The watch come with bracelet and rubber. The leather strap can be bought separately.
It has quick release system which makes the strap change in seconds.
This way your son can match the watch with any situation: rubber for sporty activities, bracelet for day to day, and leather for suits.
It is very thin at 9 mm, and with 41 mm diameter is perfect choice for your son's big and tall body.
Otherwise, from your choices i would pick The GO. The second is IWC but it is wear very large at 42 mm and thin bezel.
