Casio announced G-SHOCK in Black Full-Metal Design

Casio announced G-SHOCK in Black Full-Metal Design, the latest addition to its G-SHOCK brand of shock-resistant watches. This is based on the GMW-B5000 watch model, the original full-metal take on the first-ever G-SHOCK watch. This new GMW-B5000MB features an array of detailed finished that come together in a refined black design.

The GMW-B5000MB brings together individual components treated with honing finishes* and multiple polishings in a premium-quality, shock-resistant watch with a uniquely appealing look that makes the most of rich texture and feel.

The entire exterior of the timepiece is honed and treated with black ion plating to deliver matte black sophistication, and additional finishes are applied to individual details. The hairline finish is applied to the side of the bezel and the sides of the band. It retains a metallic texture while tempering the shine. The mirror finish, by contrast, adds a glossy shine to the surface of the screws, buttons, and other details.

Top surface of bezel treated with ?new finishing process

For this latest G-SHOCK GMW-B5000MB-1DR watch, Casio adds a new finishing process as well. After the initial black ion plating, the top surface of the bezel is polished again with a hairline finish to expose most of the stainless steel beneath, with its silver-coloured gleam. The chic and seamless integration of the silvery hue of the stainless steel of the bezel and matte black of the body, complemented by multiple intricate finishes, results in a beautifully detailed, quality design with a one-of-a-kind, sophisticated look.

Functions wise, the GMW-B5000MB-1DR comes with standard radio wave reception and smartphone Link connectivity, which allows the owner to use the G-SHOCK Connected app to maintain precision timekeeping and easily manage alarms, world time, and other settings. The watch also has a handy reminder and phone finder function when it is connected with the app.

The G-SHOCK GMW-B5000MB-1DR will be available at and in G-SHOCK stores in April.
