Hi JC,
The first perpetual wasn't the 1526, they made a few unique ones before that without reference. The first Split-sec perpetual was the ref. 2571. 3 were sold in the fifties I believe. Here's a picture from the PP museum site
The first repeater might be the one below (pic from antiquorum). It is the first perpetual minute repeater wristwatch for sure, from 1939.
Regards,
Joram
