Fourth annual special edition lands October 1 with a $25,000 gift to BCRF and the researchers turning today’s science into tomorrow’s treatments 

JERSEY CITY, N.J., Sept. 30, 2026 /PRNewswire/ — Casio America, Inc. today announced the Pink Ribbon Model GMAS2100PR, the fourth special-edition G-SHOCK timepiece underscoring the company’s commitment to the Breast Cancer Research Foundation (BCRF). Launching for Breast Cancer Awareness Month, the GMAS2100PR brings the Pink Ribbon initiative to the GMAS2100, the slim, octagonal analog-digital design that has become one of G-SHOCK’s most recognizable silhouettes. 

This year, G-SHOCK is donating $25,000, regardless of sales, to BCRF, the largest private funder of breast cancer research in the world. The donation supports BCRF’s 2026 campaign, “Today’s research. Tomorrow’s cures.,” which spotlights the work happening right now in labs and clinical trials that become the treatments, earlier detection, and breakthroughs of the future. 

“Every G-SHOCK is built to keep going, and that is what breast cancer research needs from all of us: steady, sustained support,”saidShermeen Greenmun, VP of Timepiece at Casio. “The GMAS2100PR is a way for people to wear that commitment every day, and our $25,000 donation to BCRF goes directly toward accelerating the science that changes what tomorrow looks like.” 

Design
The GMAS2100PR features a soft pink resin case and band with vivid magenta accents on the hands, indices, and case markings. A pink ribbon sits on the dial as a quiet, permanent reminder of the cause. The watch ships in exclusive packaging created for the 2026 initiative. Built on G-SHOCK’s Carbon Core Guard structure, the GMAS2100PR pairs a compact, wearable profile with the shock resistance the brand is known for, making it an everyday watch that carries a purpose.
