Even if I totally understand your argument about the too small movement, but we can also argue that a lot of PP watches, and specially one among my favourite, have the same problem.
Take, for example, the 5102, the famous Celestial...
A 43 mm watch, if I'm not wrong, housing a small Cal 240...
I'm not disturbed with the Cal in the 5196P, because it has a solid case back, so nothing interesting to see, and it hides a bit the problem.
SZo I can focus on the beauty of the dial.
As for the Geophysic, it is a very important piece, for its History, and for its intrinseque qualities, indeed.
Best, my friend.
