The #MYSTERY_Numbers and the #Signature_Mechanism behind the A. Lange & Söhne 1815 “Homage to Walter Lange” Fourth-generation heir of F. A. Lange — Walter Lange (born July 29, 1924) — the man who had the courage to breathe new life into A. Lange & Söhne after the Berlin Wall fell. His hunger for perfection, devotion to handcraft, and love of outstanding engineering are distilled into the 1815 “Homage to Walter Lange.” Both the 297.* reference family and the L1924 calibre code his date and year of birth. Introduced in late 2017 as a tribute to his lifetime of contribution, the collection comprises three core versions, limited to 262 pieces in total: +/ 297.026 — White gold, silver dial (145 pieces) — marking the 145 years from the original founding (1845) to the revival (1990) +/ 297.032 — Pink/Rose gold, silver dial (90 pieces) — echoing 1990, the year of the revival +/ 297.021 — Yellow gold, silver dial (27 pieces) — representing 27 years of development from the revival to 2017 A unique piece in stainless steel with a black enamel dial was auctioned for charity in 2018. Equipped manual winding calibre L1924 with 253 components and 60h power reserve. Signature mechanism named “Seconde Morte” A central, independent dead-beat seconds hand that can start/stop via the 2 o’clock pusher, controlled by a column wheel — same as chronograph. Comparable “dead-beat seconds” from other brands exist, but they are typically less complex and lack this independent start/stop functionality that sets Lange apart. This is a heritage-grade piece for connoisseurs who cherish the A. Lange & Söhne story.
