Casio has set a $110 US price for its 2026 Pink Ribbon G-Shock, the GMA-S2100PR-4A, with an October 1 launch for Breast Cancer Awareness Month. It’s the fourth watch in the annual initiative, this time using the smaller, octagonal GMA-S2100 design.

Alongside the release, G-Shock is donating $25,000 to the Breast Cancer Research Foundation in 2026. The contribution is fixed and doesn’t depend on watch sales. That US commitment is separate from the Japanese and European charity arrangements in our September look at the Pink Ribbon model.

The ribbon has a place on the dial

The case, band and dial are soft pink, with brighter magenta accents on the hands, indices and case markings. Look at the day indicator at 9 o’clock and you’ll see the ribbon itself: the little hand takes the shape of the breast cancer awareness symbol. It’s a small detail within an otherwise familiar analog-digital layout.

The GMA-S2100PR-4A’s case measures 46.2 mm from end to end, 42.9 mm across and 11.2 mm thick, and the watch weighs 41 grams. Casio specifies a wrist range of 140 to 205 mm for the band. Those are useful numbers to check if you like the 2100 shape but want to keep the size and weight down.

The construction still includes Carbon Core Guard, shock resistance, mineral glass and a 200-meter water-resistance rating. Key resin components in the bezel and band use bio-based material. Casio also supplies special packaging for the 2026 initiative, carrying the Pink Ribbon theme through to the box.

Familiar G-Shock functions

Two SR726W batteries power the watch, with an estimated life of three years, so there’s no daily charging routine to work around. The digital functions include world time across 31 time zones covering 48 cities plus UTC, five daily alarms, a stopwatch and a countdown timer of up to 24 hours.

When the analog hands obscure the screen, the hand-shift function moves them aside. Separate LEDs light the face and digital display, so illumination covers both parts of the dial.

US price and availability

The announced US price is $110. Casio’s October 1 rollout covers its online store, the G-Shock Soho Store and select retailers. You can find the model on Casio’s US product page; check with your chosen seller for current stock.
