The Richard Lange Jumping Seconds reinterprets the concept of the scientific observation watch in a new way by pairing the quest for utmost precision with outstanding legibility. The balance is steadily driven by its one-second constant-force escapement.
An integrated jumping mechanism makes it possible to display the time in strict one-second intervals. With a diameter of 39.9 millimetres, this platinum timepiece with its prominent regulator dial is being launched in a limited edition of 100 pieces.
The Richard Lange Jumping Seconds is characterised by an intelligent combination of two mechanisms that functionally complement each other: A one-second constant-force escapement ensures ultimate precision. The jumping mechanism guarantees crisp legibility of the time; it advances the large seconds hand by exactly 60 steps per minute.
Thanks to the Zero-Reset mechanism, equipped with a multi-disc clutch, the watch can be synchronised quickly and comfortably: When the crown is pulled, the seconds hand jumps to the zero position. The Richard Lange Jumping Seconds is the latest model in a series introduced by A. Lange & Söhne in 2006, which has repeatedly leveraged innovative solutions to add new facets to the scientific observation watch.
The jumping seconds’ mechanism ranks among the classic complications in precision horology. Pocket watches featuring this technology were once used to determine sidereal or solar time as well as geographical longitude. But even in short-time measurements today, for instance when taking a pulse, it is convenient to be able to read the time in full seconds.
The jumping seconds’ mechanism has played a pivotal role in A. Lange & Söhne's history. After all, Ferdinand Adolph Lange developed a "one-second movement with a jumping hand" as early as 1867. Ten years later, the newly founded Imperial Patent Office granted one of its very first patents for his invention to the manufactory.
