In honor of company founder Walter Lange, who passed away in January 2017, A. Lange & Söhne is enriching the 1815 model family with an extraordinary complication. The 1815 “Homage to Walter Lange” has a stoppable jumping seconds hand that dates back to a 150-year-old invention conceived by Ferdinand Adolph Lange.

In this limited-edition version of the 1815, the small seconds hand at 6 o’clock maps the movement’s frequency of 21,600 semi-oscillations per hour by performing six small steps as it advances from marker to marker. However, the blued sweep seconds hand performs precise jumps from second to second. It can be allowed to run continuously or immobilized if needed. A pusher at 2 o’clock starts and stops it. This is useful for heart rate measurements, for instance.

With a 40.5mm case, the 1815 “Homage to Walter Lange” comes in three editions: 145 watches in white gold, 90 in rose gold and 27 in yellow gold. These uncommon numbers are derived from important milestones of the Lange family’s history. From 7 December 1845, when Ferdinand Adolph Lange originally established the company, exactly 145 years elapsed until 7 December 1990, the date on which Walter Lange registered Lange Uhren GmbH. Precisely 27 years will have passed between this date and 7 December 2017, the day on which the new model that pays tribute to Walter Lange is being unveiled.
