Build a lasting record of every watch you own. Heirline is a private watch collection organizer for collectors who care about service history, provenance, valuations, documents, and the stories behind each timepiece. Keep everything structured for long-term ownership without creating an account or giving your collection data to us. YOUR COLLECTION, DOCUMENTED - Catalog brand, model, reference, serial, caliber, dimensions, purchase details, status, notes, and complications. - Add a profile photo and detail photos, then zoom and swipe through the full gallery. - Sort and filter your collection while keeping sold, inherited, or passed-down pieces in context. SERVICE HISTORY THAT LASTS - Record each watchmaker, service date, cost, work performed, parts replaced, and report attachment. - Track overhauls, regulation, polishing, crystal work, and water-resistance testing. - Use brand-based interval suggestions and optional service reminders. PAPERS, VALUE, AND PROVENANCE - Track box-and-papers completeness with the BPNN model: Box, Papers, Numbers, and Notes. - Store warranty cards, receipts, certificates, appraisal documents, and service reports. - Record source-attributed valuations and view each watch's value history over time. - Generate six PDF reports, including an Insurance Schedule Pack and Provenance Pack. PRESERVE THE STORY - Record who should receive each watch. - Write a personal letter, ownership story, and care instructions. - Keep milestones and memories in the Wrist Journal. - Create an Estate Transition Booklet for your family records.
