Executive Technical Summary • Verified Horological Standard

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.

Key Quantitative Laboratory Takeaways

  • Public horological auctions charge a 25% to 27% buyer's premium plus local VAT, whereas 18K VIP Geneva Private Treaty allocations carry a 0% buyer's premium.
  • No timepiece is ever sealed for transit until the client reviews and approves their personalized 4K Vault Dossier video bearing their unique allocation code and date.
  • Settlement is supported via Private Client Escrow, international bank wire (SWIFT/SEPA), and instant institutional digital assets (USDT, USDC, BTC, ETH).
  • Every shipment is 100% insured door-to-door via priority DHL Express Value-Courier or Malca-Amit / Ferrari Group armored logistics, backed by our 14-day inspection window.

Why Discerning Collectors Prefer Private Treaty Over Public Auctions

For collectors acquiring solid 18K gold and 950 platinum horology—where individual pieces contain over 130 to 200 grams of precious metal and intricate mechanical complications—public auctions present two major drawbacks: punitive 26% buyer's premiums and zero mechanical or metallurgical recourse once the gavel falls. Through our Geneva Private Treaty desk, every allocation is conducted at a fixed, transparent private treaty price with zero buyer's commission and full laboratory accountability before a single shipment leaves the vault.

What happens if I want a different dial or link adjustment after seeing my 4K QC video?

Because your 4K Vault Dossier is recorded before dispatch, our watchmakers can adjust the bracelet length, regulate the beat rate, or switch your allocation to another lot immediately at zero cost.

Are all spare solid 18K gold links included if I select a smaller wrist size?

Yes. We size the bracelet so the watch fits your wrist out of the box, and every removed solid 18K gold or platinum link is sealed in a velvet pouch inside your presentation box.

Is my shipment insured against loss or transit damage?

Yes. 100% of the full replacement value of your timepiece is underwritten by our logistics insurance until you sign for the parcel at your designated delivery address.
