House · Collector Index
The collector index.
Everything the house has written for collectors, in one place: how to sell each maker, what selling actually costs, how valuation and authentication work, the scale of the counterfeit trade, and the guarantee that sits behind every transaction. Start with the question you have.

Buying & sourcing
A short glossary
Buyer's premium — the fee an auction buyer pays on top of the hammer price (27–28% at the lower tier in 2026). It comes out of what a buyer will bid, so a seller carries it indirectly.
Escrow — funds held by a regulated third party and released only on the buyer's inspection, so neither side transacts on trust.
Extract from the Archives — a Patek Philippe document confirming a specific watch's date and original specification.
Full set — a watch with its original box, papers and accessories; it sells for more than the sum of its parts.
Superfake — a counterfeit good enough to pass a surface glance, defeating the old visual tells.
