I prefer the J/F over the one you purchased. (I am not a Roman numeral fan at all.) But the diamond marker is definitely flashy and blingy and will get noticed on campus as very few university students wear Rolexes to school let alone a diamond one. I would sell the one you have and not buy a watch for a bit until you decide whether you are truly fine with wearing a flashy watch on campus. Indecisiveness gets expensive if you have to buy & sell to land on the right decision.
