This is the GMW-B5000 Series, which includes the distinctive square design of the original DW-5000C G-Shock model from 1983 while adding a full metal finish. This model has a unique design that employs laser etching across the entire watch. The watch has been given a full metal case by using a shock-resistant fine resin cushioning material between the case and the sturdy stainless steel metal bezel. After black IP treatment has been applied across the entire case and band, a special laser etched finish is used to create a Grid Tunnel. The concept of the 5000 Series, which has evolved over the decades since 1983 without changing its look, aligns with the Grid Tunnel image of "the flow of time from past to present" to create the watch's overall design.
