The thing is (about WR) that the Tissot and IWC are resp. 28% and 34% thicker than a 5712 (hence more room for thicker gaskets, etc...), which is a rather huge difference.
About the PR, it would be interesting to know what are the accuracy of these calibers. Patek's are below COSC required limits.
What I mean is that it depends on what the owner is interested in as a watch usually can't have all at the same time (thinness, PR, WR, Shock resistance, reliability, etc...).
