Casio’s square G-Shock just got the upgrade fans have been asking for. The new GW-BX5600-1JF and GW-BX5600-1A1JF pair the iconic 5600 silhouette with a high-contrast MIP LCD, Tough Solar power, Bluetooth connectivity, and Multi Band 6 atomic timekeeping—without losing the tank-like durability that made the series famous. Both models are listed at ¥30,800 (around $200) and are slated to ship in November 2025, with pre-orders already open in Japan.

It’s a modern screen in a time-tested form factor.
