How it works
From photos to an evidence-backed verdict.
Loupe is built around one idea: a verdict is only as strong as the photos behind it. Our guided flow captures the angles that matter, and the report shows findings per component — so you see why, not just what.
1 — Tell us the watch
Start with the brand and model, and add the reference number if you know it — you'll find it engraved between the lugs or on your papers. Don't know it? Leave it blank: we identify the reference from your photos and ask you to confirm. Authentication is reference-specific: a Submariner 126610LN is checked as exactly that reference, not "Rolexes in general."
2 — Capture guided photos
The flow walks you through eight views — full front, dial close-up, caseback and clasp, plus the engravings, date window, side profile and movement where visible. Four are required; each additional view gives the analysis more evidence. Every slot shows an example photo and a one-line tip.
3 — AI analysis
Your photos are compared view-by-view against verified examples of your reference, and checked against a curated knowledge base of documented tells — the details counterfeiters most often get wrong, from engraving depth to clasp stampings.
4 — Read your verdict
You receive a confidence score and per-component findings in plain language. Where the evidence is insufficient, the report says so — an honest "not assessed" beats a confident guess.
The photos we'll ask for
- Full frontWhole watch, dial facing camera, no flash glare.
- Dial close-upAs close as focus allows on text and markers.
- CasebackFill the frame; engravings legible.
- Clasp / buckleOpen the clasp; inner stampings visible.
- Engravings / serialThe engraved ring around the dial edge, or the serial between the lugs.
- Date windowStraight-on close-up of the date and its magnifier. Skip if there's no date.
- Side / case profileCrown side, showing case thickness and the crown logo.
- MovementOnly if visible through an exhibition back.
Your photos are used only for the authentication you request.
