A. Lange & Söhne L041.2

The L041.2 is a manual-winding movement manufactured by A. Lange & Söhne, introduced in 2007 as part of the L0xx family. It displays a second time zone using a city ring that references 24 major cities across global time zones, allowing the wearer to track dual zones simultaneously. The movement is entirely in-house and remains in production, serving as the caliber for the Lange Zeitzone watch.
