CASIO

G-SHOCK is marking the start of Breast Cancer Awareness Month with a new watch made in support of Pink Ribbon Campaigns. The all-pink GMA-S2100PR-4A is the fourth G-SHOCK watch created for the cause. It goes on sale today, 1 October 2026, the first day of Pink October.

The Watch

The GMA-S2100PR-4A is based on the GMA-S2100 line, a compact, downsized take on the popular GA-2100 series. It comes in a soft pastel pink colour scheme, and the details carry the message. A pink ribbon-shaped indicator sits on the inset dial at the 9 o’clock position, a quiet show of support for those fighting breast cancer.

The watch also arrives in special all-pink packaging, which extends the support for breast cancer awareness and research.

Built Tough

Despite the soft palette, the watch keeps G-SHOCK’s toughness. It is shock-resistant with a Carbon Core Guard structure and offers 200-meter water resistance. It also has a 1/100-second stopwatch and 31 time zones covering 48 cities plus Coordinated Universal Time, with daylight saving on or off. The case measures 46.2 × 42.9 × 11.2 mm (L x W x H), and the watch weighs just 41g.

Why Pink Ribbon?

The release reflects CASIO’s commitment to Pink Ribbon campaigns, which promote the importance of early detection, diagnosis and treatment of breast cancer. G-SHOCK and the Pink Ribbon movement share a dedication to a world where everyone can be healthy, is free to be themselves, and never misses out because of illness.
