First G-SHOCK, the brand that has constantly been testing the limits of timepiece toughness since 1983, released the GMW-B5000, an all-metal version that recreated the look of the very first G-SHOCK. Now comes the AWM-500 Series of new full-metal analog-digital models. Based on the AW-500, G-SHOCK's first analog-digital combination timepiece that was released in 1989, these new full-metal models employ hard stainless steel material for their bezels and bands. Other features include screw-in backs and three-dimensional hour markers.
