Casio is set to introduce two new models to its popular G-Shock Full Metal collection this October: the GM-B2100SD-1A and GMC-B2100ZE-1A.
G-SHOCK GM-B2100SD-1A features
The GM-B2100SD-1A, a refined version of the 2022 GM-B2100D-1A, offers improved readability with a darker grey background and silver watch hands and hour markers. This seemingly minor design tweak could make a significant difference in user experience, especially for those who rely on their watches for quick and easy time checks in a variety of lighting conditions.


This model features a hybrid analog and digital display, Bluetooth connectivity, and solar charging. The Bluetooth functionality allows the watch to sync with smartphones for automatic time adjustments, reminders, and a phone finder tool, making it more than just a standard timepiece. Casio’s solar charging system provides up to seven months of battery life, ensuring the watch remains functional for extended periods without frequent charging.
Pricing & availability
The GM-B2100SD-1A is currently available for pre-order in Japan at JP¥84,700 (~$572). Global availability and pricing have not yet been confirmed.
G-SHOCK GMC-B2100ZE-1A features
In celebration of Casio’s 50th anniversary, the GMC-B2100ZE-1A boasts a black ion-plated stainless steel bezel with gold accents and a gold ion-plated link in the stainless steel band. This unique design combination blends sophistication with the ruggedness for which G-Shock is known.

While the GMC-B2100ZE-1A is similar in features to other GMC-B2100 models, such as Bluetooth connectivity and solar charging, its aesthetic sets it apart. Apart from the gold accents, the model will also benefit from Casio’s usual smart features, including automatic time adjustments and phone control via the Casio Watches app.
Pricing & availability
The GMC-B2100ZE-1A is expected to be priced significantly higher than the GM-B2100SD-1A, with early rumors suggesting a US retail price of around $930. However, the official release date and pricing outside of Japan have yet to be confirmed.
