Welcome the MRG-B5000, based on the first-ever G-SHOCK and crafted with the state-of-the-art metals and meticulous finishes that are the hallmark of the MR-G flagship line. These breakthrough timepieces are a study in metal craftsmanship. The case and bezel are made of Ti64-based super-hard titanium alloy, while the band is made of another special titanium alloy, DAT55G, that is both three times harder than pure titanium and highly workable. The bezel top is crafted in COBARION, a cobalt-chrome alloy four times harder than pure titanium. The bezel alone consists of 25 different components, each individually polished for a stunning detailed texture. The state-of-the-art Multi-guard Structure incorporates flat springs and silicone buffers into the multi-component bezel, ensuring outstanding shock absorption to protect the dedicated MR-G module with gold-plated retainer plate. Inspired by ink wash painting and calligraphy done in blue ink, the MRG-5000BA features band screws and bezel components ion-plated in blue against a base of black diamond-like carbon coating. Touches of blue vapour deposition add bold interest to the watch face, and the iconic brick pattern is a nod to the original DW-5000 G-SHOCK design. These metallic beauties deliver when it comes to function, too, with radio-controlled calibration and smartphone pairing via Bluetooth .
