This month finds Casio G-Shock launching the first limited-edition model of the GWF-D1000 Frogman. Part of the "Love the Sea and the Earth" collection, celebrating the 25th anniversary of the I.C.E.R.C. (International Cetacean Education and Research Centre), an organization dedicated to whale and dolphin research, the GWF-D1000K-7JR is limited to just 1,500 units. Its bezel is white, printed with blue text that matches the same shade used on the band, and it has ISO standard 200m waterproof performance. The watch joins the already launched GWX-8903K-7JR and Baby-G BGR-3006K-7JR, which hit G-Shock retailers in Japan in late May.
