I haven't read the article and the link just goes to some advertising. So I'll wait until I see it. But who did they poll?
I can tell you that after visiting the PP factory as well as Vacheron ,Chopard, JLC and Dufours workshop that my order would be: Dufour, VC, Chopard, JLC and the PP. I watched the production, finishing etc. and I found PP disappointing just as I found Chopard a pleasant surprise with their staff highly committed to an excellent product. They are now using the Fleurier "seal" as a substitute for the Geneva one since they are outside the canton. I believe their criteria are just as stringant.
Unless the magazinelooked at things such as the number of repairs/model/year and other parameters I would think its pretty non-scientific and therefore not too meaningful except for advertising purposes.
Vacheron also had a highly dedicated staff and a lot more hand-finishing and some really skilled people. And I didn't even get to their enamel and engraving department in the Valle des Joux.
I'm sure it will please those who like to see their PP investment climb by leaps and bounds but it won't convince me to buy a PP at their inflated prices.
Just some thoughts.
