Right- so racing to Wiki which isnt terribly helpful- there was an original series of "Daytona" chronographs between the 60's and the late 80s- and these had the Valjoux cal 72- as had previous Rolex chronographs. But the modern Daytona series ( from the middle 90s)- these were originally released with the Zenith, never had the Valjoux. Is that right?
