The Opportunity
The watch market rewards speed — and punishes mistakes.
Most people lose not because they lack taste, but because they lack instant context. Patina gives you that context on demand.
Misidentified watches
Wrong reference, wrong valuation. One misread detail can cost thousands.
Slow research
Hours spent cross-referencing forums, listings, and guides before a single decision.
Hidden red flags
Fakes, franken-watches, and mismatched parts hiding in plain sight.
Bad pricing comps
Asking prices lie. Without real sales data, you're flying blind.
How It Works
From scan to sold in minutes.
Scan & identify
Snap a photo. Patina identifies the brand, model, reference, and year — with a full description.
Price with confidence
See real buy and sell ranges with eBay fees factored in, so you know your walk-away number.
List in one tap
Patina writes the title, description, and specs — and publishes straight to eBay.
Track the outcome
Every sale lands in your collection with profit, ROI, and days on market.
Watch Health
Hear how it ticks.
Rest your iPhone on the crystal and Patina listens to the movement — measuring rate, beat error, and beat rate like a timegrapher. Catch a watch that needs service before you buy it, and prove yours runs strong when you sell.
No extra hardware. Just your iPhone’s microphone.
Pricing Intelligence
Know your numbers before you negotiate.
Every scan comes with live market context: what to pay, what it sells for, and how condition moves the price — with a confidence rating on every estimate.
