Getting a clear photo of engravings and stamps is the most important step for accurate identification. Markings on watches and jewelry are often tiny and can be difficult to capture with a phone camera.
AI analysis can identify common marking patterns and provide educational context, but it has important limitations:

Upload clear photos of your watch or jewelry markings. The AI analyzes visible engravings, stamps, and codes, then compares them against known marking patterns to provide educational observations about what they might mean.
No. This tool provides educational guidance only. It cannot authenticate watches or jewelry. For authentication or valuation, always consult a qualified watchmaker, jeweler, or authorized service center.
The tool can analyze serial number engravings, case-back stamps, bracelet clasp codes, hallmark purity marks (like 925 or 750), assay office symbols, maker's marks, water resistance ratings, and other common watch and jewelry markings.
Use good lighting and hold the camera close to the marking. Avoid glare by angling the light source. Take multiple photos from different angles. For case-back engravings, a macro lens or your phone's zoom can help capture fine detail.
Photos are sent to an AI model for analysis and are not stored permanently. We do not share your images with third parties. See our privacy policy for full details.
