Three-quarter plate The three-quarter plate was introduced in Glashütte by Adolph Lange in 1864. Since then, it has been a typical feature of Lange watches. It accommodates the counter-bearings of the going train and enhances the stability of the movement.

Balance cock Small metal plate screwed to the visible side of the movement. It carries the balance wheel shaft bearing.
