Note: We have transcribed this information to the best of our knowledge from the Générale Ressorts mainspring catalogue (GR 2, 1974). 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.
