How Private Treaty Watch Acquisitions Work: 4K Pre-Shipment Assay Dossiers, Zero Buyer's Premium & Insured Escrow

A Private Treaty horological acquisition is a confidential, direct-from-vault transaction that eliminates the 25%–27% public auction house buyer's premium and protects the collector through a mandatory 4-stage verification protocol: wrist sizing, personalized 4K Mettler-Toledo + Fischer XRF + Witschi video sign-off, escrow settlement, and insured armored delivery.
