Omega calibre / caliber and mainspring reference table
About this reference guide
This database has been compiled from historical Générale Ressorts (GR) reference information and other available watchmaking data.
Vintage watch-parts catalogues can contain discrepancies, revisions and alternative references, and individual movements may have been modified during previous servicing. The information provided here should therefore be used as a reference guide and cannot be guaranteed to be 100% accurate.
Before ordering or installing a mainspring, we recommend confirming the Omega calibre / caliber and, where possible, comparing the dimensions and type with the original mainspring.
