Description
G-SHOCK 6900 SERIES GW-6905K-7AJR ICERC Japan Collaboration Model 2025
The G-SHOCK GW-6905K-7AJR is a 2025 collaboration model created with ICERC Japan under the “Love The Sea And The Earth” theme. Based on the digital 6900 SERIES, this Japanese Domestic Market watch combines a white and deep-blue color scheme with humpback-whale details, Tough Solar power and MULTIBAND 6 radio-controlled timekeeping.
Humpback Whale-Inspired Design
The model takes inspiration from the humpback whale and its distinctive long pectoral fins. Its contrasting white and deep-blue colors reflect the whale’s two-tone body, while the deep blue evokes the open ocean through which humpback whales migrate.
Humpback-whale silhouettes appear on the front light button, band keeper and digital display when the LED backlight is illuminated. The face also features a pattern inspired by the striped underside of the whale. An ICERC Japan logo is printed on the band, and the case back is engraved with the “Love The Sea And The Earth” symbol.
ICERC Japan Collaboration
G-SHOCK and BABY-G have supported environmental organizations through collaborative watches since the late 1990s. This model supports ICERC Japan, an organization that communicates the importance of the natural environment through educational activities focused on dolphins, whales and the oceans they inhabit.
Biomass Plastic Resin Construction
The shock-resistant resin construction is designed for everyday durability. Biomass plastic is used for the principal resin components of the bezel and band, supporting the environmental concept behind the collaboration. The case measures 53.2 × 50 × 17.7 mm, weighs 71 g and fits wrists measuring approximately 145–205 mm.
Tough Solar and MULTIBAND 6
Tough Solar technology converts light into electrical power, while MULTIBAND 6 receives compatible standard time signals in Japan, North America, Europe and China. When radio reception is unavailable, the watch operates with an accuracy of approximately ±15 seconds per month.
From a full charge without further light exposure, the watch operates for approximately 10 months under normal use or approximately 26 months with power saving activated.
Practical Digital Functions
The module includes world time for 48 cities, a 24-hour stopwatch, a 24-hour countdown timer, five daily alarms and a full auto-calendar. A white LED Super Illuminator provides enhanced visibility and reveals the special whale silhouette incorporated into the display.
