Paperplanepilot,
I wore my citizen skyhawk watch into the assessment day, this particular watch has a whizz wheel on the outer bezel. They didn't check, or seem to care really. But to be honest it is not required, and they may get suspicious if you are playing with your watch during the testing.
As I said though you don't really need a whizz wheel for the assessment day questions.
All the best.
