Omega 265, 267, 284 Mainspring

Genuine Generale Ressorts Swiss-made replacement mainspring for Omega 265, 267 and 284 manual-wind movements. 

The Omega 265, 267 and 284 belong to Omega’s famous family of 30 mm manual-wind movements. These movements were produced during one of the most important periods in Omega’s history and can be found in a wide range of collectible vintage watches. Their robust construction and excellent serviceability have helped many survive for decades, making them popular movements for both professional watchmakers and hobbyists today.

If you’re servicing a vintage Omega 265, 267 or 284 movement, a high-quality replacement mainspring is important for proper fit and performance. A poorly made mainspring can cause fitment problems with the arbor or barrel and may not deliver the amplitude expected from a properly serviced movement. Here, there’s no mystery about what you’re installing: a branded mainspring made by Generale Ressorts, a leading specialist manufacturer of watch mainsprings.
