*Based on a Casio survey as of February 2021.
The watch features a stainless steel bezel in a sophisticated shape. With painstaking attention to detail, even different facets of the same part are uniquely finished by applying lengthwise, crosswise, or circular hairline and mirror finishes, polishing processes and more. The result is an impressive array of metallic surface textures that captivate the eye from every angle.
A power-saving module enables the use of an opaquer dial, and highly chromogenic dial colouration is achieved with multilayer vapour deposition. Vapour deposition is applied to the iconic G-STEEL dial indicator and bridge parts as well as parts of the face design, proving the meticulous care taken through the very last detail.
Carbon fibre-reinforced resin is used as the material for the case to ensure shock resistance while reducing weight and delivering the slimmest case in the G-STEEL line, at only 12.9 mm. The newly developed form of the button guards makes it possible to offer generously sized stainless steel buttons even in this extra-slim design.
Offering strength, lightness and excellent weather resistance, a carbon fibre-reinforced resin case protects the module. Additionally, buffering components made of resin mounted between the upper and lower bezels help absorb external shocks.
Optimised, high-density mounting of the circuit board structure made it possible to slim the module. A substantial reduction in power consumption was also achieved by reducing the number of watch hands to two and adopting a low-power Bluetooth® system. The ability to solar charge with an opaquer dial allowed for a high degree of freedom in dial design.
