Jeg tror egentlig ikke PP har gjort noen endringer på klokkene, men at de innfører sin egen konservative standard for hvilke dyp de kan faktisk kan brukes på.
Fra pressemeldingen:
Unified criteria for water-resistance
To ensure the homogeneity and clarity of the information provided to clients, Patek Philippe has decided to introduce a new unified standard of water-resistance set at 30 meters for all watches certified as waterresistant –having been tested in air and underwater by immersion at an overpressure of 3 bars (corresponding to a depth of 30 m). This measure makes it possible to guarantee the same performance level across all the models concerned and to provide perfectly comprehensible information as to the day-to-day activities in which clients can engage while wearing their watch: washing their hands, showering, bathing, swimming and other aquatic activities, including diving to a depth of 30 m – which corresponds in large measure to actual utilization.
Dette er jo et område med mye uklarhet fra før. De fleste av oss har jo blitt fortalt 30 m/3 bar ikke er nok til bading - Oris mener f.eks det:

Mens i følge ISO 22810 så skal en klokke med 3 bar WR takle svømming og snorkling, her fra Longines:
