WristSignal
Watch price intelligence
Live on Chrome Web Store

Know if a watch is fairly priced — and find it cheaper.

WristSignal sits inside eBay, Chrono24, and Reddit and instantly signals whether a listing is a deal, fair, or overpriced — based on real sold data. Then its report shows you cheaper listings for the same watch and exactly how much you'd save. Selling instead? The same real-sold data tells you exactly what to list at.

Signal appears instantly

A price signal pops up showing whether the listing is a BUY, FAIR, WATCH, or SKIP versus the real market.

Save money on the same watch

The full report finds cheaper listings for the same reference — same box-and-papers tier — and shows exactly how much you'd save, plus comps, negotiation targets, and authenticity flags. $7 per report, or unlimited with a Session ($29) or Annual ($99) pass (fair-use limits of 30/50 reports per day).

More than a one-time price check.

Common questions.

Is WristSignal free?
Yes — the core price signal (BUY / FAIR / WATCH / SKIP) is free forever with no account required. Paid reports ($7 each, or unlimited with a pass — fair-use daily limits apply) unlock deeper analysis: cheaper listings for the same watch with the savings spelled out, live Chrono24 comparables, negotiation targets, and condition-adjusted pricing.
What are price-drop alerts, the watchlist, and the collection tracker?
Three free tools built into the extension. Set a price-drop alert on any listing and we'll email you when a matching watch hits your target price. Star references to your watchlist to track what you're eyeing in one place. Or add watches you already own to the collection tracker to follow their value against real 90-day sold data, with an optional monthly digest. All three are free and need only an email to send notifications — no account or login.
Can WristSignal find me a cheaper watch?
Yes — that's the heart of the paid report. When cheaper listings for the same reference are available right now, WristSignal surfaces them (up to three) with the exact dollar amount you'd save, matched on the same box-and-papers tier so it's a true like-for-like. Listings from another country are flagged because import VAT/duty may apply on top. If the listing you're viewing is already the best price we can find, the report tells you that too, so you can buy with confidence.
Can sellers use WristSignal too?
Absolutely. The same real-sold market data that tells a buyer if a price is fair tells a seller exactly where to list. Check your reference against the 90-day median and market range to price competitively without leaving money on the table, see what comparable watches actually sold for (not just asking prices), and use the collection tracker to know what everything you own is worth before you sell.
Where does the price data come from?
WristSignal pulls sold listing data from eBay, Reddit r/WatchExchange, and WatchUSeek's Sales Corner. Paid reports also include current Chrono24 comparables from global dealers.
How accurate is the price data?
Signals are based on real sold listings — not asking prices — pulled from eBay, Reddit r/WatchExchange, and WatchUSeek over a rolling 90-day window. Accuracy depends on market activity: popular references with dozens of recent sales have tight, reliable signals. Rarer references with fewer sales show wider ranges.
What if there's no data for a watch?
Niche or boutique references with limited market activity will show a "No Signal" result with the note "Insufficient market data." You can still generate a paid report, which runs a broader search across Chrono24 and WatchUSeek's full history.
Which browsers and sites are supported?
WristSignal works on Chrome and all Chromium-based browsers (Edge, Brave, Arc, etc.) on eBay, Chrono24, and Reddit WatchExchange. Safari is on the roadmap.
Does WristSignal work on mobile?
Not yet — WristSignal is a Chrome extension and currently works on desktop Chrome and Chromium-based browsers (Edge, Brave, Arc). Mobile browser extension support is on the roadmap.
Do I need an account?
No account, no password. The free signal works anonymously, and single reports require nothing more than a Stripe checkout. Session and Annual passes capture your email at checkout solely for activation and recovery — there's still no login to manage.
Session Pass or Annual Pass — what's the difference?
A Session Pass ($29) is for someone actively shopping right now: 90 days of unlimited reports — subject to a fair-use cap of 30 reports/day — then it ends. An Annual Pass ($99) is for collectors, enthusiasts, and dealers who browse listings year-round: 365 days unlimited, up to 50 reports/day. Both are one-time payments — no subscription, no renewals.
What if I clear my browser or switch devices?
Your pass is tied to the email you used at checkout. Visit wristsignal.com/recover (or use the link in the extension popup) and we'll email you a fresh activation link.
