Add to compare

The MRG-B2100 expands the popular octagonal 2100 line into the realm of the peak G-Shock MR-G series, which is made in Japan at Casio’s Premium Production Line. The MRG-B2100 has a full analog display and is made of Ti64 and DAT55G titanium alloys, along with a Cobarion top bezel. The solar-powered MRG-B2100 is the only 2100 series so far to be equipped with Multi-Band 6 automatic radio time adjustment, and it also has Bluetooth smartphone link that can also provide auto or one-touch time adjustment. The original 2100 series (GA-2100) was released in 2019 and was designated by G-Shock as one of its four “masterpiece” lines within just a few years, joining the ranks of such iconic series as the DW-5000/5600, DW-6900, and GA-110.
