$3,000.00 USD


A GPS hybrid radio-controlled, solar-powered model from G-SHOCK's most luxurious line, MR-G.  

The first watch to be equipped with a shock-resistant structure and GPS hybrid radio solar in a full metal case, it can display accurate time all over the world. Additionally, the clad guard structure makes the crown both operable and impact-resistant, which was previously difficult. The titanium case and band have undergone DLC and deep hardening treatments and are finished in all black to achieve a tight design. Particular attention was also paid to every detail affecting strength and quality, as is reflected in the use of textured polishing, and an anti-reflective coating on the sapphire glass crystal. It is a model that imbues tough men around the world with the pride of MADE IN JAPAN.
