The "blow up" watches nowadays are meant to cater for current market needs. Unfortunately, even PP joins the group to produce bigger watch with original small movement. I personally don't like such idea.
I am surprised that you find 34mm is a perfect size despite your height. Do you have big wrist? I find it right on my wrist (7 1/2") but my height is only 168cm.
PP5026 platinum is the perfect piece that I can safely say " I will keep it for my son".
I wish you all the best of luck to collect the rest of the metal to complete your collection of PP5026.
