The MR-G is the most high-end of all Casio collections. The present MRG-G1000B-1ADR features an elaborate, DLC-coated titanium case finished to a high degree and topped-off by a glareproof sapphire crystal. Time is automatically adjusted -when needed- using both GPS and radio signals, while its battery is charged by solar cells on the dial. The MR-G G1000 is also fitted with Casio's 'Tough Movement' technology, which regularly checks and corrects the relative hand position.
