The case and bezel are stainless steel, following the octagonal bezel shape of the DW-5000C, with a fine resin buffer set between the bezel and case to deliver shock resistance in a metal exterior. The bezel is shaped three-dimensionally through forging, cutting, and polishing — hairline finished on top and mirror polished on the angled surfaces — while the indices and inner-dial ring get fine machining and vapor deposition for a premium look. The band is Tough Silicone, balancing wear resistance with comfortable fit, with gunmetallic vapor deposition and a hairline finish on the underside to match the full-metal case.\u003c\/p\u003e\n\n\u003cp\u003eHigh-density mounting technology enables a slimmer build, and Bluetooth connects to the dedicated app to keep accurate time information.
