A big congrats on acquiring a beautiful timepiece. I am a big fan of the 5496 and was fairly close some time ago in going for the brown dial P. What held me back was primarily my attachment to my 5960p as I could not justify having both in my box.... yes different kind of watches but too close for me...
Now as to your reasoning in regard to Patek makes sense. No small commitments to purchase and important it ticks all boxes. However the most relevant box to tick that many overlook is the self assessment part. If you really love it there is little wrong in going for it... so gain, huge congrats!! Hope much enjoyment will be experienced with this one!
Looks superb on the light strap!
