Authentic, genuine domestic product. Box, manual, and extra links for the bracelet are included. Condition: Fully functional. Used approximately once a week for about six months, with a protective glass film on the glass. There are minor scratches on the metal parts due to use. The GMW-B5000 series is a full-metal version of the first G-SHOCK, the DW-5000C, which was born in 1983, and features smartphone link and other functions. It has a shock-resistant structure that sandwiches a fine resin buffer between the metal bezel and the main body case made of stainless steel. The size is also maintained thanks to high-density mounting technology. It features a heavy-duty screw-back case and is DLC-treated for excellent abrasion resistance. The metal band pieces are dimpled, inheriting the design of the first model's resin band. The visibility is also improved by using a film solar cell and STN-LCD (liquid crystal). The face features a vivid green glass vapor deposition. In terms of functionality, it can connect to a dedicated app via Bluetooth® communication to obtain accurate time information. It also has practical features such as a time correction system using standard radio waves (Multi Band 6), stable operation with Tough Solar, a high-brightness full-auto LED backlight, world time, and day-of-the-week display in six languages. This is a G-SHOCK that has been further refined with a full-metal design while inheriting the origins. Casio CASIO G-SHOCK
