Wearability might be subject to different angles.
From styling point of view, any of these watches maybe called “grandfather style” by one person and “goes with jeans” for another person. Which is a basic principle that applies to almost any luxury item. Take the 5320 as an example: in rose gold its more grandfather style, in white gold or pt more jeans style.
In my view: most of these can go either way whatever the owner likes
Collecting: from a collecting point of view: all of these can probably be daily wearers. Putting them in a safe so no scratches to bet on future values: the watches displayed are great but there have been too many produced to see 15-50% increase per annum
Admiring: thats something else again. If you buy the 5320 because you really admire it, then you want to keep it neat so probably wear it with special occasions only.
Its nice to read that all responses state that they bought a watch to wear it or admire it. No traders.
Personally I do the same (yet with another brand not PP): I’ve got daily wearers, and some pieces that I like so much to view that I don’t wears them often. But do admire them.
Finally, the one on the left, thats one of the few PP I really like
