G-Shock is releasing a new “RB” series featuring its signature brand colors of red, black, and white. The collection includes three Tough Solar/Multi-Band 6 models and one battery-powered GA-110. As we’ve seen with some other recent series, although the four watches share the same color scheme, some individual elements are unique to certain models. For example, the AWG-M100SRB-4A is the only one of the four that has a jelly-style translucent red case and it also has a glossy black band. The GA-110RB-1A has a glossy black bezel and glossy red band. The GAW-100RB-1A has a red aluminum bezel, matte black case, and matte red band. The GW-M5610RB-4 has a matte red bezel and matte black band. All four watches have reverse LCD displays.
The AWG-M100SRB-4AJF (list price 25,000 JPY), GA-110RB-1AJF (16,000 JPY), GAW-100RB-1AJF (25,000 JPY), and GW-M5610RB-4JF (20,000 JPY) are May 2019 releases in Japan. All four models will also be released in other Asian markets, with the GAS-100RB-1A replacing the GAW-100RB-1AJF.
Update: The GWM5610RB-4 was released in the U.S. with a list price of $140 USD.

Color me surprised. I thought Casio had switched all their new solar square models to that new bluetooth module. As a bluetooth non-fan, I’m pleasantly surprised.
