Choose a DW-5600 if you want a classic square G-Shock with a simpler feature set; choose a GW-M5610U if you want Tough Solar and Multiband 6; and consider the GW-5000U if its metal case and screw back are priorities. The 5600/5000 name covers multiple feature tiers, so confirm the exact reference and suffix before buying.
How to choose a G-Shock square
Start with the features you will actually use: how the watch is powered, how it corrects time, and what case construction you prefer. Casio’s 5600/5000 series guide includes basic, solar-powered, radio-controlled, and Bluetooth-equipped squares. Those features are not shared by every model in the family.

- Choose a DW-5600 family model for the familiar square design and a straightforward digital watch. Casio identifies the GW-M5610 bezel as based on the DW-5600 series, but check the chosen DW-5600 reference for its specific functions.
- Choose the GW-M5610U if Tough Solar and Multiband 6 are the draw. Casio’s European GW-M5610U-1 page lists both and connects its design to the 1983 DW-5000C.
- Consider the GW-5000U if you specifically want a solid metal case and screw back. Casio also lists Tough Solar and Multiband 6 for this model; those construction details are distinguishing features, not a universal reason to prefer it.
- Consider a Bluetooth square only if smartphone time correction and related phone functions matter to you. Casio describes Bluetooth-equipped versions in its series guide, but the feature is model-specific.
What the feature differences mean day to day
Power: conventional battery or Tough Solar
Casio describes Tough Solar as converting light into power for the watch’s functions. If you want solar charging, verify that the precise reference you are considering lists Tough Solar; the broad square-family name alone does not establish it. The cited product information does not provide a comparative charging or battery-life test.
Time correction: manual, radio, or Bluetooth
Multiband 6 receives time signals from stations in Japan, the United States, the UK, Germany, and China, according to Casio’s US GW-M5610-1 product page and series guide. Whether radio correction is useful depends on your location and reception. If you are outside reliable signal coverage, do not treat the radio feature as a guarantee of automatic correction. Bluetooth time correction is another model-specific option; check the listing for the exact reference.

Construction: resin square or metal case
The GW-5000U stands apart from the resin-square choice with a solid metal case and screw back, alongside a soft urethane band, as described on Casio’s GW-5000U collection page. Choose it for those materials and construction if they matter to you, rather than assuming every buyer will prefer them.

Check the exact model before buying
- Find the full reference number, including any suffix, on the product listing—not just “G-Shock square” or “5600.”
- Open the matching Casio product page for your region and confirm the functions you want, especially solar charging, Multiband 6, and Bluetooth.
- For Multiband 6, consider whether one of the supported time-signal stations is relevant to your location and whether you can receive its signal.
- Compare the construction details if you are deciding between a resin square and the GW-5000U’s metal case and screw back.
- Check local stock and the listing’s exact reference. Casio’s cited GW-M5610 pages are regional US and European pages, and features or suffixes can vary by market.
Casio’s 5000/5600 Origin history provides background on the series’ heritage. For a purchase decision, however, the exact model page is the better place to confirm current features.
