Some help? 533, 531, 351

[Rushne]

Hey guys,
Its been a while since posting but the watch bug has bitten again. So tried to stay away from the Pam's. Checked a Rolex GMT Master II but it just doesn't suit me for some reason, I love seeing them on others but not me. AP 15400... strange looking on my wrist but might be because I have seen the 15300 in the wild and that is a better size/proportion.

I used to like the IWC Spitfire 3878 but after trying on a 1950's Luminor case... I really want one.

So I am torn between the 531 and the 533. The 351 is kind of a semi distant 3rd, mainly because I find the titanium too light for a PAM :)
The tobacco dial and gold hands are lovely though.

So the 531 has me at 24 hr traditional GMT, like my 297, however it is quite similar to my 297....

The 533 has that lovely 10 day reserve and I have really enjoyed the 7days the my IWC Portuguese gives me. I also would have loved to have the 270 back when I got my 297, but funds were a different situation back then.

I do not really plan on selling this watch as it is for my birthday present.

So what could you guys recommend?
Also, how do you find the polished cases? They are growing on me for adding a touch of "class" to the case, but I do love how brushed really shows off the shape of the case.

Anything outside of PAM I might be open to as well.... classic to commemorate a birthday (30) :)

Look forward to read some interesting input :)
