New Compact G-Shock Models from Casio
Casio has just introduced some really small G-Shock watches within their GMD-B300 series, with pre-orders now starting in Japan, and they’re planning to officially launch around May 2026. These watches are notable mainly because of their smaller size, basic fitness features, and overall practical usage.
Design and Dimensions
Both models — the GMD-B300-2JF in navy and GMD-B300-7JF in an off-white color — share very similar looks and features. They measure 46.4 × 43.8 × 12 mm and weigh just 41 grams. The smaller size makes them much more comfortable for long wear, especially for those who think the usual G-Shocks are just too bulky.
Fitness and Connectivity Features
The GMD-B300 series include a built-in pedometer that automatically counts your steps all day long, showing both your daily steps totals and how close you are to your goal. The watch also offers step graphs by different times of day. Plus, it connects via Bluetooth, allowing you to sync with the Casio Watches app. Through this app, users can manage their workout logs, tweak settings, and review step data and basic time adjustments, making it a light but useful integration.
Functionality and Durability
Standard digital G-Shock functions are included. This covers dual time display, stopwatch, countdown timer, five alarms, and a fully automatic calendar. The LED backlight features auto-light activation and lets you adjust how long it stays on. To save power, it has a power-saving mode, and Casio estimates the battery will last around two years – a bit less than some simpler digital watches but understandable because of the added fitness and Bluetooth features.
Build and Pricing
The case and band are made from resin, but Casio is using eco-friendly biomass-based plastic for the cases and straps. The watches are water-resistant up to 200 meters. Even with their smaller size, they keep shock resistance and the robust build Casio is known for.
Pricing and Availability
The retail price is set at ¥17,600, which roughly translates to about $110 to $120 depending on the current exchange rates. Pre-orders are currently only available in Japan, but the watches will likely be accessible in more regions soon.
