Frequently Asked Questions
How accurate is AI watch authentication?
Our AI authentication analyzes 15+ visual checkpoints with over 90% accuracy on supported brands. While AI authentication is an excellent first-pass screening tool, we recommend pairing it with a professional watchmaker inspection for high-value purchases. The AI excels at catching common tells that counterfeiters frequently get wrong, such as font spacing, cyclops magnification ratios, and lume marker alignment.
Can AI detect a super-clone or high-quality replica watch?
AI authentication is highly effective against the vast majority of counterfeits, which account for roughly 90% of fakes on the market. Super-clones present a greater challenge for any authentication method, including human experts. Our AI is trained on known super-clone patterns and continues to improve as new counterfeits appear. For watches valued above $10,000, we recommend combining AI screening with an in-person inspection.
Which watch brands can be authenticated?
Grailr currently supports authentication for Rolex, Omega, Patek Philippe, Audemars Piguet, Cartier, TAG Heuer, Breitling, Panerai, IWC, Tudor, and Hublot. We are continuously expanding coverage. Rolex authentication is our strongest capability due to the volume of training data available.
Is online watch authentication really free?
Yes. Every Grailr user gets 3 free scans per month, and each scan includes both identification and an authenticity confidence report. If you need unlimited authentication scans, our Collector plan ($9.99/month) removes all limits and provides detailed checkpoint breakdowns.
What photos should I upload for the best authentication results?
For the most accurate results, upload a well-lit photo of the watch dial taken straight-on. Additional photos of the caseback, crown, bracelet clasp, and side profile significantly improve accuracy. Avoid harsh shadows or reflections on the crystal. Natural daylight produces the best results.
