Dear Experts--How often should my Rolex be pressure tested?

[Gab27]

I've read different things on different forums about this. Obviously, I recognize that it is a lot more expensive to overhaul a watch that suffers water damage than it is to replace gaskets. I also assume that gaskets/gasket lubricants have improved substantially since some of the things I've read on forums dating 10+ years back.

I'm going to be doing quite a lot of swimming and some diving this summer (under 60 feet) and I plan to wear my watch while doing this now and going forward given that is what it is made for. It's about a 2.5 year old 114060 and I am the second owner. Presumably, it might not need movement service for another 5-8 years, but I know that gaskets can degrade in that time. Usage will be fresh, brackish, and salt.

With regular aquatic usage, how often should my watch be pressure tested?
