Longines L636

The L636 is an automatic movement manufactured by Longines, based on the ETA 2836-2. It features a day-date complication displaying the day of the week and date in a single window. Introduced in 2008, it remains in production and is used across Longines collections requiring a reliable day-date function. The movement is not in-house, relying on the established ETA architecture rather than a proprietary Longines development.
