Casio’s next square icon is almost here. The G-Shock GW-BX5600 series has leaked with a ¥30,800 price tag in Japan (about $207), positioning it as a major step up for fans of the classic 5600 silhouette.
The headline change is the move to a memory-in-pixel (MIP) display, replacing the older STN LCD used on previous 5600 models. Expect crisper contrast, cleaner text, and far better legibility from wider angles—exactly what you want on a daily-wear digital. The watch also adds Bluetooth for smartphone syncing, joining radio-controlled timekeeping as part of the feature set that defines the Origin line. Reports point to a new module (3578) underpinning these updates while preserving the timeless square design and rugged resin build.
Two versions are shown so far:
– GW-BX5600-1 with a positive (light-on-dark) display
– GW-BX5600-1A1 with a negative (dark-on-light) display
With these upgrades, the GW-BX5600 sits roughly 20% higher than the GW-M5610U, which retails for around ¥24,200 (approximately $165). Given the improved screen technology, added Bluetooth functionality, and rising material costs, that premium should make sense to long-time G-Shock collectors and new buyers alike.
Key takeaways for shoppers:
– Price in Japan: ¥30,800 (about $207)
– Display: MIP for sharper contrast and better viewing angles
– Connectivity: Bluetooth smartphone sync plus radio-controlled timekeeping
– Design: Classic square case, tough resin construction
– Variants: Positive display (GW-BX5600-1) and negative display (GW-BX5600-1A1)
– Module: Reported as 3578
– Positioning: A significant modern refresh of the beloved 5600 series
A Japanese release is expected first, and if past patterns hold, a global rollout should follow. If you’ve been waiting for a true modernized square G-Shock without losing the heritage look, this could be the update worth grabbing as soon as it drops.
