Newbie Size Question

[Rashid.bk]

I'm starting to like Panerai. The simple and symmetrical dials are really luring me in. The only problem is I don't like watches larger than 44mm.
There are a few styles I like but it boils down to the 1950's style cases, with hours minutes and seconds display. I like plexiglass but don't mind sapphire.
I like the 422 but it's 47mm.
I tried looking at the Pam website but it's a bit confusing so thanks in advance for any help.
My question is, are there any 42-44mm Pams that fit the looks of the 422 or is 47mm a standard Pam size in the 1950s case. Excuse my ignorance if I have described something wrong.
