Buying watches on eBay: what $2,000 authentication misses

Does eBay authenticate watches, and at what price?

Yes, at two price points, in the Wristwatches and Pocket Watches categories. From $2,000 up it's automatic and free. Between $500 and $1,999.99, select watches let you add it at checkout for $80 plus tax. Under $500 you can't get it at all. The watch has to be sold on eBay.com by a seller in the US (or an eligible seller in Japan) to a buyer in the continental US, so a UK seller's listing won't carry it.

What you get is an inspection after the sale. The seller ships the watch to an authentication center, eBay's partner checks that it's authentic and matches the listing, and then it comes to you. If it fails, you're refunded. eBay's watch authentication page also lists two things the inspection leaves alone: the authenticator "does not verify the timekeeping accuracy of your watch," and it "will not inspect any aftermarket documentation of provenance for authenticity."

Some watches can't go through the program at any price. eBay's Authenticity Guarantee help page shuts out smart watches, watch parts and watch accessories. It also shuts out customized watches: "A watch is deemed to be customized if the original brand parts have been replaced with non-brand parts or parts not original to the model or era, or if components have been modified from the original design." Vintage watches get some slack. A replaced strap, bracelet, crystal, spring bars or gaskets won't disqualify one, and a non-original part the maker no longer produces may be allowed too.

That definition is where watch buying gets expensive. eBay's inspection is there to tell you the watch is genuine. Whether every part on it belongs to that model and that era is a separate question, and in watches it's usually the one that sets the price. If you're buying in another category, our table of every Authenticity Guarantee category has its thresholds and exclusions.

Four terms in watch listings that change the price

None of these four terms means fake, and every one of them moves the price. A seller who knows exactly what they have can pick the vaguest one that's still true.

The frankenwatch is the one that costs buyers the most. Picture a vintage Submariner, reference 1680, with a dial and hands taken from a different reference, sold as an untouched example. Every part is real Rolex. A dial "not original to the model or era" can make it a customized watch under eBay's wording, which leaves two ways it can go at the authenticator: it's turned away as customized, or it gets through on the strength of its genuine parts. Neither result tells you the watch is original, and original is what the price assumed.

Superfakes, and why a passed check proves so little

A superfake is a counterfeit built to survive the usual checks, often with a clone movement (a copy of the real movement) inside. The tells in buying guides are public, so the people who make superfakes know them too. So when a watch fails a check, that's strong evidence against it, and when it passes one, it hasn't proved much at all.

The old line that fakes tick and real watches sweep is the clearest casualty. A clone automatic is still a mechanical movement, so its seconds hand sweeps too. A hand that ticks once a second on a watch sold as an automatic usually means there's a quartz movement inside, and that's worth walking away over. A sweeping one tells you very little now.

Some faults are enough to walk away on their own: the wrong magnification over the date, a serial that doesn't match the card, a movement that reference never used. The famous passes, like the laser-etched crown, the engraved inner bezel ring and the date font, are the ones a good fake is built to copy. Passes only start to add up when they come from different parts of the watch: the optics, the movement, the engraving and the paperwork. Four photos of the same dial is one check taken four times.

What you can check from the listing photos

On a Rolex, the Cyclops lens over the date magnifies about 2.5 times, so the date nearly fills the window and sits in the middle of it. Many fakes use a weaker lens, about 1.5 times or less, so the date floats with space around it and is often off-center. Compare it with the brand's own photo of that reference at the same zoom.

Engraving on a caseback, an inner bezel ring or a clasp should be crisp and evenly deep. Shallow, blurred or wavy laser engraving is a tell you can often see in a decent listing photo.

Then count what's missing, and ask for the caseback, the inside of the clasp, the inner bezel ring, the lugs and, on a display back, the movement. Ask for one more: the watch next to a handwritten note with today's date and the seller's eBay user ID. A seller working from somebody else's pictures can't send you that one.

A slow-motion video of the seconds hand stands in for equipment you don't own. Every movement beats at a set rate, and a fake's movement often beats at a different rate from the one it imitates. Omega's 8500 family of Co-Axial calibers (a caliber is a movement model), for example, runs at 25,200 vibrations an hour, which works out to seven ticks a second. A clone built to 28,800 an hour, a common modern rate, ticks eight times. Not every Omega caliber runs at 25,200, though, so look up the caliber in that exact reference before you count. Then ask the seller for the video, slow it down and count the ticks in one second. If the count is wrong for that caliber, that settles it. A right count doesn't clear the watch, because a good clone runs at the right rate too.

Book the watchmaker before the watch arrives

Some checks need the watch in your hand, so line them up before delivery. Under eBay's Money Back Guarantee you get 30 calendar days after delivery, or the seller's own return window if that's longer, to ask for a return when the watch isn't as described. A watchmaker who can't see you for three weeks eats most of that.

A timegrapher is the machine watchmakers use to read a watch's rate, amplitude and beat error, and it gives you the beat rate directly, so nobody has to count ticks. An authenticated watch still needs this, because eBay's inspection skips timekeeping.

The magnet check is for one kind of watch. Omega's Master Chronometers are certified to resist magnetic fields of 15,000 gauss, so a genuine one keeps time after a strong magnet, and a fake without that protection can come away running fast or not at all. On any other watch, a strong magnet can leave it magnetized and running badly until a watchmaker fixes it. So try it only after delivery, inside your return window, on a watch whose reference number Omega lists as a Master Chronometer, and never ask a seller to do it for you.

Having a watchmaker open the caseback settles most arguments, and the bench fee is small next to a four-figure watch.

None of this helps you get your money back unless the listing promised what you're checking. A service dial or a swapped bracelet is hard to call "not as described" unless the listing said the watch was original, so ask the seller to confirm "all original parts" in eBay messages before you buy. Then pick a seller whose return policy gives you room for all of this. There's a catch on authenticated watches, from eBay's own watch page: a watch listed as new, from a seller who takes no returns or whose window has closed, is final sale once it passes, and you can't send it back. What eBay's Money Back Guarantee covers is the floor under any seller's policy.

Serial numbers, box and papers

Four sets of numbers have to fit together: the case serial, the movement's numbers, the codes on the bracelet or clasp, and the warranty card. They won't be the same digits. Most brands number the case and movement separately, and on many bracelets the clasp code is a date code. What has to hold is that the card carries the case's serial, and the movement and clasp belong to that reference and that era.

The case and movement numbers are stamped or engraved by the manufacturer, and a frankenwatch can fail there, because its parts came from different watches. A clasp code from a different decade than the case means the two were put together later. A warranty card only counts if it matches. One with a different serial from the case, or with the serial left blank, adds nothing. Boxes and cards can be bought on their own, so a "full set" can be put together from three purchases.

Papers get forged like anything else, and eBay says its authenticator won't inspect aftermarket provenance documents. On r/Watches, a buyer described a TAG Heuer that came through eBay's authentication with a forged card. That's one account and we can't confirm it. Still, the guarantee lowers your risk. It doesn't tell you the watch is original. A matching card never outranks a physical check that failed.

Pricing a watch when the cheapest one might be wrong

Chrono24, the big watch-only marketplace, is worth a search for the same reference. Read its prices the way you'd read eBay's: they're what sellers are asking, not what anyone paid.

To find out what a watch actually sells for, two places help:

• WatchCharts collects price data on past watch listings from forums, Reddit and eBay, searchable by reference number, and rates current listings as a good, great or fair deal. Looking backward like that is something FindersKeepers can't do, because we have no sold data. It has a free tier and a paid one.
• eBay's sold items filter is the free way to see what buyers paid on eBay itself. eBay doesn't say how far back it reaches, and the figure sellers pass around is about 90 days, so check the date on the oldest result before you treat it as the whole picture.

Whichever you use, search the reference number. "Submariner" and "16610" bring back different sets of watches, and only the second is comparable.

In most categories the cheapest listing on the page is the find. In watches it's a question. A frankenwatch, a redial (a dial that's been refinished or repainted) and a watch with an aftermarket bezel all sell for less than an untouched example, and in photos they all look like one. When a genuine reference is priced well below the others, there's a reason, and your job is to find it before you pay.

FindersKeepers flags listings priced well under similar ones for sale on the same eBay site, and on a watch that flag is where your checking starts.
