Casio has unveiled a fresh collection of G-Shock watches in the US, with an emphasis on compact sizes and a distinctive glass treatment. The new lineup consists of four hybrid analog-digital timepieces based on the company’s well-known octagonal design, often affectionately called the CasiOak by fans. What sets these models apart is the use of polarized glass, which alters its color depending on the angle of your wrist.
Design Details and Pricing
To achieve this effect, Casio employs a polarized vapor deposition process on the mineral glass. This technique results in a colorful gradient on the watch face that shifts as it interacts with light. While it’s a visually appealing feature, Casio acknowledges a practical downside: the reflections and color changes can make the dial harder to read in certain lighting conditions. This detail is important to consider if you prioritize functionality over style.
The release is divided into two distinct styles, both tailored for smaller wrists. The first pair, the GMA-P2100SR-7A and GMA-P2100SR-1A, are priced at $135. These models utilize translucent resin for both the case and the band, offering a clear and casual aesthetic. Being entirely made of resin, they are notably lightweight, weighing just 40 grams.

The second pair, the GM-S2110SR-1A and GM-S2110SR-7A, come with a higher price tag of $210. These models replace the resin bezel with stainless steel, adding a bit more weight (56 grams) and giving the watch a more traditional metallic look. Casio also incorporates bio-based resin for the bands on these metal models, a material the company has been using increasingly to reduce its environmental impact.

Beyond the new glass and compact size, these watches function like standard G-Shock models. They include the usual features such as shock resistance, 200 meters of water resistance, world time for 31 time zones, a stopwatch, a countdown timer, and daily alarms. They also have a built-in LED backlight to assist with visibility in the dark. All four models are powered by a standard CR1025 battery, which Casio claims will last approximately three years before requiring replacement.
All four models are currently available for purchase. If you have a smaller wrist or prefer a more compact design, these are a practical choice, provided you’re comfortable with the color-shifting glass occasionally affecting readability.
