A private watch collection app, kept like a ledger.
Crown Quorum keeps the record of every watch you own: its papers, service history, condition, photographs, and documents. Private by default, and shared only when you choose.
What it keeps for each watch
Every watch, one record
Maker, model, reference, year, case and movement, with the papers, receipt, and provenance notes that belong to it.
Service history that survives
Dated service entries with the work done, the parts replaced, and the invoices behind them, so the history outlives the envelope it came in.
Condition, photographed
Condition notes and photographs over time, so you can see how a watch has been kept rather than remember it.
Documents in one place
Receipts, warranty cards, service papers, and valuations, stored with the watch they describe.
Who can see it
Private by default
No public profile and no listings. Your desk is yours alone.
Serials stay masked
Full serial numbers never appear in anything you share unless you choose to show them.
Share on purpose
Send a redacted packet to a buyer, an insurer, or family, with only what they need to see.
Not a marketplace
Nothing is listed, sold, or advertised from your records, and your data is never sold.
Common questions
- Why not keep my collection in a spreadsheet?
- A spreadsheet holds rows. The receipts, service invoices, and photographs end up somewhere else, and sharing the sheet shares everything in it. A desk keeps each watch's documents with its record and lets you share one redacted packet at a time.
- Does Crown Quorum value or authenticate watches?
- No. It keeps your records. Valuations come from a qualified appraiser, and authentication from the maker or a specialist.
- Can I ask about my collection from ChatGPT?
- Yes. You can connect your desk to ChatGPT to ask which records still have gaps. The connection only reads: it never changes, shares, or sends anything.
