Casio G-Shock GA-B2100LUU-8A

This professional product description is designed for the GA-B2100 "Urban Utility" series, a high-tech evolution of the iconic octagonal silhouette that merges gorpcore aesthetics with advanced solar and Bluetooth® functionality.

Product Overview

The GA-B2100 Urban Utility series delivers sporty practicality with a refined street sensibility. Taking inspiration from the "gorpcore" fashion movement—which blends functional outdoor gear with urban style—this model comes in subtle blue-gray and olive-green tones that integrate seamlessly into a modern wardrobe.

While the aesthetic is understated, the technology is anything but. This model maintains the distinctive octagonal form of the original 2100 series but upgrades the experience with Tough Solar power and Smartphone Link connectivity. Built with a Carbon Core Guard structure and eco-friendly bio-based resin, this timepiece provides a lightweight, comfortable fit while upholding the legendary standards of G-SHOCK toughness.

Gorpcore Fashion Meets High-Tech Utility

A New Standard of Style

The GA-B2100 Urban Utility series reflects a shift toward more versatile, nature-minded design. The use of bio-based resin not only reduces the watch's ecological footprint but also provides a high-quality, matte texture that feels soft against the skin. These subtle hues make it an ideal companion for technical outerwear and minimalist street fashion alike.

Reliable and Efficient

With its rechargeable battery, this watch can operate for up to 7 months on a full charge with normal use—and up to 18 months in total darkness with the power save function enabled. The addition of the "Hand Shift" feature and the high-contrast digital windows ensure that your data—from world time to the countdown timer—is always accessible at a glance.
