Chrono24 is a German online marketplace for luxury watches, founded in 2003 and headquartered in Karlsruhe, Germany. It is the largest dedicated platform for buying and selling high-end timepieces, listing hundreds of thousands of watches from professional dealers and private sellers in more than 100 countries.
The marketplace covers new, unworn, and pre-owned watches from brands including Rolex, Patek Philippe, Audemars Piguet, Omega, Cartier, and independent watchmakers. Chrono24 does not own the inventory; instead it provides the transaction infrastructure: an escrow service that holds buyer payments until the watch is received and approved, buyer protection with authenticity checks on eligible transactions, and secure international payment processing. Its Watch Collection tool and market data give collectors price histories and value estimates drawn from the platform's transaction volume, making Chrono24 a widely cited reference for secondary-market watch prices.
The company operates local platforms in multiple languages, runs offices in cities including Karlsruhe, Berlin, Hong Kong, and New York, and has raised investment from backers including General Atlantic, Insight Partners, and Bernard Arnault's family office Aglae Ventures. For collectors, Chrono24 functions both as a global storefront for dealers and as a peer-to-peer venue for private sales.
