Overview

Dials is a reference catalogue of wristwatches: every model described to the same specification, with live marketplace listings matched against it. This documentation explains the thinking behind the catalogue, where its data comes from, and how to read all of it programmatically.

What is here

• Philosophy: why the catalogue exists and the principles it is built on.
• Where the data comes from: how the catalogue and the listings are sourced, matched and kept clean, and the shape of the catalogue and the listings.
• The API: everything the catalogue knows, as JSON, with no key and no account, plus the interactive reference generated from the OpenAPI document.
