Watch Serial Number Lookup
TAG Heuer, known for the Carrera, Monaco and Aquaracer lines, engraves a unique serial number on every watch. Here's where to find it and how to check it.
Watch checks & theft reports
A database check is not proof of authenticity or ownership.
TAG Heuer typically engraves the serial number on the case back. It's also printed on the warranty card issued by an authorized dealer at purchase.
It uniquely identifies your individual watch and, matched with your warranty card, supports a claim of authorized-dealer purchase. TAG Heuer does not publish a public serial-to-date decoder for consumers, so serial-number conventions vary by model and production period.
No, not by itself. TAG Heuer is a widely counterfeited brand at multiple price points, and a plausible-looking serial number engraved on a fake case is not evidence the watch is genuine.
Check the case back, between the lugs, the rehaut, the movement, the warranty card and the original box or papers. Locations vary by brand — see the brand guides below.
Most brands also stamp a separate reference or model number. Together, the two numbers identify the exact watch far better than either alone.
Run the serial number through our stolen-watch database to check whether matching watch information has been reported stolen.
A match or a clean result is one data point, not a verdict — compare the watch's details carefully either way.
For a significant purchase, pair your search with authentication from the manufacturer, an authorized dealer or an independent watch specialist.
TAG Heuer produces watches across a wide range of price points, from accessible quartz chronographs to higher-end mechanical Carrera and Monaco models, which makes it a frequent counterfeit target across the board. Because serial-number conventions vary by model and production period, verify a specific watch through an authorized TAG Heuer boutique rather than an unofficial guide.
It's engraved on the case back and printed on the warranty card issued by the authorized dealer at purchase.
Yes, across multiple price points and collections, which is why documentation and, for higher-value models, professional authentication matter for used purchases.
No, not by itself — a fake case can be engraved with a plausible serial number. Verify with an authorized TAG Heuer boutique if you're not fully confident.
Take the serial number from the case back and search it through StolenWatchX's stolen-watch database before you buy or accept the watch.
