I didn't want to hurt you in my answer.
Remember that English is not my native language, too.
I just wanted to share with you what is the most interesting with Panerai: The discover.
A bit of homework is necessary, and part of the pleasure.
The problem with Panerai is that this brand is a bit like a Labyrinth.
What does represent a Panerai watch?
A big, strong watch, so, in my mind 44 mm are a minimum.
With a minimalist design, too.
So, as a first Panerai, I would consider a Base ( Logo Pam 000, or 112 ), or a Luminor Marina ( Pam 005 or 111 ), or a Radiomir ( 232, 190, 249 ).
44, 45 or 47mm.
The problem with the 40 mm pannies is that you're pleased a couple of weeks with, and after, yuo look toward 44 mm watches, and you begin to think about selling it to go on a bigger one.
This is a trap I wanted to warn you about.
But ifb you're happy with the 48 or 49 and if it is really the watch you want, go for it, the most important is that you're happy with.
No nerves nor offense, but just the experience of some guys who are ( or were ) into Panerai for some 10 years...
So nothing beats the tests you can do, put the maximum of pannies on your wrist, compare them, take your time, and you'll know.
Best, my friend.
