A historically inspired timepiece with dead beat seconds from A. Lange & Söhne to honor its deceased company founder Walter Lange, who passed away in January 2017. The new A. Lange & Söhne 1815 ‘Homage to Walter Lange’ is the first  1815 model fitted with this extraordinary complication. This new watch equipped with  a  jumping seconds hand that dates back to a 150-year-old invention conceived by Ferdinand Adolph Lange is as classic as it gets.
