Seiko 5 Sports SRPJ23K1 Tanjiro Kamado: Official product partnership — not an in-work appearance. Seiko's SRPJ23K1 is a real 500-piece Seiko 5 Sports limited edition, released in 2022 as an official Demon Slayer: Kimetsu no Yaiba collaboration, with a green checkered-haori dial drawn from Tanjiro Kamado's costume, a green camouflage bezel, and a serial-numbered case back. It is a licensed anime-associated watch rather than a model shown on a character's wrist in an episode. (StrapSeeker)
