Casio G-Shock Full Metal Bluetooth Digital Gold Watch GMWB5000GD-9 GMW-B5000GD-9DR

It has been 35 years since the introduction of the DW-5000C onto the world watch market. Now for 2018 G-SHOCK introduces additions to the new exterior, new structure, and new module GMW-B5000 lineup, equipped with a Connected Engine.
The full-metal hard stainless steel cases and the bezels of these two models have ion-plated finishes in either black or gold. The cases and band also feature hairline finishes to maximize the elegance and presence of the metal. Light-on-dark LCDs further add to the overall chic look of these timepieces.
The base model is the GMW-B5000, which is the model from which we reviewed our hollow case structure and developed an even higher level of shock resistance. Fine resin shock absorbers between the metal bezel and case created a shock resistant structure for a full-metal case. Innovative new band connections use highly shock resistant TROGAMID® to lessens the effects of impact to the band pipes. The back covers of the thick screw back cases of these models come with a diamond-like carbon (DLC) finish that is highly wear resistant. A film solar cell that maintains display clarity and an STN-LCD are used to ensure easy reading of display information, even from an angle.
Use of the latest-version engine makes it possible to achieve high-density component mounting without affecting the size of the finished timepiece. Advanced technology modules are packed into stunning designs that are finished using some of the best that technology has to offer.
Function-wise, these models are designed for outstanding timekeeping accuracy using Bluetooth® data communication and MULTIBAND 6, which supports automatic time setting adjustment based on one of six time calibration signals around the globe. Time information also can be acquired from an internet time server using the G-SHOCK Connected*1 app running on a smartphone. Other functions include Tough Solar in combination with CASIO original power saving technology that delivers a stable supply of power, high-brightness Full Auto LED illumination, World Time, and more. A selection of six languages for the day of the week indicator*2 provides localization at the press of a button. All of this means that accurate timekeeping is ensured no matter where in the world your travels take you.
