Totally in house, launched in 1994 exactly because Zenith wanted to stop having to use ETA movements in its three handed watches. It won some awards at its debut, I believe. Its a very good piece of work, but remains relatively unklnown in the shadow of its famous older brother, El Primero. You'll note that in versions without central seconds, the small seconds hand is at the 9 o'clock position. Rumor has it that the Elite was created as a new platform for a whole range of movements, including chronographs, hence that location. In the end, though, Zenith decided El Primero was too valuable a property to mothball.
