The Richard Lange Jumping Seconds revives the historical “dead-beat seconds” complication once found in the world’s most accurate scientific observatory clocks. Rather than sweeping continuously, the seconds hand advances in precise one-second increments, making the passage of time exceptionally easy to read while emphasising the watch’s chronometric purpose. This distinctive display reflects Richard Lange’s dedication to measurement accuracy and demonstrates A. Lange & Söhne’s ability to reinterpret classical precision instruments for contemporary collectors.

Its exceptional manufacture calibre incorporates a sophisticated constant-force escapement that delivers uniform energy to the balance while simultaneously controlling the jumping seconds mechanism. Every movement is meticulously assembled, regulated and hand-finished in Glashütte, revealing untreated German silver bridges, mirror-polished steel parts, engraved decorative details and flawlessly executed finishing beneath the sapphire caseback. Technically ingenious and visually captivating, the Richard Lange Jumping Seconds ranks among the most important modern expressions of precision watchmaking.
