G-SHOCK Pink Ribbon 2026 | October 2026

Join G-SHOCK in supporting breast cancer awareness and research!

This G-SHOCK watch embodies the Casio commitment to pink ribbon campaigns, which raise awareness of the importance of early detection, diagnosis and treatment of breast cancer. G-SHOCK and Pink Ribbon are natural allies, sharing a dedication to building a world where everyone can be healthy, is free to be themselves, and never misses out due to illness.

To join G-SHOCK and participate in the movement, keep an eye out for fundraising campaigns and events around the world throughout “Pink October,” which is Breast Cancer Awareness Month, when the pink ribbon is out in full force.

In 2026, Casio will donate 5% of the proceeds from the sale of this watch in Japan to J.POSH.
