TOKYO, JAPAN — In a vibrant move blending street style with robust engineering, Casio has just unveiled three eye-catching additions to its iconic G-Shock lineup. The new GA-2100K series, launching in Japan, features a daring translucent design inspired by the dynamic atmosphere of music festivals and urban nightlife. Launched alongside the sophisticated MTG-B4000D-1AJF and artistic Hokusai-themed models, these watches signal Casio’s continued innovation in blending fashion with function.
A Translucent Take on a Modern Icon
The three new models—identified as the GA-2100K-1AJF, GA-2100K-2AJF, and GA-2100K-5AJF—are now open for pre-order through Casio Japan with a listed price of ¥19,800 (approximately $126) including tax. They share the beloved, streamlined octagonal profile of the GA-2100 series, often nicknamed the "CasiOak" by enthusiasts, but introduce a fresh, see-through aesthetic.
Each model utilizes a matte-finished translucent resin for both the bezel and band, creating a unique, layered look. The colorways are distinctly thematic:
- The GA-2100K-1AJF offers a stealthy smoke gray base with vibrant green accents.
- The GA-2100K-2AJF features a cool bluish translucent casing punctuated by bold orange details.
- The GA-2100K-5AJF opts for a deeper, amber-brown tone contrasted with fiery red highlights.

Design Inspired by Light and Sound
Casio states the design is directly "inspired by nightlife and music festival lighting." This influence is clear in the laser-bright accent colors and the glossy, reflective surfaces of the dials, which are predominantly black to make the neon-colored hands and indices pop. The visual effect is that of a durable tool watch reimagined for a vibrant, after-dark scene.
Robust Construction Meets Everyday Wearability
Beneath the stylish exterior lies G-Shock's renowned toughness. The case utilizes Casio’s Carbon Core Guard structure, which integrates carbon fiber-reinforced resin for a lightweight yet incredibly resilient build. The dimensions remain wearable at 48.5mm × 45.4mm × 11.8mm and a light 51 grams. As expected from a G-Shock, it boasts a 200-meter water resistance rating, mineral glass, and is powered by a reliable quartz movement.
For low-light visibility, Neo-brite luminous material is applied to the hands and markers, ensuring the time is always readable.
Packed with Practical Features
The GA-2100K series is far more than just a pretty face. It’s loaded with functionality suited for global citizens and active users:
- World Time for 48 cities across 31 time zones.
- A precise stopwatch with split timing capability.
- A countdown timer.
- Five daily alarms and an hourly time signal.
- A full auto calendar.
- A double LED light (for the dial and digital display) with an adjustable illumination duration.
The watch promises an accuracy of ±15 seconds per month and a battery life of approximately three years on a standard CR2016 cell.
Availability and Final Thoughts
The new translucent G-Shock GA-2100K models are scheduled to hit the Japanese market in January 2026. This release continues Casio's strategy of refreshing its core silhouettes with contemporary materials and colors, ensuring the G-Shock remains as relevant on the fashion scene as it is in the field.
For those seeking a classic G-Shock experience available right now, a perennial favorite like the Casio GWM5610-1 Solar Atomic Watch remains a top choice for its solar charging and radio-controlled accuracy.
