Know what you own: every watch inventoried, rotated, and honestly valued — and any watch priced across the web before you buy it.
Built for collectors with real collections — five watches or five hundred, beater to grail. Founding access opens December 2026.
Welcome to the founding list. We'll write to you when founding access opens in December — founding members are first in, and first at the $29 lifetime window.
One email when we open, and the occasional build update. No spam, no selling your address — ever.
What It Does
Most collection apps were built for five luxury watches and a spreadsheet's worth of patience. Crownmark was built for the way a big collection actually lives.
Two photos — front and caseback — and the watch is identified and filed. You confirm the record; nothing is guessed into place.
Everyone has watches gathering dust. Crownmark keeps the whole collection in play instead of the same three on repeat.
No single made-up number dressed up as fact. Every value in Crownmark is a range, labelled by kind and dated.
See a watch you want? Photograph it. Crownmark identifies the exact reference, then sweeps online listings for that watch — not a near-match.
The Founding Offer
No subscription. Crownmark never rents you back your own inventory — the unlock is one payment, for the life of the product.
Your first 5 watches free — inventory, locations, rotation, and price checks. A real collection, not a demo.
The waitlist window: $29 once, lifetime. Unlimited watches, unlimited price watches, and the insurance-ready export. $39 for everyone after the window closes.
Founding members are the waitlist: first access when founding opens in December, first at the $29 window, and a direct line to shape what gets built next. Full data export is free at every tier, forever — your collection records are yours.
Giving it? Collectors get watches for Christmas. A founding lifetime unlock is a gift that fits the person who just got one — no size, no strap length, nothing to wrap but the news.
The Trust Strip
Your collection data is never sold and never shared with advertisers — in any form, at any price. Advertisers buy placement, never people.
Nothing is public unless you choose to share it — and shared views hide values. What you own, and what it's worth, stays with you.
Full export of your entire collection, at any tier, at any time. Your data leaves with you. Hostage data is the subscription industry's trick — not ours.
Questions
The honest answers, up front.
Founding access opens in December 2026 for the waitlist, as a web app you install straight to your phone's home screen. The app-store launch follows in January 2027. Join the founding list and you'll be first in — and first at the $29 lifetime window.
Both. Crownmark starts as a web app, so it runs on iPhone and Android from day one — no waiting for a store. In January it also arrives in the Apple App Store and Google Play, with the same account and the same collection.
No. Your collection is private by default. Nothing is posted, shared, or visible to anyone unless you deliberately create a share view — and share views hide values and private notes. Your data is never sold and never shared with advertisers.
No — and it never claims to be. Crownmark shows value ranges built from market data, each labelled by kind — asking prices, sold prices where available, and an insurance/replacement figure you control — with sources and dates shown. It's a guide for your own decisions, not an appraisal, a valuation opinion, or investment advice.
Three things: first access when founding opens in December, the $29 lifetime unlock window ($39 after it closes — one payment, no subscription), and a direct line — founding members' feedback and feature requests are read first and shape what ships next. The first 5 watches are free for everyone at launch; the unlock removes the cap.
A collector — one with 314 watches of his own, from beaters to grails, kept in stands, winders, and boxes and rotated daily. Crownmark is the system he built to run that collection, turned into an app: the photo intake, the locations, the rotation, and the price checks are the exact jobs he was doing by hand. It is built for large, mixed collections because it was born in one.
