RGATT is a provenance registry, not a place to buy or sell watches

RGATT operates a provenance and traceability registry for fine watches. It does not list watches for sale, is never a party to a sale agreed between members, and never holds, escrows or moves funds relating to such a sale. Registration establishes the authenticity of a piece as a best-efforts obligation and is not a warranty of its condition. A clean result in the stolen registry means no theft report matches, not that a watch is guaranteed free of any claim.
