Join the fight against breast cancer with the all-pink GMA-P2110B, the fourth G-SHOCK watch created in support of pink ribbon campaigns. Based on the GMA-S2100 line, it features a soft pastel pink colour scheme with a pink ribbon-shaped indicator on the inset dial at the 9 o’clock position. The design combines simple, everyday beauty with thoughtful details that share your commitment to raising awareness.
The GMA-P2110B reflects 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 held back by illness.
To join G-SHOCK and support the movement, keep an eye out for fundraising campaigns and events around the world during “Pink October,” breast cancer awareness month, when the pink ribbon is out in full force.
What is the pink ribbon movement?
The pink ribbon is a universal symbol of various efforts involved with breast cancer. Medical organisations and support groups use it to promote accurate information about breast cancer, raise awareness of the importance of regular checkups, and support patients. October is recognised internationally as Breast Cancer Awareness Month, and the pink ribbon movement is especially active during this month with events and campaigns.
* Key resin components used in the bezel and band are made with bio-based resin. Produced using renewable organic resources, this material is expected to help reduce environmental impact.
