Seiko Selection Space Brothers Collaboration: Official product partnership — not an in-work appearance. Seiko released this Space Brothers collaboration on November 14, 2025 as two limited references built on the Seiko Selection "Rotocall" digital-watch line, SBJG023 (silver-tone) and SBJG024 (gold-tone), each limited to 824 pieces domestically. The colorways reference a scene in Space Brothers manga volume 40 in which Mutta and Hibito Nanba reunite on the lunar surface: SBJG023's silver case recalls Mutta's spacesuit and SBJG024's gold tone recalls Hibito's Russian-built suit, and both case backs carry the series' cooperation motto and an edition number. It is a real licensed anime-associated watch, not a watch shown on screen. (Seiko)
