G-Shock Japan is releasing the GM-B2100SD-1AJF (84,700 yen) in October, which is also expected to be released worldwide. At first glance, it may be mistaken for the GM-B2100D-1A which was one of the three GM-B2100 series launch models in 2022. The new GM-B2100SD-1A has a higher-contrast dial, with hour markers that are a lighter shade and closer to silver. The hands are also a much lighter shade. The GM-B2100SD-1A otherwise looks like the GM-B2100D-1A, with a black dial and inverted LCD display. The Full Metal GM-B2100SD-1A is made in Japan and features a stainless steel case, screw lock case back, Tough Solar power, and Bluetooth mobile link.
The difference of the GM-2100SD-1A (left) from the GM-2100D-1A (right) is very apparent when viewed side-by-side.
