Waterproof questions and Sapphire crystal questions

[springolators]

I have read a bit on this forum, and noticed that a lot of people are not so into sapphire crystals on their watches.

Are there any good points to these? Do they possibly last longer? Show less scratches? Am I mistaken or do all new rolex come with sapphire crystals now?


I would also like to know more about how rolex stay waterproof? Some people on the forum say that if I get an after market bezel it will no longer be waterproof? Does this mean that if you remove the bezel from any rolex it will no longer be waterproof?

I do not plan to go swimming with the watch, but what if I get caught in the rain?
