Longines L513

The Longines L513 is a manual-winding movement introduced in 2010 and based on the ETA 6497-2. It is not manufactured in-house by Longines but relies on the established ETA ebauche. The caliber remains in production and is used primarily in heritage-style watches within the Longines collection, particularly in models from the Flagship and Heritage lines that emphasize traditional craftsmanship.
