Casio has introduced a new limited-edition G-Shock watch, the GMA-S2100PR-4AER, to mark Breast Cancer Awareness Month this October.
The model is based on the analog-digital GMA-S2100 series and features a monochromatic pink colorway.
Design and Features
The watch showcases various shades of pastel pink across the case, band, and dial.
At the 9 o'clock position, the inset dial has been modified with a pink ribbon motif, the symbol for breast cancer awareness.
Hardware-wise, the GMA-S2100PR-4AER retains the standard specifications of the S2100 lineup.
It has a carbon fiber-reinforced case with Casio's Carbon Core Guard structure, and both the bezel and band are made from bio-based resin.
The watch measures 46.2 x 42.9 x 11.2 mm and weighs 41 grams, placing it on the more compact end of the G-Shock catalog.
It includes shock resistance and 200-meter water resistance.
Internal features include world time covering 31 time zones, a 1/100-second stopwatch, a 24-hour countdown timer, and five daily alarms.
A double LED system illuminates the display, and the watch runs on two SR726W batteries with an estimated three-year lifespan.
Partnership and Availability
Casio is launching this model in partnership with Odyssea, a French non-profit focused on breast cancer prevention, research, and patient support.
Alongside a financial donation, Casio is sponsoring charity race entries for Odyssea events in Paris and La Réunion.
The GMA-S2100PR-4AER will be available starting in October 2026.
In Europe, it will retail for €99.90 through select retailers, the Casio web store, and the Odyssea online store.
Casio has also listed the watch in the US, though official stateside pricing has not yet been announced.
