A February 2018 release in Taiwan and a March release elsewhere, the G-Shock GA-110CR Coral Reef Color Series is a collaboration with nonprofit environmental conversation group Aqua Planet meant to bring awareness to global warming and its effect on the marine environment. The semi-translucent colors in this series are inspired by Aqua Planet’s commitment to the ecological conservation of coral reefs. Representing the ocean is the blue GA-110CR-2A while the red GA-110CR-4A and clear white GA-110CR-7A represent living coral. The pointer at the nine o’clock position is inspired by the color pattern of a clownfish.
Update: G-Shock Japan is releasing the GA-110CR-2AJF, GA-110CR-4AJF, and GA-110CR-7AJF in March 2018 with a list price of ¥16,000 JPY each.
It looks like North America is only getting the GA110CR-7A and BA110CR-7A.
Casio is also releasing a matching Baby-G series which includes the BA-110CR-2A, BA-110CR-4A, and BA-110CR-7A.
