Casio is releasing the G-Shock MTG-B1000RB-2A to celebrate the 20th Anniversary of the MT-G (Metal Twisted G-Shock) line of watches featuring cases made of stainless steel and resin. The first MT-G watch was the analog GC-2000 released in November 1999. The following year, the “MTG” prefix was adopted and the line continued in various forms including analog-digital, digital, and analog versions.
The special edition MTG-B1000RB-2A features rainbow ion plating which refracts light in multiple colors to evoke a lunar rainbow. As the name suggests, a lunar rainbow is is produced by moonlight and is extremely faint and difficult to detect with the naked eye unless it is completely dark. This model has a soft urethane band and the special packaging also has a rainbow IP finish.
The MTG-B1000RB is based on the MTG-B1000 which is the first Bluetooth-connected MT-G watch. Notable features include Tough Solar power, a carbon fiber-reinforced case, sapphire crystal, and Triple G Resist. The MTG-B1000 is also known for its innovative new design which is smaller than the previous MTG-G1000.
Casio America announced the MTGB1000RB-2A for a June 2019 release with a list price of $1,000 USD. The MTG-B1000RB-2AJR is a May 2019 release in Japan with a list price of 115,000 JPY. The MTG-B1000RB-2A is also a May 2019 release in Asia.

These are close to $2k as of writting. Will they get new stock before the end of the year so the price can go back down to $1k? Thanks.
It’s a limited edition, so there won’t be any new ones made and the price will probably not go down.
