No official corporate partnership or merger existed between LeCoultre & Cie and Eigeldinger.

Instead, their historical connection was a standard supplier client relationship typical of the early 20th-century Swiss watch industry:

– Movement Supply & Casing: Eigeldinger (including firms like Eigeldinger & Co. and

  A. Eigeldinger Fils) frequently functioned as an établisseur—a company that sourced

  movements from manufacturing watchmakers and paired them with custom cases.

– Collaborative Pieces: They collaborated on individual high-end pieces, such as

  luxury Art Deco pendant watches produced around 1925. These pieces utilized

  high grade movements manufactured by   LeCoultre & Cie. housed inside fine

  jewelry cases produced or retailed by Eigeldinger.

While LeCoultre & Cie. is most famously known for its major partnership and eventual merger with Edmond Jaeger to form Jaeger-LeCoultre, its relationship with Eigeldinger was strictly transaction-based for specific timepiece productions.
