A. Lange & Söhne Richard Lange Jumping Seconds

Partially verified

The A. Lange & Söhne Richard Lange Jumping Seconds, reference 252.056, is a wristwatch featuring a regulator-style dial configuration. The 39.9mm case is constructed from 18K white gold and contains a solid pink-gold dial with three overlapping circular displays for hours, minutes, and seconds. The seconds display occupies the largest area and advances in one-second increments via a constant-force mechanism. A triangular aperture functions as a power-reserve indicator, changing to red when approximately ten hours of power remain. The manually wound Calibre L094.1 movement incorporates a zero-reset function that stops the balance and resets the seconds hand to zero when the crown is pulled. The watch is presented on a brown leather strap with a signed 18K white-gold pin buckle. It includes the original box and accompanying documentation.

Object description

Case and Dial

The watch is housed in an 18K white-gold case measuring 39.9mm in diameter. The dial, crafted from solid pink gold, employs a regulator-style layout where the time is read through three distinct overlapping displays for hours, minutes, and seconds.

A specific feature of this dial is the jumping seconds display, which moves in distinct one-second increments rather than a sweeping motion. A triangular aperture situated at the intersection of the dial displays provides a visual warning when the power reserve is low, specifically turning red when approximately ten hours of energy remain.

Evidence for this section
  • “39.9mm 18K white-gold case with a solid pink-gold dial arranged in a distinctive regulator-style configuration”
  • “its hand advances in exact one-second increments. This “deadbeat” or jumping-seconds indication isn't simply a visual trick”
  • “A small triangular aperture at the intersection of the three displays serves as a low-power warning, turning red when approximately ten hours of reserve remain.”

Movement and Functionality

The watch is powered by the manually wound Calibre L094.1, a movement designed to support the jumping-seconds complication. It incorporates a constant-force mechanism intended to provide consistent energy to the escapement as the mainspring loses tension.

The movement includes a zero-reset mechanism. When the crown is withdrawn, the balance wheel stops and the seconds hand automatically resets to the zero position. This feature allows for the synchronization of the watch against an external reference time. The movement provides a total power reserve of approximately 42 hours.

Evidence for this section
  • “Inside is the manually wound Calibre L094.1, a movement developed around this unusual chronometric architecture”
  • “Beyond its constant-force mechanism, Lange incorporated a clever zero-reset function: pull the crown and the balance stops while the seconds hand instantly returns to zero”
  • “The movement offers approximately 42 hours of power reserve.”

Accessories and Presentation

This specific example is equipped with a brown leather strap, which is secured by an 18K white-gold pin buckle signed by the manufacturer.

The watch is offered as a complete set, including the original inner and outer presentation boxes, as well as the factory-issued pamphlets and paperwork.

Evidence for this section
  • “This example is fitted to a brown leather strap with a signed 18K white-gold pin buckle”
  • “accompanied by an especially desirable assortment of factory accessories, including its inner and outer boxes, papers, and pamphlets.”

Open research questions

  • Does the movement contain any unique identifiers or hallmarks visible beyond the caseback?
  • Is the jumping seconds mechanism permanently enabled or can it be disengaged?
