These photos show what one of the Ebauche mechanisms from the "Better Watches" page looks like as it is disassembled. You can tell that this is an Ebauche because it has the letters "ETA" under the balance wheel. There are many Ebauche companies, and ETA produced huge quantities of watches. Select This Link if you would like to see a webpage with the names for the different watch parts, (webpage will open in a new window).
