The G-Shock MTG-B2000XD-1A and MTG-B2000YBD-1A are the first MTG-B2000 models to feature carbon fiber parts on the front exterior. Both models have a stainless steel composite band with a resin interior layer.
The MTG-B2000YBD-1A (right) replaces the stainless steel of the bezel frame with multiple layers of carbon and fiberglass sheets, resulting in a frame that is 77% lighter than the stainless steel version. The total weight of the watch is 131 grams, compared to 156 grams for other MTG-B2000 models with a stainless steel band. The layered structure creates red accent lines on the side of the watch, and a distinctive carbon fiber top layer adorns the front of the frame. This top layer is also on the backside of the frame. The MTG-B2000XD-1A (left) has a bezel made of carbon fiber and fiberglass layers, with green accent lines visible on the side. The MTG-B2000XD-1A weighs 150 grams.
The MTG-B2000XD and MTG-B2000YBD feature Tough Solar power, Triple G Resist (shock, centrifugal force, vibration), 200-meter water resistance, Multi-Band 6 auto radio time sync, Bluetooth smartphone link, dual time, 1-second stopwatch (24 hours max), daily alarm, and LED light.
The MTG-B2000XD-1AJF (148,500 yen, tax-included) and MTG-B2000YBD-1AJF (159,500 yen) will be released on October 9, 2021, in Japan. Both models will also be released throughout Asia. G-Shock U.S. is expected to release the MTGB2000YBD1 for $1,200.

Do you think Casio will release carbon fiber/steel combination bracelet to match the B2000YBD?
Do you mean a combination that looks like the GWF-A1000XC-1A? I’m not sure if we’ll ever see carbon fiber combined with stainless steel links. (The composite band on that Frogman is resin and carbon fiber.) If it was going to happen, it seems like it would have happened with the MTG-B2000YBD-1A.

Yes, I was going to mention GWF-A1000XC-1A as the example. More like stainless steel combined with carbon fiber links would look awesome. Not to mention the weight savings. Let’s wait and see.
Yeah hopefully that will happen someday. It’s probably possible, just not developed yet.
Whats the difference between MTG-B2000XD-1AJF and MTG-B2000XD-1A? Do they diff in specs?
They are the same. “JF” means it is meant to be sold in Japan.
