Casio has given two of its most familiar G-Shock shapes a far more distinctive identity, and the result is a release that looks built to stand out before it is even worn. The DW-6900AKA-4 and DW-5600AKA-4 trade on a strong Japanese lantern theme, using color and lighting to turn a classic digital watch into something more collectible.
The concept draws from aka-chochin, the red paper lanterns commonly associated with Japanese restaurants and street scenes. Rather than changing the core platform, Casio focused on visual cues that make the watches feel curated, with the design doing most of the talking.
Lantern-inspired design details
Red dominates the case and strap on both models, while black buttons and a black band loop create a sharp contrast. Casio says the darker accents are meant to recall the lacquered support often seen beneath traditional paper lanterns.
The theme continues on the dial, where a kanji character meaning shock resistance is used as part of the design language. Even the backlight follows the concept, shifting away from the usual white glow in favor of a warm orange LED meant to resemble a lantern shining in the dark.
Casio also added a special engraving on the case back and ships the watches in themed packaging. The finishing touches reinforce the idea that these are not routine color updates, but deliberately framed special editions.
Two familiar G-Shock foundations
Under the themed exterior, the two watches stay close to the formulas that made the 5600 and 6900 lines recognizable. The DW-5600AKA-4 keeps the square profile that defines the 5600 series, while the DW-6900AKA-4 uses the rounded 6900 shape with its triple-graph display.
The DW-5600AKA-4 measures 48.9 x 42.8 x 13.4 mm and weighs 53 grams. The DW-6900AKA-4 is larger at 53.2 x 50 x 18.7 mm and comes in at 67 grams, giving it a more substantial presence on the wrist.
Casio lists both models at $190 each through its official site and standard retail channels in the United States. The two watches first debuted in Japan in April before reaching the U.S. market.
| Model | Size | Weight | Style |
|---|---|---|---|
| DW-5600AKA-4 | 48.9 x 42.8 x 13.4 mm | 53 g | Square 5600 case |
| DW-6900AKA-4 | 53.2 x 50 x 18.7 mm | 67 g | Rounded 6900 case with triple-graph display |
Core G-Shock functions remain intact
Casio did not change the underlying feature set, which means both watches still offer the toughness expected from the brand. Each model includes shock resistance and water resistance up to 200 meters, along with mineral glass protecting the display.
Power comes from a CR2016 battery, which Casio says should last about five years. The watches also include a 1/100-second stopwatch, a 24-hour countdown timer, a multi-function alarm, a full auto calendar, and flash alert.
Flash alert links the alarm with the backlight, adding a visual signal to the usual audio alert. It is a small detail, but it fits the practical character that has long defined the standard digital G-Shock experience.
A release aimed at design-focused buyers
The strength of this pair lies less in technical novelty and more in presentation. Casio has used bio-based resin for the case and band, then layered on visual details that make the watches feel tied to a specific cultural reference.
That approach gives the release a clear identity in a market crowded with special editions and collaborations. For collectors, the orange LED, kanji detail, engraved case back, and themed packaging create a stronger draw than a simple recolor would.
For everyday buyers, the choice comes down to shape as much as style. The DW-5600AKA-4 offers the cleaner square profile, while the DW-6900AKA-4 delivers a thicker, more prominent look with the same lantern-inspired treatment.
Both models are now available in the United States through Casio’s official site and regular retail channels. They keep the familiar G-Shock formula intact, but wrap it in a design language that makes the watches feel far more intentional than a standard seasonal update.
