History
One of the oldest continuously operating Geneva houses, the firm worked within the établissage system, buying ébauches and finishing to a high standard, and produced complicated and engraved pocket watches through the nineteenth century.
Major innovations
- Early adoption of interchangeable-part methods by Georges-Auguste Leschot in Geneva
Known markings
- Maltese cross mark in later periods
- Geneva hallmark on selected watches
Serial numbers
Company archives are used for confirmation; the 1755 founding date is the firm's traditional claim rather than an independently reconstructed record.
Collecting significance
Original dials, cases and archive support are the principal research questions.
