Casio G-Shock Octagonal Slim MRG TITANIUM watch with COBARION Bezel MRGB2100D-1A

The MRGB2100 features case and bezel components made with the hard titanium alloy, Ti64. The bezel top is fashioned from COBARION, an alloy that is four times harder than pure titanium and has a brilliant gleam comparable to platinum. The band is made of another special titanium alloy, DAT55G, which is both extremely hard and highly workable. We make the most of the extra-hard metal materials to create ultra-smooth mirror finishes and apply titanium carbide (TiC) coating for even greater scratch-resistance.
