Not every watch needs the same check, but only one of these is still checking after the sale is over. See exactly how a serial search, a photo screen, a marketplace program, an appraisal, and an in-person authentication compare.

Every option below does something real. Only one does the whole job: a permanent public registry entry, a stolen-watch flag that never expires, and an independent expert who signs their name to the record. That is Watch Safe. Everything else here handles one piece of the problem and stops.

| Service | How the watch is checked | Permanent public record | Stolen-watch flagging | Physical tag on the watch | One-time or ongoing | Price | Turnaround |
|---|---|---|---|---|---|---|---|
| The complete registryWatch Safe | In-person physical inspection by an independent expert authenticator, who signs the record under their own name. | YesYes. Every authenticated watch gets a permanent public registry entry that stays with the watch, not with the owner. | YesYes. Anyone can check a serial number against the registry for free, and a reported stolen watch is flagged for every future search. | No. The permanent link is the registry entry and blockchain-anchored certificate, tied to the serial number already on the watch. | The registry entry is permanent. Later changes of hands are recorded with a $49 ownership transfer. | $250 to $1,199 one time, set by the watch's declared value tier. | Scheduled directly with the authenticator; the registry entry publishes when the inspection is certified. |
| eBay Authenticity Guarantee | Multi-point physical inspection at an authentication center, in the middle of an eBay sale. | None | None | A security tag is attached for shipping, plus the NFC-enabled card. | One transaction. The check exists because a sale is happening on eBay. | Free for buyer and seller at $2,000 and up; $80 as an optional add-on from $500 to $1,999.99. | Built into eBay's shipping flow; the watch routes through the inspection center between seller and buyer. |
| Chrono24 | Optional: Chrono24 Certified adds a physical check by Chrono24's in-house watchmakers at the point of sale. Most purchases rely on the payment window and return rights instead. | None | None | None described. | Per transaction. Payment is held in Chrono24's escrow account for 14 days after delivery from dealers, or 7 days from private sellers. | Buyer Protection is free in most cases; Chrono24 Certified is a $249 option. | The Certified check happens between sale and delivery, inside Chrono24's shipping flow. |
| The Watch Register | None. It is a database check against reported losses, not an inspection of the watch. | None | YesYes, the core product: over 100,000 lost and stolen watches on the database. | None. | A registration stands until the case resolves; a 5% location fee applies on a successful recovery. | £10 plus VAT per search for private individuals; £15 plus VAT to register a lost or stolen watch. | A search is a lookup against the database, not an inspection. |
| LegitApp | Photo-based: uploaded photos reviewed by an AI system plus at least two senior authenticators. | None | None | None. | Per item, per check. | From $15 per watch, varying by service level and brand. | Selectable, from 10 minutes to 12 hours. |

The most expensive mistake is asking one kind of proof to answer a question it was never designed to answer.
No. An appraisal assigns a value, usually for insurance, and assumes the watch is what it appears to be. Authentication establishes whether the watch is genuine and correct. A careful seller of a valuable watch often needs both, but neither substitutes for the other.
The check belongs to the platform and the transaction it happened in. What the buyer keeps varies by program, and when the watch sells again somewhere else, that next buyer generally starts from zero. A public registry entry works the other way: it attaches to the watch itself and any future buyer can look it up.
No. A registry can flag a serial number so that anyone who checks finds the report, and that flag is what gives a stolen watch nowhere quiet to go. But no database physically prevents a private sale. The value of a theft flag grows with the number of people who check before they buy.
An independent expert authenticator from a select network, in person, with the watch in hand. Watch Safe itself does not authenticate anything: it records the inspection, publishes the permanent registry entry, and keeps the ownership history attached to the watch. The authenticator who certified the watch is named on the record they signed.
Because a watch outlives every transaction it passes through. A one-time check answers today's question for today's buyer. A permanent registry entry means the inspection, the ownership history, and any theft report stay attached to the serial number for the next owner, and the one after that. That is the difference between an authentication event and an authentication record.
Search the public registry for an existing record or theft flag. If you need a new in-person authentication, see the cost first and find an independent expert near you.
