It's claimed that the "case" will be steel and yellow gold, see below.

Case is steel and yellow gold (3N), dial is black, blue, with yellow colour traces (this can refer to printing) with applied markers and lume. Hands are yellow gold (3N). Bezel insert is ceramic and black, but with gold lettering I believe. Sapphire crystals front and back. Back crystal will have an Apollo 11 medallion. Movement is 3861.
