Groove Ultra-Gambit Zirconium

MOT STUDIO is the rabbit-badged workshop that treats structural tuning as the product, and the Groove is its signature slider family. The Groove Ultra-Gambit opened the brand's chess series in July 2026 as the family flagship, shaped as the Knight piece and first of a planned set.

It runs a mechanical track, never magnetic, with factory high and low tone setups: a stiffer spring against a POM or zirconium bead for the crisp voice, a softer pairing for the muted one. Damping adjusts without tools through a quick-release system, the lanyard hole hides inside the body, and pinned checkerboard plates carry the knight relief on both faces. Each of the two editions is limited to 599 pieces; both build on zirconium, one finished to a bright spectrum with stainless steel, the other blackened with brass lining the knight.

Every piece is inspected and serial checked before dispatch, and ships with TRB authentication. Condition, packaging and completeness are recorded per piece at listing.
