In a move that merges rugged durability with sophisticated, urban aesthetics, Casio has just unveiled a striking new collection of Full Metal G-Shock watches. The announcement, made in Japan, introduces three monochromatic variants that are poised to redefine what it means to wear a tool watch in a modern context.
Gone are the brightly colored accents and resin-heavy builds of G-Shock's past. This new lineup, comprising the models GMW-B5000BT-1JF, GM-B2100BT-1AJF, and GMC-B2100BT-1AJF, doubles down on a stealthy, unified look. The defining feature? A compelling black octagonal top bezel that frames a clean, white-on-black digital dial, creating a visually striking and legible interface.
This launch signifies a continued evolution for the G-Shock brand, cementing its place not just in the toolbox, but on the wrists of design-conscious individuals seeking a timepiece that is both technically proficient and stylistically versatile.
A Design Statement in Steel and Shadow
The most immediate takeaway from this new collection is its uncompromising monochromatic design. Crafted from stainless steel, each watch presents a cohesive, tonal look from case to bracelet. The black ion-plated octagonal bezel isn't just an accent; it's the centerpiece of the design, paying direct homage to the iconic shape that has made G-Shock a global phenomenon for decades.
The minimalist approach extends to the dial, where a "negative display" (white text on a black background) ensures critical information is clear at a glance. This cohesive color story makes these timepieces exceptionally easy to pair with anything from casual weekend wear to a more polished, professional outfit.

Smart Connectivity Meets Atomic Precision
Beneath the rugged exterior lies a technologically advanced core. Each model in this series is equipped with Bluetooth® connectivity, allowing it to seamlessly pair with both Android and Apple smartphones. This enables automatic time synchronization, ensuring you're always perfectly on schedule. The watches can also manage alarms for up to five separate events and keep track of time across 300 world cities—a boon for frequent travelers.
The GMW-B5000BT-1JF model takes accuracy a step further by incorporating a 6-band radio receiver. This feature allows the watch to automatically sync with atomic timekeeping signals in Japan, North America, Europe, and China, all without needing a smartphone connection. For those who admire this model's tech but prefer the classic G-Shock feel, a similar variant with a resin wristband, the GMW-B5000-1JF, is also available for purchase. You can find this model on Amazon here .
A cleverly integrated feature enhances daily utility: with a simple button press, wearers can record their current location, date, and time directly to their paired smartphone. This creates a convenient log for tracking daily activities, travel routes, or memorable locations.
Built to Last: The Core G-Shock Philosophy
Despite the premium metal construction, these watches retain the legendary toughness the G-Shock name is built upon. Inside the stainless steel bodies, resin impact guards are strategically placed to absorb and dissipate shocks, ensuring the module remains protected from life's unexpected bumps.
They are also built to withstand the elements, boasting a formidable 20 ATM water resistance, making them suitable for professional marine activity and surface water sports.
Powering these feature-packed watches is Casio's renowned Tough Solar technology. A high-efficiency solar panel is fitted discreetly beneath the watch face, converting both indoor and outdoor light into energy. This charges the internal rechargeable battery, effectively granting the watch an unlimited runtime under normal usage conditions.
Rounding out the professional toolset are essential functions like a 1/100th second stopwatch and a countdown timer, upholding G-Shock's legacy as a reliable instrument for timing-critical tasks.
Pricing, Availability, and First Looks
The new Full Metal G-Shock collection with the black octagonal bezel is positioned as a premium offering.
