Ebel, as a high-quality etablisseur, used very nice movements in its watches. Some are top and chronometer-grade ETAs, but many came from the deeper end of the pool. Famously, their Sport Classic Chronograph used the Zenith El Primero from 1982 to 1995, and Ebel was the first to do so after Zenith's Vermot had squirreled away the tooling during the Quartz Crisis. Ebel started using their own Lemania-based chronograph movement in 1995.
But they used some other famous movements, too. The Ebel calibre 330, for example, is a Girard-Perregaux 3300.
Another three-hand auto the used in the 90's is their calibre 060 and 080. This movement is a Lemania 8810. Lemania bought the movement tooling from Longines, where it was the L990. The 990/8810 uses serially connected dual mainsprings, where the auto winder powers only the first (which is the only one of the two to have a slip clutch to prevent over winding). The second spring is fixed on both ends like a hand-winder. This allows the second mainspring to move faster, which reduces power-train force. The result is very even power transmission and one of the thinnest autos ever made. It has been used by Breguet (expected given that Lemania is now Manufacture Breguet) and by other haute horlogerie companies (Vacheron, for example), often as a tractor for a chronograph complication.

This article describes the movement in detail and comes to very balanced conclusions about it (including why it should not be routinely hand-wound):

Ebel used this movement in several models, including this 1911 Senior, during the late 80's and 90's when they were riding high. The blue-dialed ST5 project watch made me want to expand my blue-dial repertoire, and this one is a uniquely Ebelian execution, with polished rhodium-plated hands and markers on the blue dial. And it's my first 1911 on a bracelet. The watch is in the Ebel 38mm case like my 1911 auto, though that measurement is from the smallest available diameter in this hexagonal watch. It is only 9mm thick.
More pics eventually.
