Discover your watch with Grailr. Take a clear photo or choose one from your library. Grailr technology helps identify the brand, model and reference, then provides watch details and indicative value estimates. SCAN & IDENTIFY Explore the likely identity, materials, movement type and visible condition of a watch. Review the confidence level and supporting details in each result. Photo-library scanning remains available when camera access is turned off. EXPLORE ESTIMATED VALUES See an indicative value range alongside available eBay listing data. Listing prices are asking prices, not evidence of completed sales. Results depend on the image and available information; Grailr does not authenticate watches or provide a professional appraisal. REVISIT YOUR SCANS Keep your scan history in one place and open saved results whenever you want to revisit a watch. SEARCH THE DATABASE Collector and Dealer plans include manual search by brand, model or reference number. Explore the specifications and pricing information available for matching watches. MARKET SIGNALS Dealer plans include market signals based on available pricing data, helping you explore changes and compare opportunities. These signals are informational and are not financial advice. CHOOSE YOUR PLAN • Free: 3 scans per month with watch identification and basic value estimates. • Collector: Unlimited scans, manual database search and additional market information. • Dealer: Collector features plus the market signals dashboard.
