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 — against what buyers actually paid where we have sold data, and against what sellers are asking where we don't. We always tell you which. Then its report shows you cheaper listings for the same watch and exactly how much you'd save. Selling instead? The same data tells you what to list at.

Three seconds to a smarter price.

Install once. WristSignal runs automatically on watch listings across eBay, Chrono24, and Reddit.

1

Browse listings normally

Open any watch listing on eBay, Chrono24, or Reddit. WristSignal detects the reference number and asking price automatically.

2

Signal appears instantly

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

3

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. $1 per report, or unlimited for 30 days with a Session Pass ($10) — fair-use limit of 30 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 ($1 each, or unlimited with a Session Pass — a fair-use daily limit applies) 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 current market 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 market data that tells a buyer if a price is fair tells a seller where to list. Check your reference against the median and market range to price competitively without leaving money on the table, look at the comparable listings behind that number, and use the collection tracker to know what everything you own is worth before you sell.
Where does the price data come from?
Completed sale prices come from Reddit r/WatchExchange. Current asking prices come from eBay, and in paid reports from Chrono24 dealers worldwide. eBay retired its public sold-listings API, so we can't show you eBay sold prices — what we label an asking price is exactly that.
How accurate is the price data?
It depends on what data exists for your reference, and we tell you which you're getting. Where we have completed sales — a rolling 90-day window from Reddit r/WatchExchange — the signal measures the ask against what buyers actually paid. Where we don't, it measures against current asking prices on eBay and Chrono24, which run higher because they're what sellers hope for rather than what anyone paid. Every median on screen says which it is. Popular references with plenty of recent sales give tight signals; rarer ones 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 searches Chrono24's dealer listings directly instead of waiting on the background fill the free signal uses.
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. The Session Pass captures your email at checkout solely for activation and recovery — there's still no login to manage.
Single report or Session Pass — which should I buy?
Buy a single report ($1) if you're deciding on one watch. The Session Pass ($10) is for someone actively shopping: 30 days of unlimited reports, subject to a fair-use cap of 30 reports/day. It pays for itself at ten reports. 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.
