Owning an A. Lange & Söhne timepiece is a decision in favour of the ultimate in watchmaking artistry. To this very day, Langes master watchmakers share Ferdinand A. Lange's ambition to craft “the world's finest watches”. Every single Lange watch is completed by hand, so each one is unique. This is exemplified especially by the freehand engraving of the balance cock: Every master engraver has an inimitable style that makes each piece one-of-a-kind. We cordially invite you to register your precious timepiece in our archives.
