New Submariner with questions pertaining to functionality and security. Please help!!

[AAWO9]

Hello everyone.

I recently bought a Rolex Submariner and decided to join this superb forum for some updates and questions.

Bezel----
1.) The bezel seems fine, however I read somewhere that a real Rolex Submariner will turn 120 clicks per cycle or about 30 per quarter. I got 18-19?

2.) Additionally, when I gently press the bezel in the 12 and 6'o-clock position the bezel moves slightly. Is this normal?

Winding----
3.) Can you overwind your Submariner?

4.) How do you know if you've winding enough?

5.) How long should it function on a full wind until it goes to "sleep" mode?

6.) What's the best way for me to wake up from "sleep" mode, just wear it or manually update the time and date?

Authenticity----
7.) Since this watch is so popular it seems to attract a lot of unwanted copycats and fake imitations. How can one be certain he/she is getting the real deal?

-Crown lasered in on glass above the six'o-clock (hard to see)
-"rolex" is engraved on the inside ring along with code and crown on the 12'o-clock position

What other features can I look into without opening the actual watch to check authenticity?

I know that's a lot but if you can just answer one you're truly helping me out here. If you can answer a few please just quote me or use the numbers to help me out. Cheers and thanks in advance. I look forward to acquiring knowledge from all you Rolex Owners!
