Developed from and inheriting the design sensibilities of the first-gen DW-5000C G-SHOCK, the full-metal entry in the digital/analog combo GA-2100 series features a smartphone link.The screwback case, bezel, and band are made of stainless steel; shock-resistant construction not only protects the module from impacts when dropped but also minimizes waste for a simple design.It also inherited the octagonal bezel shape and the dimpled design of the band used in the DW-5000C, created in 1983.High-density mounting technology combines a low profile with a slim and highly functional module.It's also comfortable to wear.The stainless steel bezel is sculpted in 3D by labor-intensive forging, cutting, and polishing, with a circular hairline on the top and a beautiful mirrored polish on the slopes.Fine resin cushioning is implemented between the bezel and the case; the metal exterior provides an impact-resistant structure.The dial is made with exclusive craftsmanship using the microtechnology of Casio's Yamagata factory; vapor deposition is used to apply a fine texture.Low-profile, high-performance digital/analog combination module connects with a dedicated app via Bluetooth communication to retrieve time info and keep time accurately.It also combines practical functions such as Tough Solar technology and high-brightness double LED lights.
