Hi Thomas,
I still think that PP is the only brand that already from the 40's have consistently made series of complicated wristwatches. Of course as years went by more and more brand started making complicated watches in series, nowadays every brand seems to make (sell) them. AP deserves credits for their flat automatic perpetual from the end of the 70's and their tourbillons. But if you look at what PP has produced in lets say the 40's 50's and 60's (some of those series were produced untill the 80's) I don't think there is a brand that can match that:
The worldtime watches (f.e. the 1415 HU)
The split second chronographs (f.e. the 1436)
The perpetuals (f.e. the 1526, 2497 and 3448)
The perpetual calendar chronographs (f.e. the 1518 and 2499)
Of course those series where all small, a few hunderd pieces at the maximum.
Besides these references there are also the more rarer pieces, for example the 1563 split second chrongraph or the 2571 split second perpetuals. Regarding chronographs and minute repeaters I'm not quite sure, AP and VC may have produced them in the same amount or maybe even more than PP.
It's interesting to note that the watches mentioned above are the watches that fetch the highest prices at auctions. So again an innocent bystander at auctions or not, I still think it is a great achievement of PP that they produced all these watches.
Regards,
Joram
