thanks for all the input guys! i really appreciate it.
I decided to go with a used SS navitimer for now. It's in minty fresh condition and will introduce him to watches 40mm and up.
If he likes it from there, then i'm sure i can move him towards the SO anytime
or... he ends up getting one on his own
btw... his wife helped me out and we found his wrists to be about the same size as mine
6... 6.25 inches
OH boy! can't wait when he gets it
