Watch Serial Number Lookup
Zodiac, a Swiss brand best known for the Sea Wolf diver and now owned by Fossil Group, engraves or stamps a 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.
Zodiac typically stamps or engraves the serial number on the case back, often alongside the model reference. Vintage Zodiac pieces may have the number on the movement instead.
It uniquely identifies your individual watch. Zodiac does not publish a public consumer serial-to-date decoder, so serial-number conventions vary by model, era of ownership, and production period — verify specifics through your documentation or Zodiac customer service.
No, not by itself. A serial number that looks correct doesn't rule out a counterfeit or misrepresented watch, particularly for popular vintage models like the Sea Wolf.
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.
Zodiac has changed ownership multiple times over its history and is now part of Fossil Group, which affects how consistently serial-number and documentation conventions apply across different production eras. Because serial-number conventions vary by model and production period, verify a specific number through your original documentation or Zodiac customer service rather than an unofficial guide.
Usually on the case back, alongside the model reference. Some vintage pieces have the number on the movement instead.
Zodiac doesn't offer a public serial-to-date lookup, and conventions vary given the brand's changes in ownership — Zodiac customer service or a vintage specialist can help verify specifics.
No, not by itself, particularly for popular vintage models. Verify through documentation and, if uncertain, a specialist inspection.
