Shocks. The DW-5600AKA-4 uses the familiar square case design, measuring 48.9 by 42.8 by 13.4 mm and weighing 53 grams. The DW-6900AKA-4 has the classic rounded shape with the triple-graph display, measuring slightly larger at 53.2 by 50 by 18.7 mm and weighing 67 grams.

Both watches offer the standard durability associated with the brand, including basic shock resistance and 200 meters of water resistance. They use a mineral glass display and run on a CR2016 battery, which Casio says should last about five years.

The feature set is identical across both models, including a 1/100-second stopwatch, a 24-hour countdown timer, multi-function alarms, a full auto-calendar, and a flash alert function that links the backlight to the alarm buzzer.

Both the DW-6900AKA-4 and DW-5600AKA-4 are available to purchase now through Casio’s website and standard retail channels.

In related news, Casio has recently unveiled a new translucent G-Shock inspired by 1990s streetwear aesthetics, and also introduced the vintage-style AQ230A-7DMQY watch with a stainless steel bracelet in the US market.

Casio has announced a new addition to its G-Shock lineup, partnering with the Seoul-based clothing brand thisisneverthat for a custom version of the standard DW-5600. The new model, officially named the DW-5600TNT-7, is scheduled to launch in July 2026. It takes the familiar DW-5600 square shape and updates it with clear materials and a few specific design adjustments.

Design Details

Casio used a translucent, clear resin for both the outer bezel and the watch band. The watch face features an inverted LCD, meaning the background is black and the numbers are light, which provides a high-contrast look against the clear resin.

The thisisneverthat logo appears in multiple locations, including the upper section of the dial above the display, the translucent strap keeper, and the stainless-steel case back.

The words PROTECTION and G-SHOCK, which are typically just molded or painted onto the top and bottom of the bezel, are coated in a phosphorescent finish on this model. This means the text itself glows in the dark, separate from the watch’s internal screen lighting.

Internally, the watch relies on the standard technology you would expect from the DW-5600 series. It measures 48.9 by 42.8 by 13.4 millimeters and weighs 52 grams. The screen is covered by mineral glass. It includes Casio’s standard shock resistance and is water-resistant up to 200 meters.

The daily feature set is straightforward. It includes a 1/100-second stopwatch, a 24-hour countdown timer, and a multi-function alarm. There is also a flash alert setting that blinks the white LED backlight when an alarm or timer goes off. For power, the watch uses a standard CR2016 coin-cell battery.

Casio estimates the battery life at about five years, meaning you will eventually need to open the case to swap it out, as this model does not include the company’s solar charging technology.

Pricing and Availability

The DW-5600TNT-7 is currently listed on Casio’s international site and will retail for ¥18,700 ($116) in Japan when it releases this July. It will ship in a custom box designed specifically for the collaboration.

In related news, Casio recently brought the retro-inspired AQ230A-7DMQY to the US with a stainless steel bracelet, while also launching the premium MTG-B4000B-1A G-Shock featuring a carbon fiber and stainless steel construction.

Casio has released the AQ230A-7DMQY in the United States. The watch, which is part of the company’s Vintage lineup, is priced at $59.95. While it is a new addition to the US market this month, this specific model has already been available for purchase in several international regions.

Design Details

The AQ230A-7DMQY is an analog-digital hybrid watch. It features a rectangular resin case that is chrome-plated, measuring 38.8 millimeters long, 29.8 millimeters wide, and 8.1 millimeters thick. It weighs 47 grams. Casio categorizes the design as unisex, and the relatively small dimensions make it suitable for a variety of wrist sizes.

The watch comes with a stainless steel band equipped with a self-adjustable clasp, which allows the wearer to change the band length between 140 and 205 millimeters without needing specialized tools or a trip to a jeweler.

The watch face uses a dual-display format. The upper portion contains a traditional analog layout with two hands to indicate the hour and minute. The lower section, positioned at the six o’clock mark, features a small digital LCD panel. This digital display handles the watch’s secondary functions, most notably a dual-time feature that lets users track a second time zone alongside their local time.

In addition to dual time, the digital panel provides access to a standard set of Casio features. This includes a 1/100-second stopwatch that measures elapsed time up to 59 minutes and 59.99 seconds. It also includes a daily alarm, an hourly time signal, and an auto-calendar.

For durability, the watch uses a resin glass crystal over the dial. It has a basic water resistance rating, meaning it can withstand minor splashes or rain, but it is not intended for swimming or showering. The watch is powered by a single SR920W battery, which provides an estimated three years of battery life before needing replacement.

In related news, Casio recently launched the MTG-B4000B-1A G-Shock, which pairs carbon fiber with stainless steel for a premium build, alongside three ocean-inspired timepieces with striking transparent blue designs.
