Know when to stop bidding. Instant auction analysis for any watch. Every bid you place without data is a gamble. Watch Advisor analyzes any "Loupe This" auction listing in seconds using recent data to let you know if you are underpaying or overpaying. Watch Advisor uses live market data from eBay sold listings, Bob's Watches, Chrono24, and recent auction results from Phillips, Christie's and Sotheby's. Open a listing, click the icon, get the answer. Watch Advisor works best on Loupe This. Also works on any other platform with manual entry. HOW IT WORKS Before you bid, know what the watch is actually worth. Open any Loupe This auction page and click the Watch Advisor icon. The extension automatically reads the listing grade and inclusions. No manual input needed. Get a full market analysis in seconds. WHAT YOU GET • UNDERPAYING / FAIR / OVERPAYING verdict: the main answer, front and center • Stop Bid At: the maximum price you should pay before walking away • Deal gauge: visual meter showing where the bid sits vs fair market value • Data Confidence rating: tells you exactly how reliable the analysis is and which sources were used • Investment outlook: GRAIL / STRONG BUY / ACCUMULATE / HOLD / AVOID • Price trend: is this reference appreciating, stable, or correcting? • Full market range: adjusted for the exact condition and inclusions of this listing • Condition and inclusions impact: what missing box or papers actually costs on this specific reference • Comparable watches: 3 alternatives worth considering at a similar price • About this watch: history, movement, and why collectors care • Recent analyses: your last 10 lookups saved for comparison CONDITION-AWARE PRICING Watch Advisor uses the Loupe This V-grade system (V 10 through V 7.5) and factors in exactly what is included: box, papers, extra links, service history, warranty card. A V 8.5 watch with no papers is priced differently from a V 9.5 full set. The analysis reflects that. DATA INTEGRITY Every price data point is validated against 7 safety gates: exact reference match, case material, condition equivalence, data recency, and source reliability. The extension will tell you when data is insufficient rather than give you a confident wrong number. COST Watch Advisor requires an Anthropic API key, free to obtain at console.anthropic.com. Each analysis costs approximately $0.01 to $0.03. A $5 credit gives you hundreds of analyses. There is no subscription fee. PRIVACY Your API key is stored locally in Chrome only. No data is collected or stored by this extension. Bid with confidence and know exactly when to stop before the hammer falls. Built by Goldszmidt.
