Appreciate luxurious quality with a slim G-SHOCK MR-G crafted with cutting-edge metals and meticulous finishes.
A study in metalwork, the MRG-B2100 features a case and bezel crafted from super-strong titanium alloy Ti64. The top of the bezel is made of COBARION¹, an alloy four times stronger than pure titanium and as brilliant as platinum. The strap is made of another special titanium alloy called DAT55G², which is extremely hard and workable. We make the most of extra-hard metallic materials to create ultra-smooth mirror finishes and apply a titanium carbide (TiC) coating for increased scratch resistance.
The bezel alone is made up of 27 different components, in an intricate construction unique to G-SHOCK’s shock-resistant performance. Each individual specimen is individually and meticulously polished to achieve an extraordinarily detailed textual appearance. The cutting-edge Multi-Guard structure incorporates pads between different parts of the multi-component bezel and case, to ensure exceptional shock absorption for the bezel and to protect the dedicated MR-G module with gold-plated locking plate.
The watch face is inspired by the traditional Japanese art of interlocking woodworking called kigumi which, like the bezel of the MRG-B2100, involves the use of myriad small components. This traditional craftsmanship is reflected in the complex two-part structure of the indicators and the depth and dimension of the dial’s lattice pattern. The small openings on the dial, a craftsmanship that requires maximum precision in manufacturing technology, let through a sufficient amount of light to generate the necessary solar energy and always keep you up to date.
This masterpiece is not just a stunning celebration of metals. It also offers exceptional functionality, thanks to radio-controlled calibration and pairing with your smartphone via Bluetooth®.
