Newer models also become thicker
The 51xx models are best by far IMO because of the sub-10mm thickness. The 52xx models then go over 10mm and now the 5330 is 12mm.
Then you see that the ladies' version is sub-9mm which makes me wonder why Patek intentionally increases case thickness on newer models (though understandably 5330 has the date complication).
