G-SHOCK GW-6905K — ICERC Japan Collaboration, Humpback Whale
ICERC Japan Collaboration Model 2025 / DIGITAL / 6900 Series / Released August 2025
The GW-6905K is a collaboration model with ICERC Japan, an organization working under the theme "Love The Sea And The Earth" to share the wonder of nature through dolphins and whales. The 2025 model takes the humpback whale — known for its large pectoral fins — as its design motif, expressing the whale's two-tone coloring through a high-contrast color scheme, with deep blue representing the open ocean where humpback whales migrate. The "ICERC Japan" logo is printed on the band, and the "Love The Sea And The Earth" symbol mark is engraved on the case back. The main resin parts of the bezel and band use biomass plastic out of consideration for the environment, and the packaging uses recycled materials.
Tough Solar and Multi-Band 6 radio time correction keep the watch running accurately with minimal upkeep, backed by a full auto LED backlight for after-dark visibility.
