Estate sales, auctions, dealer sites, classifieds, forums — Eo monitors them all, continuously, for the exact pieces you're hunting. The moment something surfaces anywhere, you know about it. Completely free.
The process
In plain words, as precisely as you like — "pre-1935 Gruen curvex in rose gold, honest dial, under $2,000" is exactly the kind of thing Eo understands.
Auction houses, estate sale listings, dealer inventories, marketplaces, and collector forums — scanned around the clock, worldwide, including the badly-titled listings keyword alerts always miss.
A curated alert the moment a real match appears — with condition notes, price context against comparable sales, and a straight assessment of whether it's actually the piece you described.
Capabilities
The best deals are the mislabeled ones — "old watch from grandpa's drawer" doesn't say Gruen anywhere. Eo matches on photos and descriptions, not just titles, which is where the finds live.
Regional auction houses, estate sale companies, dealer sites, specialty forums, and overseas marketplaces most collectors never check — one watchlist covers all of it.
Every alert comes with red flags called out — repaint, marriage, reproduction, missing provenance — and where the asking price sits against real comparable sales.
Want it? Eo can contact the seller, ask for the photos you'd ask for, negotiate within your ceiling, and arrange shipping — you stay anonymous until you choose not to be.
