Longines 19A, 19AD mainspring

Genuine Generale Ressorts Swiss-made replacement mainspring for vintage Longines 19A and 19AD automatic movements.

The Longines 19A family dates from an important period in the development of automatic wristwatches and can still be found in collectible vintage Longines watches today.

When servicing a vintage Longines movement, mainspring quality and dimensional consistency matter. There’s no mystery about what you’re installing: GR3196X is a branded Swiss mainspring made by Generale Ressorts, a leading specialist manufacturer of watch mainsprings.

Is GR3196X compatible with the Longines 19A and 19AD?

Yes. GR3196X is listed as a replacement automatic mainspring for Longines calibers 19A and 19AD. Because vintage movements may have undergone previous repairs or parts substitutions, compare the existing mainspring and barrel configuration before installation.
