Casio’s G-Shock continues to be one of the most beloved watch families for its durability, design diversity, and collector appeal. As we look toward 2026, several fresh models and collaborations are already being teased or revealed in fresh leaks, ranging from full-metal premium timepieces to fun limited editions tied to global brands. So if you’re looking forward to Casio’s new 2026 watch lineup, here are a few upcoming models to look out for.
1. GMW-BZ5000 Rainbow Edition
Casio is rumored to be working on a premium new watch that could get a multicolored hue to its metallic shine. Following the launch of the GMW-BZ5000, the popular watch maker is reportedly preparing to release a new GMW-BZ5000RC-1 model, which could be a rainbow ion plated version. This limited edition will add a bold gradient finish to the already modern classic silhouette of the 5000 series, blending premium materials with eye-catching style.
It will also bring a full metal case with premium features that likely include Tough Solar power, Bluetooth connectivity, and Multi-Band 6 radio timekeeping. The original GMW-BZ5000D came with a black and gold ion plated variant recently, so the new limited edition model adds a bold new finish, which is likely aimed at collectors and enthusiasts.
2. G-Shock x Coca-Cola CasiOak
For collectors and fans of quirky collaborations, one of Casio’s 2026 lineup might be the perfect fit. Casio and Coca-Cola previously teamed up on limited editions, and leaked info suggests a follow-up model. Reportedly, the next model in the series is the GA-2100CC-3A with design cues inspired by Coca-Cola’s classic branding and the iconic green glass bottle aesthetic for the popular CasiOak watch. These kinds of collaboration models generally focus on eye-catching design details, co-branded packaging, and collectible appeal rather than major technical upgrades. But this helps it stand out from a traditional watch.
3. Japanese shochu meets Casio G-Shock
The Coca-Cola edition CasiOak isn’t the only collaboration in the works, as a recent leak hints at another partnership for a special edition G-Shock watch. Casio is apparently joining hands with Japanese shochu label iichiko Super, which is built on the GM-5600U square. Based on the leaked images, there is a stainless steel bezel, a negative digital display and a custom strap with a red stripe and blue tip with iichiko Super’s bottle colors. The strap even carries the Japanese spirit makers’ logo. Expect limited quantities and a distinct design that celebrates both brands’ identities.
4. Speed meets precision with Casio x Honda
While not strictly G-Shock, the Edifice x Honda collaboration (ECB-2300HR-1AJR) is part of Casio’s broader 2026 wristwear lineup and worth mentioning for its premium build and racing-inspired design. Officially listed in Japan with a March 2026 release and a price tag around ¥66,000 (~$426), this limited edition draws on the story of Honda’s historic motorsport achievements. Edifice models blend precise chronograph functionality with bold aesthetic nods to automotive heritage, making them a strong choice for fans of performance-inspired timepieces.
