Build a Photo Pre-Screen Tool for Watch Resellers

1. 1

   Design the claim before the model

   This product flags risk signals; it does not authenticate. That sentence must shape everything: output language ('three features inconsistent with reference examples'), pricing, terms of service, and marketing. A tool that implies certainty inherits the cost of every fake it misses; a tool that triages honestly gets to exist.

2. 2

   Start with a few models where volume lives

   A handful of watch models dominate secondhand volume and counterfeit attention. Deep reference coverage of those (dial printing, fonts, engravings, clasp details, movement decoration) beats shallow coverage of a thousand models, and it matches what your dataset can realistically support.

3. 3

   Build the dataset with dealers, not scraping

   Partner with dealers and authentication services for labeled photos of genuine and counterfeit examples; their archives are the moat no scraper assembles. Revenue share or free access in exchange for data builds both the model and the distribution at once.

4. 4

   Output findings a human can check

   Show the user what the tool saw: the reference detail, the submitted photo's version, side by side. Explainable output turns the tool into an education layer, reduces blind trust, and keeps the human decision where it belongs. Photo quality guidance (what to shoot, in what light) is half the product's value.

5. 5

   Route the big decisions to humans

   Above a price threshold or below a confidence threshold, the correct answer is 'get this professionally authenticated,' with a referral to established services. The pre-screen and the professionals are complements: you catch the cheap obvious fakes, they earn the final word, and the referral relationship legitimizes you.

6. 6

   Charge per check with reseller volume tiers

   Casual buyers pay per screening at impulse pricing; resellers screening sourcing candidates weekly buy volume packs. Marketplace sellers may also pay to attach a screening report to listings, clearly labeled as a pre-screen, as a trust signal that moves inventory.
