G-Shock GMA-S2100PR-4A limited Pink Ribbon edition to be released in October
September 16, 2026
Currently listed at Casio Japan and Europe for an October 2026 release (and expected to be released worldwide) is the G-Shock GMA-S2100PR-4A, another limited edition G-Shock watch supporting pink ribbon campaigns and breast cancer awareness. This 42.9 millimeter-wide women’s watch features a light pink bezel and band, with purple hands and index markings on the dial and a ribbon-shaped indicator. In Japan, 5% of the sales of this model (GMA-S2100PR-4AJR, ¥18,700) will be donated by Casio Computer Co., Ltd. to the certified NPO J.POSH. In Europe, the eco-friendly box is cobranded with Odysséa, a French non-profit group that organizes running and walking events for breast cancer awareness. The watch is marketed as the fourth Pink Ribbon edition G-Shock, but we’re counting it as the sixth when including the other two men’s models which are black with pink accents.
The European release includes a box supporting Odysséa.
