Antiquorum Watch Auction Results Scraper

Scrape realized prices, lot estimates, and detailed watch information from Antiquorum's complete historical auction catalog — the world's dedicated watch auction house with archives going back to 1989.

What This Actor Does

Antiquorum (catalog.antiquorum.swiss) is the premier dedicated watch auction house, covering Patek Philippe, Rolex, Audemars Piguet, and independent watchmakers. Their realized-price archive is the gold-standard comp set that appraisers, dealers, and insurers use for vintage/collectible watch valuation.

This actor crawls the hierarchical auction catalog:

1. Discovers all auctions by year (1989–present)
2. Extracts all lot URLs from each auction's catalog page
3. Scrapes full lot details: title, brand, model, reference number, estimates, realized price, condition grading, images, and more

Use Cases

• Watch valuation — historical realized price comps for appraisals and insurance
• Market analysis — price trend tracking across decades of auction data
• Dealer research — reference-normalized pricing for vintage Patek, Rolex, AP, etc.
• Auction analytics — sell-through rates, premium vs. estimate performance

Input

Field	Type	Description
maxItems	integer	Maximum records to return (required)
startYear	integer	Earliest auction year to include (default: 2024)
endYear	integer	Latest auction year to include (default: current year)

Example input — scrape 2025–2026 auctions, up to 100 lots:

{
  "maxItems": 100,
  "startYear": 2025,
  "endYear": 2026
