A. LANGE & SÖHNE

1815 “Homage to Walter Lange”


This new jumping seconds watch from A. Lange & Söhne has been historically inspired. It is a timepiece that has been especially devised to honour company founder Walter Lange, who passed away in January 2017. A. Lange &Söhne looked to the 1815 model family to host the complex complication that makes up this watch. It is here in fact, that the historical inspiration can be seen.

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. The jumping seconds, as we all know, allows the exact measurement of the smallest unit of time: the “jumping seconds”. This is what has been mastered in the watch.

The small seconds hand in the subsidiary dial at 6 o’clock maps the 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 immobilised if needed. A pusher at 2 o’clock starts and stops it. This is useful for heart rate measurements, for instance.
