Breguet for newbee...

After long saving and discussing with my wife I finally have the money and guts to buy a very nice watch.

So here we go again: I need your advice!!!

Besides the Jules Audemars 15058bc from AP:

And the Lange & S?hne 1815, I really like the Breguets Hora Mundi,

And a model like the Classique Retrograde 5207bb:

Do prefer smaller watches (my wrist), I don't care too much for chronographs.

Now, I've browsed the forum and there is something I want to avoid: some acquintance telling me later this type of watch I own is in fact an Omega or has many plastic parts in its interior (as you read sometimes in this forum). You catch my drift, right? You don't want that to happen with something you're very proud of and where you spent a lot of money on.

Any thoughts on the watches I mentioned? Any other Breguets I should consider (nothing is written in stone here)?

Thanks and regards from Belgium.
