G-Shock is known for its many color variations, but during the early years, black was the only option. The first color G-Shock was the yellow DW-5600C-9BV, released overseas in 1987. (1987 was also the debut of the DW-5600 series.) The blue DW-5600B-2V and green DW-5600B-3V came in 1991, and the yellow model was revived as the limited edition DW-5600C-9B in 1992, becoming an iconic square color over the years.
Casio is now releasing four watches that pay tribute to the original color square G-Shocks: the blue DW-5600RB-2, green DW-5600RB-3, yellow DW-5600REC-9, and the limited edition Carbon Core Guard DWE-5600R-9 box set.
The present-day DW-5600 watches have a resin inner case and stainless steel backplate, unlike the full stainless steel screw-back case of the originals, resulting in a lighter weight for the new models. The limited DWE-5600R-9 box set includes a DWE-5600 watch (featuring a carbon fiber reinforced inner case) and three interchangeable bezels and bands in yellow, black, and red. (These bands are also compatible with the DW-5600 series, but the bezels are a screwless design that depend on the latch points of the DWE-5600 case.) Like the original DW-5600C-9BV, the yellow DW-5600REC and DWE-5600R have a black band keeper. The DW5600RB models have a gold-tinted LCD display, like the original DW-5600B watches.
In Japan, the DW-5600RB-2JF, DW-5600RB-3JF, and DWE-5600R-9JR box set will be released in October 2021. The yellow DW-5600REC-9JF will be released in November 2021. All four models are also expected to be released worldwide with the following retail prices in the U.S.: DW5600RB-2 ($99), DW5600RB-3 ($99), DW5600REC-9 ($110), DWE5600R-9 ($210).
Update: The DW-5600REC-9 box set was announced for October 2021 in Asia (excluding Japan, where it is expected in November).
