Join the fight against breast cancer with the all-pink GMA-S145PK, the third G-SHOCK watch created in support of pink ribbon campaigns. Based on the GMA-S140, it features the same iconic pink color used in the previous two editions. The monochromatic design adds a pop of color to your simple, everyday looks. 

The GMA-S145PK 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.
