Casio G-Shock “Sushi Gunkan Maki” DW-6900SSH-1JR — JDM Special Edition (Made in Japan)

A gastronomic concept design based on the iconic round “Three-Eyed Monster” case, Made in Japan. The Casio G-Shock DW-6900SSH-1JR is a special edition exclusive to the Japanese domestic market (JDM - Japanese Domestic Market) and is manufactured entirely in Japan. Drawing on the classic DW-6900’s distinctive circular silhouette, this model pays homage to the Ikura Gunkan Maki (the traditional sushi roll wrapped in nori seaweed and topped with salmon roe), fusing Japanese pop culture with G-Shock’s extreme durability.

Design Highlights and Concept

• Three-Dimensional “Ikura Gunkan Maki” Aesthetic: The black bezel and the outer surface of the strap represent the strip of nori seaweed that wraps around the sushi, while the white inner surface of the strap symbolizes the rice base (shari). The translucent central dial graphically reproduces the shine and orange texture of salmon roe (ikura).
• Manufactured in Japan (Made in Japan): Produced at Casio’s Japanese factories, the stainless steel case back features a special engraving of a cup of hot green tea (Agari), a traditional symbol marking the end of a meal at a sushi bar.
• Special Bento Box Packaging (Sabi-nuki Detail): Presented in a conceptual case that mimics a wooden bento lunchbox. True to Japanese culinary tradition—where salmon roe gunkan is typically served without wasabi so as not to alter its flavor—removing the watch from the inner holder reveals an illustration of “clean rice” (sabi-nuki / without wasabi).
• Updated Module with Super Illuminator LED: Incorporates the technical upgrade of the 6900 series with high-power white LED backlighting, a front button for direct access to the light, and an extended battery life of 5 years.
