Inside the Aquatimer chronograph

Hallo guys, good morning everyone. I am new here and I have a question for your attention.
I am very curious to see the inside of the Aquatimer chronograph (ref IW376803). I am particularly interested in seeing how the movement is mounted into the case, how the waterproofing system works, especially the part concerning the buttons of the chronograph function. Has someone some photos about it?
thanks a lot.
