A. Lange & Söhne · Zeitwerk
Jumping numerals across the dial instead of hands, driven by a constant-force remontoir that stores and releases the energy each jump needs — three discs switching simultaneously at the top of every hour takes far more force than a watch normally delivers, and doing it from the mainspring directly would wreck the rate. The bridge framing the numerals is the reason the layout reads as a watch rather than a display.
The 140.025 has been in production since 2009.
The A. Lange & Söhne 140.025 runs the L043.1, a manual movement.
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.
