Where to Find the Longines Serial Number
Your Omega watch’s serial number is typically a 5- to 9-digit number that uniquely identifies your timepiece.
For watches covered by this tool (1870–1980), the serial number is typically located on the movement – the internal mechanism of the watch.

What Is Not a Serial Number
Avoid confusing the serial number with these:
- Model/reference numbers (e.g., L2.755.4.78.6) – These identify the design, not the individual watch.
- Case numbers – Often longer and located on the outside, unrelated to production year.
- Bracelet or clasp codes – These relate to the strap, not the watch body.
Disclaimer: This tool provides approximate production dates. For official authentication, consult an authorized Longines service center.
