Two new Casio G-Shock GA-B2100 collab watches with Tough Solar and Bluetooth launching soon
Shortly after Casio's upcoming GBX-100 and Surfrider collab watches were leaked, we now have our first look at a new set of limited-edition G-Shock watches inspired by the anime series Haikyu!!, commemorating its 10th anniversary. The collaboration features two GA-B2100 models themed around rival teams "Karasuno" and "Nekoma", with each watch reflecting the distinct team colors and character details tied to the series.
The Karasuno-themed model uses a deep navy-and-orange color scheme that goes along with the team’s jerseys and court energy. The watch strap features Hinata's signature jersey number "10" on one end and a white "飛べ" (fly) kanji motif near the lugs.
Meanwhile, the Nekoma edition takes on a red and black theme with the number "5" from Kenma's jersey near the tip of the strap, and the word "繋げ" (connect) scripted on the case band. The cat-themed checker pattern on the strap is an unmistakable call to their nickname, “The Cats.”
Both watches sport Bluetooth connectivity, Tough Solar charging, and world time support - standard fare for the GA-B2100 lineup. From a hardware standpoint, these aren’t introducing new tech whatsoever, but the visual details go all-in. Casio will also roll out dedicated merchandise alongside the watches, which will include Haikyu!!-themed straps, packaging, and character art inserts.
Casio hasn’t confirmed a release date or price just yet, but given past anime collabs like the Dragon Ball and One Piece models, these will likely be limited in number and go fast.
