About Crownly

Crownly is the deep horology data layer for collectors. We aggregate listings from every major marketplace — eBay, Catawiki, Chrono24, community forums — and enrich them with reference-level data: calibre, variants, production years, materials, and live price history.

Why we exist

Today, finding the right watch — and knowing what it should cost — requires bouncing between a dozen sites. Marketplaces show only their own listings. Price tools cover only a handful of references. Forum sales are invisible to most buyers. Crownly fixes that by giving every reference a single, comprehensive page.

Built for collectors

We are not a marketplace and we will never become one. Our job is to help you find, understand, and track watches — wherever they sell. We redirect to the sources that handle the transaction and authentication.

Status

Crownly is in early development. Today you can browse a curated set of iconic references with mock data. Real-time aggregation across eBay, Catawiki and Chrono24 partners is coming next.
