DW-5600 (Square)

The Casio DW-5600 family carries the original G-Shock idea in its most recognizable shape: a squared-off digital display sheltered inside a shock-resistant case. But “square” describes a lineage, not a single specification, and beneath that familiar outline sit different case constructions, lighting systems, and approaches to keeping time.

The DW-5600C, introduced in 1987, used a metal inner case and screw-in back; the DW-5600E, arriving in 1996, moved to resin construction with a steel back secured by four screws and electroluminescent illumination. Those changes make the two generations meaningfully different despite their shared silhouette. Later battery-powered versions retain the straightforward stopwatch, countdown timer, and alarm toolkit, while illumination and module details vary across references.

The solar-powered, radio-synchronized GW-5600 branch adds another layer of convenience without abandoning the square format. The widely documented GW-M5610 combines Tough Solar with Multiband 6 reception. Meanwhile, the DWE-5600 takes a different route, using Carbon Core Guard construction and interchangeable bezels and bands: the familiar face becomes a platform for changing its outer shell.
