Seiko Oshi no Ko Kana Arima Model
More actions
The Seiko Oshi no Ko Kana Arima Model is one of five character watches from Seiko's Oshi no Ko collaboration, alongside Ai, Aqua, Ruby, and Akane Kurokawa models. It reached JumpIchiban's storefront in September 2025, after Ai's December 2024 debut, at PREMICO's shared ¥59,800 (¥65,780 tax-in) price, limited to 2,000 pieces. The chronograph dial fades from deep crimson to pale pink, with a gold "first star" (一番星) at 12 o'clock for child actor Kana Arima and a subdial at 6 o'clock lettered "Kana Arima" over a curling decorative crest. Red chronograph hands break from the other models' gold or blue hands, and the caseback carries her signature and the ©Aka Akasaka x Mengo Yokoyari/Shueisha, "OSHI NO KO" Partners credit. It ships on a brown leather strap and is licensed merchandise, not a watch shown on screen. (Seiko; JumpIchiban)
