At least in my mind, Patek has a history of shunning the norm and taking their own direction (like when they left the Geneve seal standard to create their own PP seal, which is completely without outside accountability, when you think about it, but nobody cared). Now this 30 m standard to unify 'all water-resistance' watches is almost overwhelming (though I hope we all have more important things to worry about). In their press release, they explain that by 30 m they REALLY mean 30 m. In other words, screw down crowns and swimming to what is a rather deep everyday level for most people while, for most other watchmakers, 30 m translates to: do not even THINK about swimming with it.
My problem is that they are now not distinguishing between some of their "sports" and "dress" models, AND, I offer a suggested solution a la Rolex. Why not use 30 m for dress watch water RESISTANCE such as Calatrava, etc. and use 30 m WATERPROOF (as does Rolex) for the sport watches with screw down crowns (Aquanaut, Nautilus, etc.) -- what do you think, AND does it matter at all? Here is their press release info on this in case you haven't seen:
"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 dayto-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."
No matter what, on a competitive level, it is sad to me to lose the 120M level that beat out most of the Rolex oyster-related line.
