Ébauche, Incomplete watch movement.
Until about 1850, the ébauche consisted only of the bottom plate, bars, fusee and barrel. The old Genevese watchmakers called the ébauche le blanc, i. e. the blank.

In the early 19th century, the ébauche consisted of two plates with pillars and bars, the barrel, fusee, index, click and ratchet wheel, and a few assembling screws. These parts were all roughly filed and milled. The steel and brass parts were manufactured in special workshops. The ébauche was finished in the finishing shop (Comptoir d’établissage).

The modern ébauche is a jewelled or non jewelled watch movement without its regulating organs, mainspring, dial or hands.
