CrownBox: Watch Collection

CrownBox is a private home for your watch collection: catalog every piece, log who is on the wrist, keep the service and battery history, and give each watch your own value note.

Add a piece in minutes with its brand, model, reference, serial, case size, dial, bracelet, box and papers, and a photo. From there, CrownBox turns your entries into the numbers a notes app cannot: the whole box totalled against what you paid, cost per wear, who is really in rotation, and which battery or service is due next.

What You Get

• Piece catalog: specs, photo, purchase details, and notes for every watch
• Search, sort, and style filters: find any piece by name, dial, or style; sort by most worn, value note, or last worn
• Wear log: tap who is on the wrist today; one wear per piece per day
• Rotation coach: a daily suggestion for the longest-rested piece without overdue care, with one-tap logging
• Rotation stats (Pro): wears per week, most worn, pieces in rotation, and the shelf queens that have not left the box in 30 days
• Wear calendar (Pro): a month heatmap of your wrist time, month by month
• Cost per wear (Pro): what you paid, spread over the wears you logged
• Service and battery history: every entry per piece with shop, cost, and notes, plus a Due next list for coming batteries and services
• Care planner (Pro): overdue work and upcoming care grouped into 30-day, 90-day, and yearly horizons
• Value and insurance notes: your own value note per piece, insured values, and policy notes
• Insurance readiness (Pro): missing value notes and the recorded gap between your own value notes and insured values
• Documentation audit (Pro): open the box and immediately see which records still need a photo, reference, serial, box, papers, value note, or insured value
• 12 month care budget (Pro): forecast upcoming service spend from your due dates and the latest costs you recorded, while keeping unknown costs visible
• Collector briefing (Pro): see overdue care, upcoming care, missing record details, and idle pieces in one place
• Occasion picker (Pro): choose casual, work, formal, active, or travel and get a ready piece matched to the moment
• Ready lineup (Pro): see three rested watches ready to wear while pieces with overdue care stay out
• Wish list: the pieces you are hunting, with your target prices; landed wishes move into the box
• Piece comparison (Pro): compare two records side by side across specs, wear, value notes, cost per wear, and next care
• CrownBox Report (Pro): a clean PDF of the whole box plus a CSV of every piece
• Backup and restore (Pro): one file with the whole box, photos included; restoring adds what is missing and never deletes
• Travel-roll planner (Pro): select pieces by stable identity, keep packing state through renames, and retain a title snapshot if a selected piece is removed
• Syncs across iPhone and iPad with iCloud

About Value Notes

Every value in CrownBox is your own note, written by you. The app fetches no market prices, has no price feed, and makes no promise about what a watch would sell for.

Private by Design

No account of ours and no tracking. Your box lives on your device and in your private iCloud, and syncs across your iPhone and iPad.
