Inheriting the DNA of the first G-SHOCK model (DW-5000) the GW5000U-1 is constructed with a solid metal case and a screw back. This timepiece is also equipped with advanced technology, Multi-Band 6 that receives standard radio waves from up to 6 stations around the world. The metal inner case and screw back are stainless steel. DLC (diamond-like carbon) coating is applied to the screw-back to enhance wear resistance and is also mirror-processed to create a luxurious finish. In addition, the resin band uses soft urethane that is comfortable to wear.
