As pointed out by Hewybaby, it is far easier to list all the companies that don't use ETA movements. First of all, I don't know of a single major Swiss or German company currently in existence that has throughout its entire history used only in-house calibres. Even Patek Philippe have used Lemania chronograph movements and Jaeger LeCoultre have also used Venus or Valjoux chronographs. JLC is probably the most autonomous company and supplies or has supplied many of the very renowned makers (Patek Philippe, Audemars Piguet, Vacheron Constantin, Cartier). I have seen old Lange watches with non-Lange movements, Rolex used Aegler movements until they took over that company (technically speaking only last year!), Zenith used ETA movements in the late seventies and eighties, Girard Perregaux have only recently because fully autonomous, etc. etc. Blancpain use no ETA movements, they use Frederic Piguet but have in the past used Adolf Schild movements which were swallowed up by the ETA.
If you want permanent ETA autonomy all throughout the company history, you have to go for some relatively small - and correspondingly expensive! - companies (Volker Vyskocyl, Dornblüth & Son, Roger Dubuis, etc.).

говорят зенит ставил ЕТА в конце 70тых начале 80тых

Zenith использовал в своих часах калибры производства ЕТА, с семидесятых по середину 199х годов. Эксклюзивный ЕТА 2832, 36 000 полук/час, семидесятые года:
а тут даже фото вашего калибра
и похоже вас ждет зенитовская ЕТА 2832 с частотой баланса в 36000 пк
а это интересно)
