Casio G-Steel GMW [GMW-BZ5000BD-1DR]

Enhance your style with some seriously sophisticated timekeeping from the 5000 line. Directly descended from the first-ever G-SHOCK , the GMW-BZ5000 carries on the evolution of function and material in a transformative, unprecedented design.

Welcome to a new chapter in full-metal G-SHOCK watches. Tapping into shock-resistance data gathered over 40 years of G-SHOCK testing, we delved into co-creation between human designers and AI to find all-new methods of generative structural and exterior design.

We kept the iconic form of the original G-SHOCK, while developing a new structure that extends the case all the way to the lugs to even further mitigate shock transmission. The intricate, modern shape, seen from the side, highlights the design’s structural beauty. An internal protector made of resilient resin temporarily deforms to absorb shocks, achieving a timepiece with a full-metal exterior that meets G-SHOCK shock-resistance standards. The stainless-steel case employs a screw-lock case back to ensure a tight seal.

Additionally, to make solar-powered operation possible for the high-definition, full-dot MIP LCD with memory embedded in each pixel — a display commonly used in G-SHOCK sports models — we developed a more energy-efficient version. This new display offers a total of eight different display styles: you can choose from two distinct styles — the easy-read STANDARD and CLASSIC for a traditional 7-segment look — across four display modes. The display employs a high-precision, high-contrast MIP LCD with a wide viewing angle that not only charges from ambient light — sunlight or even fluorescent lamp light — but enables more detailed rendering for outstanding readability even in bright outdoor spaces and direct sunlight. 

The time mode display layout carries on the look of the first-ever G-SHOCK, with traditional styling taking on advanced functionality. Download the CASIO WATCHES app to pair with your smartphone via Bluetooth®. With Multiband 6, Tough Solar charging system, and high-brightness LED light, you have complete practical utility at your fingertips. 

This new chapter in G-SHOCK is crafted at Yamagata Casio, the “mother factory” where the original G-SHOCK story was written
