Seiko Nano Universe Limited Edition SCXP111 & SCXP121 Unboxing

This is the new limited edition that Seiko works with Nano Universe in 2018. Both SCXP111 and SCXP121 are limited to 300 each, and are only sold in Japan (at least at the moment). The sizes of these two are 37.5 mm and 33 mm respectively. Cheap, but aesthetically elegant watches in my opinion. The other watch used for comparison is a Seiko SBDC053.

Are these genuine? The ones released in 2017 had a black case not silver? Did Seiko launch event more of these with new cases?
