The required gates
Deal detection starts only after the listing has enough identity and price data to compare like with like. Thin or ambiguous comp pools are treated as missing evidence, not permission to make a stronger claim.
- Seller body text is present
- The asking price is explicit
- The watch reference has sufficient comp data
- The Collector plan or trial is active and Deal Alerts are opted in
- The user's optional brand filter allows the listing
What below-market means here
The comparison uses recent observed listings for the same normalized reference. Condition, completeness, service history, year, bracelet configuration, taxes, and authenticity can still explain a price difference. The result is a screening signal, not a valuation certificate.
The alert shows the listing and available comp context so the buyer can inspect why the price looks unusual instead of relying on a black-box badge.

Frequently asked questions
Which plan includes Deal Alerts?
Deal Alerts come with the Collector plan ($20/mo or $200/yr) and every 14-day free trial. Users turn them on.
Will every cheap listing trigger an alert?
No. Missing seller text, missing price, thin comps, failed brand filters, or inactive permission prevent delivery.
Is a Deal Alert an appraisal?
No. It is a data-backed screening signal from observed listings, not a professional appraisal or authenticity opinion.
Can I limit deal discovery by brand?
Yes. You can apply an optional inclusion or exclusion brand filter.
