I have 2 33s, one in white with diamond bezela and black with diamond markers. I would ask your SA to measure both watches (33 AND 38)against each other and see if one is bigger then the other. I have an average wrist as well and had 2 links taken out (2 singles, one from each side where the watch clasp is). she should know what I am talking about when u tell her. I had 3 taken out originally, but it was snug. I like it a tiny bit loose. It should NOT turn all the way around on your wrist, like a bracelet. Good luck.
