About the Watch in short. G-SHOCK, which has been setting the standard for timekeeping toughness and durability since 1983, announces new GM-6900 Series watches with stainless steel metal bezels. This new model, which fit right in with both high-elegance luxury fashions and modern street fashions, come on the heels of the GM-5600 Series with metal covered bezels.
Enjoy Japanese Unique Features in GM-6900!
Metal-covered Shock-Resistant Construction. Minute protrusions on the outside of the inner case reduce surface contact with the metal bezel. This reflects the design philosophy for the hollow case structure, which protects the module using point contacts and cushions exterior blows.
Glass Fiber Reinforced Resin Case. Glass fibers are incorporated into resin for increased strength. The material’s resistance to shock-induced breakage and bending protects the module from external shock. This case delivers outstanding shock-resistance.
Forged and Molded Bezel. The bezel undergoes about 20 forging processes, then cutting and polishing. It is minutely crafted from a complex, highly uneven molding to a back surface shape that can affect its precision fit into the inner case. The surface is polished to a beautiful mirror and hairline finish.
Metal Front Button. The 6900’s iconic front button, having surpassed its merely functional role in controlling the backlight, gets a metallic makeover. It is grounded in precise design, balancing the button guards and in a shape and angle that is easy to press.
Mirrored Triple Graph Dials. The Triple Graph dials coordinate exquisitely with the LCD and face plate, whose mirror finish complements the metal exterior for complete design harmony.
Negative Type LCD + Electroluminescent Backlight. The negative type LCD brings a stylish cool to the digital display, while the electroluminescent backlight keeps everything visible in the dark.
