Patina AI - Scan, price, track, and sell watches from your phone

Patina AI is a mobile workspace for watch dealers, resellers, and collectors. Scan a watch in about 20 seconds to identify a likely reference, review real market ranges and comparable sales, model a profitable purchase price, track inventory and service costs, create eBay listings, and measure net profit. The catalog covers more than 50,000 references and supports over 1,100 watch professionals and collectors.

Hi Product Hunt, I’m Yucheng, founder of Patina AI. Evaluating and selling a watch often means jumping between reference databases, market listings, spreadsheets, inventory tools, and sales channels. I built Patina AI to bring that workflow into one mobile workspace. Take a photo and Patina suggests the reference and specifications in about 20 seconds. From there, you can review market ranges and comparable sales, calculate a purchase price around your target return, track acquisition and service costs, generate an eBay listing, and see the net profit behind each sale. The built-in timegrapher can also estimate rate, amplitude, and beat error with the iPhone microphone. Our catalog now covers more than 50,000 watch references and supports over 1,100 dealers, collectors, and resellers. I’d love feedback from watch professionals and collectors. Which part of the buying, inventory, or selling workflow takes the most time today?
