Got a Submariner today but have question.

[todesto]

Hi, all.

Got my second Rolex today and got some question and I got to here so that I can hopefully get an answer.

My first one was about 15 years ago and didn't know anything about it until today and got wondered as I was talking to sales rep from the shop today.

My wrist is thin so that I had to remove one link from the band to adjust the size but they had one side 7 and other side 4. They say it was to keep the face on top of the wrist and won't slide to the left on my left wrist. I've uploaded the pix. Is that true? I wasn't sure if I make it even, would that make that much difference?

Also my crown position.
My first Rolex crown position is at 12 o'clock so I thought every Rolex had that. However my Submariner crown is sitting at 9 o'clock, so I searched and some say 3 o'clock, so says random so wanted to get a solid answer.

What to you think?

Thank you in advance.
