For months, US G-Shock fans watched Japan receive the most technically sophisticated square in the lineup’s history. Casio’s American reps offered a response that stung: no plans for a domestic release. That position has shifted. The resin GW-BX5600CBG-2 arrived at US retail in April 2026 at $250, and the stainless-steel GMWBZ5000 family, priced from $660 to $720 depending on finish, is now available through Casio’s US online store and select locations including the G-Shock SoHo Store in New York, per NotebookCheck.
What the New Display Actually Does
The Memory-in-Pixel LCD is the central upgrade, delivering sharper rendering and better outdoor legibility than the square format has seen before.
The core change is the Memory-in-Pixel LCD, a display technology that embeds memory directly into each pixel. According to Casio’s product documentation, it delivers “high-precision, high-contrast” rendering with a wide viewing angle and “outstanding readability even in bright outdoor spaces and direct sunlight,” which represents a meaningful improvement over the negative LCD on a GWM5610.
You can switch the main clock font between STANDARD and CLASSIC modes through the Casio Watches app. STANDARD offers a traditional 7-segment look; CLASSIC provides a more graphically detailed layout.
Timekeeping That Runs Itself
Multiband 6 and Bluetooth Smartphone Link work together to keep the watch accurate without any input from you.
Multiband 6 handles time accuracy automatically, pulling standard-time radio signals from six stations across Japan, North America (the WWVB transmitter in Fort Collins, Colorado), the UK, Germany, and China, syncing up to several times per day when in range. When you travel outside signal coverage, Bluetooth Smartphone Link steps in and pulls accurate time from your phone via the Casio Watches app.
The practical result is a watch that corrects itself across continents without you touching a button. Casio engineered the MIP panel so Tough Solar covers the full power load, including the display. There are no charging cables and none of the low-battery anxiety that comes with a smartwatch.
Models, Prices, and What to Know Before Buying
Two distinct product lines now cover the MIP square category in the US, one in resin and one in stainless steel.
The GW-BX5600CBG-2 carries the classic 5600 square silhouette in resin and retails at $250 through Casio US. That figure compares favorably to the roughly $245 plus tariffs and shipping that earlier Japan-only JF variants typically cost when imported, according to retailer pricing data.
The three GMWBZ5000 variants, the D-1, BD-1, and GD-9, swap resin for stainless steel and land between $660 and $720 per NotebookCheck. The technology stack is identical to the resin model; the build is premium and the price reflects it.
Japan Heartful Store’s editorial review calls the GW-BX5600 “the most technically advanced square G-SHOCK ever made,” framing that as a retailer opinion rather than a manufacturer specification. One caveat worth noting: MIP is new to the square G-Shock format, and long-term display durability under extreme conditions has not yet been established through extended field use.
What US Availability Actually Changes
Domestic availability removes the import barrier that kept many US buyers on the sidelines.
If you have been watching this category and waiting to avoid import fees and customs risk, that barrier is now gone for the core MIP square lineup. Both the GW-BX5600CBG-2 and the GMWBZ5000 series are purchasable directly through Casio’s US online store or in person at the G-Shock SoHo Store in New York. Note that certain Japan-market colorways and references remain import-only; US availability applies to the category broadly, not every individual variant. The domestic launch suggests Casio is treating MIP square models as a sustained US offering rather than a limited experiment.
