35 years of ICERC Japan’s whale and dolphin conservation work are now wrapped into two translucent blue G-Shock watches: the Frogman GW-8202K-2 and the CasiOak GA-B2100KB-2A. Casio has officially unveiled its 2026 G-Shock x ICERC “Love The Sea and The Earth” collection, with both models scheduled to launch in early June, according to Notebookcheck.
The release pairs a higher-end ISO-rated Frogman at approximately $540 with a more accessible Bluetooth-equipped CasiOak at approximately $180. Both use skeleton-style blue designs tied to the ocean theme and ship with a cardboard box and cotton storage pouch.
“Love The Sea and The Earth” is the long-running banner for Casio’s annual ICERC Japan collaboration.
Casio launches 2026 G-Shock x ICERC skeleton blue Frogman and CasiOak models
The 2026 collection includes two watches, not a broad lineup: the GW-8202K-2 Frogman and the GA-B2100KB-2A CasiOak. That keeps the release tightly focused around two familiar G-Shock shapes with very different buyers in mind.
ICERC Japan is described in the source material as a nonprofit that has spent 35 years working to protect whales and dolphins. Casio’s annual summer partnership with the group has become one of G-Shock’s recurring conservation-linked releases, and this year’s edition uses the anniversary as the design anchor.
The timing is also clear. Both models are planned for early June, putting the collection into Casio’s summer release window rather than leaving it as a leak or teaser.
The two-model structure matters because Casio is not simply repainting one watch. It is applying the same marine-conservation theme to two separate G-Shock identities: the dive-focused Frogman and the thinner octagonal CasiOak.
For readers tracking Casio’s broader watch pricing outside this ICERC drop, MLXIO has separately covered the €49.90 Casio W-738H rollout across Europe, the £35 Casio MQ-24 steel model, the Japan-only G-LIDE surf watch, the G-Shock GravityMaster metal bezel, the $280 rainbow G-Shock, and Casio Edifice textured dials. Those are separate releases, but they show how wide Casio’s watch catalog runs compared with this themed G-Shock pair.
Skeleton blue design ties the new G-Shock watches to ocean conservation
Both watches use a semi-transparent blue visual language, but Casio applies it differently across the two cases. The Frogman gets a light blue bioplastic case and strap intended to evoke the surface of open water, while the CasiOak uses a strap that shifts from near-clear at the lugs to deeper blue near the buckle.
The Frogman is the more technical-looking piece. Its asymmetric case shape is a signature of the line and is designed for wrist movement underwater and over wetsuits. The titanium bezel is used to reduce weight while adding corrosion resistance.
The CasiOak takes the anniversary theme in a more everyday direction. Its dark dial gets azure accent text, and its mode hand is shaped like a whale. That is a small detail, but it makes the ICERC link visible without turning the watch into a full novelty design.
Two ocean-themed watches, two very different jobs
| Model | Platform | Approx. price | Main identity | Notable ICERC details |
|---|---|---|---|---|
| GW-8202K-2 Frogman | GW-8200 Frogman | $540 | Dive-focused G-Shock | Skeleton blue bioplastic, whale backlight animation, engraved caseback |
| GA-B2100KB-2A CasiOak | GA-B2100 CasiOak | $180 | Thinner octagonal everyday model | Whale-shaped mode hand, blue gradient strap, azure dial text |
The shared color treatment also places the release inside the established “Love The Sea and The Earth” series, where special branding and ocean-linked design cues do the storytelling. MLXIO analysis: the appeal here is less about adding new core G-Shock functions and more about packaging known platforms around a specific anniversary and cause.
That matters for G-Shock fans who follow seasonal or collaboration models. The source does not state that quantities are limited, so scarcity should not be assumed. But the Frogman and CasiOak bases give the release two built-in audiences before the ICERC theme even enters the equation.
Frogman GW-8202K-2 and CasiOak GA-B2100KB-2A pricing targets two G-Shock audiences
The GW-8202K-2 Frogman is the premium model in the pair at approximately $540, converted from 85,800 Japanese Yen. It is built on the GW-8200 Frogman platform, which the source describes as long associated with serious diving use.
Its spec sheet backs that positioning. The screwback case meets ISO 6425 200M water resistance standards, and the watch includes Tough Solar charging, Dive Time mode with underwater logging, tide graph, moon phase display, world time, stopwatch, timer and alarm.
Casio also adds themed touches that are specific to this release. The backlight shows a leaping whale animation, and the caseback carries an engraved “Love The Sea and The Earth” motif.
The GA-B2100KB-2A CasiOak lands much lower, at approximately $180, converted from 29,150 Japanese yen. It measures 48.5 × 45.4 × 11.9 mm and uses Carbon Core Guard construction.
The CasiOak still gets practical modern G-Shock features: Bluetooth and Tough Solar are both included. That makes it more than a colorway-only release, even though the anniversary design details are the headline.
MLXIO analysis: launching these two together gives Casio a clean two-step collection. The Frogman carries the specialist dive-watch weight, while the CasiOak brings the same ICERC anniversary theme to buyers who want the look and story at a lower price.
Early June release will test demand for Casio’s 35th anniversary ICERC editions
The next practical questions are regional availability, retailer listings and final local pricing. The source gives Japanese yen-based conversions, but it does not confirm every market where the watches will appear.
Buyers should also watch whether Casio or authorized dealers describe either model as limited. The source says both watches are part of the 2026 ICERC collection and are scheduled for early June, but it does not state production numbers.
Official Casio product pages, G-Shock channels and authorized retailers are the most relevant places to monitor as the release window opens. That is especially true for the Frogman, where the higher price, ISO dive credentials and anniversary branding may concentrate attention among G-Shock collectors.
The main scenario to watch: whether Casio treats this as a standard seasonal conservation release or whether market-specific listings point to tighter availability. For now, the confirmed story is simple and specific — two skeleton blue G-Shocks, one $540 Frogman and one $180 CasiOak, tied to ICERC Japan’s 35th anniversary and due in early June.
Key Takeaways
- Casio is marking ICERC Japan’s 35 years of whale and dolphin conservation with two themed G-Shock releases.
- The collection targets different buyers by pairing a premium Frogman with a lower-priced Bluetooth CasiOak.
- The early June launch gives collectors a confirmed window for a limited conservation-linked summer release.
