I know I know, they changed the rating for all their watches to 30m recently but my take is that this was done in an effort to have all Pateks have the same water resistance. The new 30m are 100% for real and you can take em down to 30m no problem. Also I still believe that the 5980 and 5968 can do a lot more as they had been rated at 120m for many, many years. .
