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 the camera, no flash glare.
- Dial close-upStraight on, in daylight or diffuse light. Hold the phone about 10 cm away and let it focus; closer than that it cannot. If the phone has a macro mode, use it.
- CasebackStraight on, the whole caseback in the frame, no reflections.
- Clasp / buckleOpen the clasp so the inner stampings show; remove any protective film first.
- Engravings / serialThe engraved ring inside the dial edge, or the serial between the lugs, straight on. About 10 cm away, let the phone focus, or use its macro mode.
- Date windowStraight on, the date and its magnifier in focus: about 10 cm away, or the phone's macro mode. Skip if there is no date.
- Side / case profileCrown side, level with the case, crown and its guards in focus.
- MovementOnly if it shows through a display back or with the caseback off. This is the view that gives a high-grade copy away, so make it the sharpest one: about 10 cm away, let the phone focus, or use its macro mode.
Your photos are used only for the authentication you request.
