The Zenith 400 'El Primero' was used as the base for the Rolex Calibre starting in 1988. It was heavily modified, including stepping down the high frequency balance from 36000 a/h to 28,800. All watch manufacturers who initially jumped on the high frequency bandwagon abandoned the 36000 a/h movts because of increased and rapid wear.
