Casio officially launches new unique skeleton blue G-Shock Frogman and CasiOak watches

Every summer, Casio and ICERC Japan, which is a nonprofit that has spent 35 years working to protect whales and dolphins, release a joint G-Shock collection under the "Love The Sea and The Earth" banner. This year's release is one of the more unique ones in recent memory. Two models, which were leaked previously, make up the 2026 collection, with a release planned for early June.
GW-8202K-2
The higher-end piece is built on the GW-8200 Frogman platform, which has been long associated with serious diving use. The semi-transparent light blue bioplastic case and strap is meant to depict the surface of open water — and the effect does work. The titanium bezel keeps weight down while being corrosion-resistant. The asymmetric case shape (a Frogman signature) is designed specifically for wrist movement underwater and over wetsuits. The screwback case meets ISO 6425 200M water resistance standards.
Feature-wise, the GW-8202K-2 packs Tough Solar charging, Dive Time mode with underwater logging, tide graph, moon phase display, and the full standard G-Shock suite of world time, stopwatch, timer, and alarm. The backlight triggers a leaping whale animation on the display. The caseback has an engraved "Love The Sea and The Earth" motif. Price is approximately $540 (converted from 85,800 Japanese Yen).
GA-B2100KB-2A
The more accessible piece is based on the GA-B2100 CasiOak, measuring 48.5 × 45.4 × 11.9 mm with Carbon Core Guard construction. Its mode hand is shaped like a whale, azure accent text runs across the dark dial, and the strap transitions from near-clear at the lugs to a deeper blue at the buckle end. Bluetooth and Tough Solar are both present. Price is approximately $180 (converted from 29,150 Japanese yen).
Both watches ship with a cardboard box and a cotton storage pouch.
