I can confirm that the Lange top management team really cares for their customers. I myself encountered the issue with my Lange 1815 chrono. There was some flaw on the dial that could not be repair. It is due to the manufacturing process.
Lange decided to replace me with the new watch, new box, and all the documents.
Truly amazing how they deal with their customers. I really appreciate Lange. This is how you built customers loyalty. Thumbs up A Lange & Söhne.
