I have two Porsche design watches and without opening the cases, I am unsure what movements they hold.
The first, is an earlier one marked Orfina and the second has the PD logo in the same face location.
I believe the later PD version has the 7750 movement. Am I correct in assuming that the earlier versions had the Lemania 5100 movements or was it the other way around?
I am just a little confused in which order the movements were introduced.
