The DW-5000C is the original G-Shock model from 1983. The GMW-B5000 Series has inherited its characteristic square design and been given the full metal treatment along with upgraded features including smartphone linking. The GMW-B5000-1JF has been given a full-metal case by using a shock-resistant fine resin cushioning material inserted between the case and the sturdy stainless steel metal bezel. High-density mounting technology also allows the watch to maintain its size. The back of the watch features a solid Screw Lock Back and has been DLC treated for resistance to wear. Gold ion plating has been applied to the entire case and band for a beautiful color. Visibility too has been enhanced via use of a film solar cell and STN-LCD (liquid crystal). Function-wise, this model comes with Bluetooth® communications and can link with a dedicated app to obtain precise time information. The watch is also packed with practical features including a time correction system that uses standard time and frequency signals (Multi-Band 6), a reliable source of power in the form of Tough Solar technology, high-luminance Full Auto LED backlighting, World Time and day of the week display in six languages. This is a G-Shock model that stays true to its predecessor while undergoing further refinement through the application of a full-metal design.
