Casio Computer Co., Ltd. has announced the new G-SHOCK GMA-S2100PR-4AJR. The 4th collection supporting Pink Ribbon activities is scheduled to launch in October 2026.
The GMA-S2100PR-4AJR is a new addition to the GMA-S2100 series, featuring a compact, slim design based on the series’ octagonal form. Designed for everyday wear, it will be released to coincide with Pink Ribbon Month in October.
5% of the model’s sales in Japan will be donated to the certified NPO J.POSH to support Pink Ribbon activities. The design is finished entirely in pastel pink, with a Pink Ribbon motif placed on the small hand at the 9 o’clock position.
Functions include World Time, which can display the time in 48 cities across 31 time zones plus UTC, a 1/100-second stopwatch and a 24-hour timer. The watch also features Neobrite luminous coating, a Super Illuminator and 20-bar water resistance.
Weighing just 41g, the watch combines everyday legibility and durability with a shock-resistant structure in a lightweight special model. It is scheduled to launch in October 2026, with part of the sales proceeds allocated to the donation.
