... as I think that a watch of this caliber has to be a piece of jewellery.
The Nautilus is arguably an icon in the PP range, but it lacks the preciousness character too much.
Not to say that it looks mundane but a bit too understated.
The coloured gold PPs would be my choice as you have put them also on your list.
That particular Lange that you have chosen does not look like a wrist watch at all to me and more like a yacht chronometer.
It is also too big.
The 5146 YG with slate grey dial would be my choice, or the 5124 J, 5119 J or R, 5296 R ... you know them.
Also: if it is not a minute reapeater ( as not waterproof and just dustproof ) you can wear any PP daily.
One nearly forgets to wear a watch if you chose a thin model and that is very much nicer than a big chunk on the wrist.
What is VERY important is that one should know that tings can go wrong and should be therefore also be prepared to pay if so.
Therefore the price for a PP is even higher than the retail price only.
BUT: a PP was, is and will be the epitome of elegance and beauty ...
