In contrast to the caliber L101.1 above, this movement is limited to the essential functions of a rattrapante chronograph, i.e. it does not display date and power reserve.

This movement is used in the models 1815 Rattrapante and 1815 Rattrapante Honeygold „Homage to F. A. Lange“.


  • Precision adjustment: cam-poised balance
  • The movement decoration is reminiscent of the historical pocket watches in 1A quality:
    • Raised nickel silver frame parts are finished with grained surfaces.
    • Moving parts of the rattrapante chronograph such as levers, springs and detents are decorated with a line cut on the top, while the chamfers are polished.
    • The hand engravings on the cocks and bridges as well as the engraved inscription are black rhodium plated.

  • 21.600 A/h
