The AWM500-1 is a full-metal version of the AW500-1E, which was released in 1989 and introduced the first analog-digital models to the G-SHOCK lineup. The face of the watch has Arabian numeral hour markers at 15, 30, and 45 minutes for easy reading. The bezel, case and band have a black ion-plated (IP) finish to reproduce the color of the original A500 watches. A bracelet-type metal band with rounded elements reproduces the shape of the AW500 band, and the back cover is a screw type. Other features include radio-controlled atomic timekeeping, Tough Solar, high-brightness Full Auto double LED illumination, World Time, and more.
