Help me choose the right one...

I'm going to buy a new watch and I'm pretty sure that it will be a mechanical Hamilton. The fact is that there are a lot of them which seems really similar, but I really don't know which is the best, if there's one (maybe it's a personal taste only, but there could be also technical aspects which I ignore!).
I really love the QNE (H76515533), cause the aviation design makes me fall in love.

but it's really out of budget for me.
So I'm searching for a "lower" model with a neat design and a medium-big sized bezel. The hand-winding ones meet my taste. I think that the field mechanical officer (H69619533) is really a beautiful piece:

but I've heard somewhere out there that the mechanical hand-winding system is more fragile than an automatic unit. Maybe someone of you experts can confirm this rumor or not.
Alternatively to this, I would choose automatic versions of king or field, which cost less but are less aviator-style watches. Suggestions about these two watches' series are also welcome.
As said, there are a lot of things depending on personal taste, but I really need some help based on experience or knowledge that I lack!

I apologize for the long digression and for the poor english, there's something to adjust there too :wink:
