My timepiece says it's water resistant to 330 feet (100 meters). Why is it Ok for swimming and not diving?

A. Most models are rated to withstand water pressure up to 330 feet or 100 meters (there are some exceptions). In contrast to the term "waterproof," water resistance is not a permanent condition; it must be maintained.

The crown must be fully recessed and parts such as the crystal, case, and push buttons must remain intact for the timepiece to stay water-resistant. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
