This is what works for me, to each his/her own.
Shoes, I go with cheap white sneakers which I replace every semester. I tried expensive leather shoes that killed my feet, so they now gather dust in my closet. You may be required to have smooth tops, as in no strings, in case anything gets on them.
Socks, I choose to spend some money here, nice, soft, thick, comfortable.
watch, CHEAP CHEAP CHEAP, it has to have a second hand, I like a metal band not leather so that I can clean it well, save your $ for a nice watch to wear to class or go out in, not for the hospital, nobody, and I mean nobody is going to care about how fancy your watch is at the hospital (well,...they shouldn't anyway) Your drug book, now that's a useful item to refer to at clinical.
I also added a watch that clips on to my 'scope after I forgot my watch one day.
