Methodology
Studied properly — what the phrase obligates. Eight rules, non-negotiable, printed where everyone can check them.
- Asking is asking; realized is realized; estimates are estimates.
The three price kinds are never mixed and never relabeled. An asking price is what a seller hopes for; a realized price is what a buyer actually paid; an estimate is a hope with a gavel.
- The honesty gate on realized sales.
A figure enters the realized column only with evidence: a published hammer price (buyer’s premium status noted) or a marketplace sale verified live showing sold price and date. Every record carries a verified date and a verified note naming the evidence.
- Gone is gone — never sold.
Listings that disappear and auctions that end without a published result are logged as off-board — noted with their last-seen price, never presented as sold.
- Upcoming lots are context, not sales.
Auction-house upcoming lots feed the market-note context only. They never appear in a sales table.
- Prices stay in their listed currency.
No silent conversion. A franc figure stays a franc figure.
- A quiet week is a quiet week.
Empty shelves render the honest line: “No verifiable sales recorded yet.” Nothing is padded, estimated, or invented.
- Every number carries its check date.
No undated figures. If we can’t say when it was checked, it doesn’t print.
- Education, never advice.
Market data is published for information and education only — never as investment advice. Vintage watch prices move on condition, provenance, and the room on the day.
Ten references, eight venues, four salerooms.
Nightly scans across Chrono24, eBay, Analog:Shift, HQ Milton, Watch Club London, Bulang and Sons, Grailzee, and Catawiki, plus upcoming-lot tracking at Christie’s, Phillips, Sotheby’s, and Antiquorum. The market reports file every Wednesday morning; the first dossier lands October 14, 2026.
