"UNDONE × Ghost in the Shell: STAND ALONE COMPLEX — The Tachikoma Unit Collection", an officially licensed chronograph released in October 2025 in Blue, Yellow and Grey. It is its own model because no Undone base line uses its movement: the Time Module (Seiko) VK63 meca-quartz in a tricompax layout (24-hour subdial at 3, small seconds at 6, 60-minute chronograph counter at 9), with no date window on the dials; the 41.8mm Urban Sport is a VK64 with a K1 crystal and 30m. Spec table, the same on all three listings: "Japanese TMI VK63 Mechanical-Quartz Hybrid Flyback Chronograph" (the VK63 resets instantly but has no true flyback), 316L steel, sapphire crystal, 41.8mm excluding the crown, 12.7mm including the crystal, rubber strap, 10 ATM / 100m. The text adds an IP coating that recreates the Tachikoma's body colour, hands shaped after its antenna and manipulator arms, the Laughing Man mark and a luminous Section 9 insignia on the dial, and an engraved Tachikoma schematic and S.A.C. emblems on the caseback (a solid back in the photos). The photos show a black tachymeter bezel. No lug-to-lug, lug width, weight or crown details are published. All three were on sale on 2026-10-30, with a set of four "Laughing Man" stickers. Editions. Blue (COL-STS-GHO-BLU-STS, USD 320): blue IP case, blue strap. Yellow (COL-STS-GHO-YEL-STS, USD 320): gold-tone IP case, black strap. Grey (COL-STS-GHO-GRA-STS, USD 320): grey IP case, black strap; recreates the "post-lab" Tachikoma, with an updated tank design on the caseback and no red tail-light detail on the dial. UNDONE × Minion 8-bit Speedster (listed 2023-06, COL-MNS-8BT, USD 399; sold out and tagged archive on 2026-10-30): the second instalment of Undone's Minion collaboration; black-coated case, black tachymeter bezel, white dial with three subdials carrying 8-bit pixel Minions, white rubber strap (photo filed "22mm_rubber_wht"), and a caseback printed with pixel Minions around a spiral and marked "pressure tested to 100 meters" (whether it is a window is not clear from the photo); its spec table matches this model's (VK63, 316L steel, sapphire crystal, 41.8mm excluding the crown, 12.7mm including the crystal, 10 ATM / 100m), and its side photo, filed "SpaceJam_caseside", shows the same case, pushers and crown as the Tachikoma's. The model's release year is left blank because this edition predates the 2025 Tachikoma.
