-Casio G-Shock Full Metal Tough Solar Multi-Band 6 Bluetooth Silver-Black Face

GMW-B5000BT-1JF

A Full‑Metal Tribute in Black & Brilliance

Casio G‑Shock presents the GMW‑B5000BT‑1, a bold reinterpretation of the original square‑case DW‑5000C. This full‑metal masterpiece is finished in deep black ion plating, accented with a shimmering glass vapor deposition that brings a refined brilliance to its rugged form.

The design pays homage to G‑Shock’s roots while elevating the aesthetic into a modern collector’s piece. The iconic square face, brick‑pattern dial, and retro LCD layout remain true to the 1983 original, yet the sleek black finish and metallic accents give it a contemporary edge.

Every detail reflects G‑Shock’s philosophy of toughness and style — from the solid stainless steel construction to the subtle interplay of matte and polished surfaces. It’s a watch that speaks both to heritage and to modern sophistication.

The GMW‑B5000BT‑1 is more than a watch — it’s a design statement, blending G‑Shock’s uncompromising toughness with a sleek, modern aesthetic. Whether you’re a seasoned collector or discovering the legacy for the first time, this model embodies the spirit of G‑Shock in a form that’s both heritage‑rich and future‑ready.
