Mainsprings by caliber

Which mainspring belongs in which movement?

For every caliber we show the mainspring dimensions – height, diameter, thickness and length – based on the Générale Ressorts mainspring catalogue (GR 2, 1974), transcribed and checked page by page. Where we have a mainspring with exactly these dimensions in stock, it is shown right next to it.

All information has been carefully checked but is provided without guarantee. Please check yourself before fitting that the mainspring fits, in particular height, diameter, thickness and length.
