Features:
Blue accents to complement the metal exteriors
Vibrant blue accents adorn the dial of the GM-B2100AD and the perimeter of the face of the GMW-B5000D, enhancing their sleek metal exteriors. The distinctive metallic tone, achieved through vapor deposition, beautifully complements the silver gleam of the full-metal cases, adding a stylish flair to your wrist. Whether your style is formal, sporty, or casual, these watches effortlessly coordinate with any wardrobe.

Dial Finishes for Intricate Refinement
The dual-layer dial construction showcases both the inset dial and LCD portion with unique finishes. A minute grind-mark finish and vapor deposition applied to the inset dial ring highlight the precision of Yamagata Casio's die moulding technologies, resulting in meticulously detailed surfaces. Additionally, vapor deposition on the dimensional index marks and the indicator hand enhances the metallic texture, creating a dial design that harmonizes beautifully with the watch’s metal exterior.

Full-Metal Shock-Resistant Structure: Honoring Origins, Embracing Innovation
This timepiece maintains the iconic shock-resistant structure of the original G-SHOCK, now encased in a durable metal exterior. Fine resin buffering components are strategically installed between the stainless-steel bezel and case, enhancing shock absorption. A three-pronged structure at the band’s connective part disperses shocks to the connecting pipes, ensuring durability. Additionally, the metal band pieces are dimpled to mirror the resin band design of the first G-SHOCK. The case back features a screw-lock construction, ensuring a secure and tight seal.

Forged Bezel and Case: Crafted with Passion for Refined Details
The bezel and case undergo meticulous processes of forging, cutting, and polishing, precisely shaping them into robust and powerful forms. Every detail, including the intricately shaped back, is crafted to ensure a precise fit. A hairline finish is applied to the bezel top, while the beveled edges are given a mirror finish, maximizing the metal's textural appeal.
