Casio MR-G MRG-B2000B-1A1

MR-G is the top tier of G-Shock, assembled on the Premium Production Line at Casio's Yamagata factory, and the MRG-B2000 is its large analogue model, sharing the 49.8 mm width, 16.9 mm height and 54.7 mm length of the GPS-equipped MRG-G1000 and MRG-G2000. It drops their GPS and sets itself instead by Multi-Band 6 radio or from a phone over Bluetooth, running on Tough Solar with dual time, a stopwatch, a countdown timer and an alarm. The titanium is deep-layer hardened and DLC-coated, and on the basic black MRG-B2000B-1A1 the coating covers the whole watch. G-Central points out that although its Japanese reference ends in JR, usually the mark of a limited edition, this one serves as a standard model in the range. The crystal is anti-glare sapphire, water resistance is 200 m and the watch weighs 150 g.
