Introduced in 2010, the Daymatic was the first automatic-winding Lange 1 and mirrors the standard model's dial: the power-reserve display is replaced by a retrograde day-of-week indicator. Caliber L021.1 uses a central rotor in place of the manual movements found elsewhere in the Lange 1 line, with a 50-hour reserve. The 39.5mm case is slightly larger than the 38.5mm standard Lange 1.

How do I check a A. Lange & Söhne 320.021 with Watch Safe?
Look up the watch's serial number in the Watch Safe registry to see whether a record exists or a theft flag is attached. A registry search identifies records for a specific serial; it does not authenticate the watch. Authentication is performed in person by an independent expert authenticator, and Watch Safe records and publishes the result.
