Not quite...
The Lemania version had the blocking lever for the chronograph (i.e. the brake) made of a single piece of plastic like say the Cal. 1861 uses, and the Omega version used a two part steel version like early 861's used.
Both used a plastic dial support.
Both also used a plastic gear in the 3/4 bridge (wheel train and barrel bridge).
