Casio G-Shock Metal GMW-BZ5000BD-1AER

The G-SHOCK GMW-BZ5000 takes the 5000 line to a new level of style and technology, directly inheriting the DNA of the original G-SHOCK and transforming it into a completely revamped full-metal design. The fruit of over forty years of shock resistance research and a co-creation process between designers and artificial intelligence, this model introduces an innovative structure that extends the case all the way to the lugs to further reduce shock transmission. The modern and complex shape, particularly evident in the side view, highlights the watch's structural beauty, while the internal resin protector temporarily deforms to absorb shock while maintaining the brand's signature standards of resistance. The stainless steel case with a screw-down case back ensures solidity and water resistance.

The high-definition MIP LCD display has been optimized for solar charging and offers eight display styles, including the more traditionally aesthetic STANDARD and CLASSIC modes. Thanks to its high contrast and wide viewing angle, readability remains excellent even in direct sunlight, maintaining a superior level of detail.

The layout recalls that of the original G-SHOCK, but combines it with advanced features such as Bluetooth connectivity via the CASIO WATCHES app, Multiband 6 technology for automatic time adjustment, Tough Solar, and a high-brightness LED for visibility in any situation. Manufactured at Casio's Yamagata plant, where the brand's history began, this model represents a new chapter in the G-SHOCK tradition, combining innovation, precision, and Japanese quality.
