Daytona Questions.

Apologies - I'm sure these have been asked before.

1) How do you know when the screw crowns/pushbuttons (all of them) are tightened enough..... Is it literally a question of tightening them as much as possible OR can they be over tightened?
2) When I tightened the main crown the rolex sign on the crown doesn't line up (I have OCD - sorry). I can slackened it off a tiny bit (so it is level) and it still feels pretty tight. Would this suffice if I swim with the Daytona on my wrist?
3) I like the sweeping hand to move but I don't want to overuse the the cosomograph facility - is there a risk of using it too much? Does anyone just leave the stop watch running 24/7?
4) Again, I like looking at my watch when all of the hands are in different positions, rather than being in the reset mode. Does anyone leave there hands in the 'stop' position while the stop watch has been running for a while - very much like you see the Daytona advertised?

Sorry for all of the questions. I'm like a boy with a new toy!
