Since this watch is small, can someone who has it tell me the size of their wrist?

My son has a small wrist. We took the watch to a mall jewelry store and they measured his wrist and took out three links to fit him. Charged us only $5..

can links be removed in this band?

Yes, links can be removed from this band.

How do you set the day of the week on this thing? I can't get it to advance unless I crank the Minute & hour hands 24 hours is there a faster way?

Yes. That is the only way to change the day of the week. You can wind it backwards if that is faster to get to the current day.

how to change the day of the week on timex watch?

The watch is basically a 24 hour watch. So every 24 hours the day of the week advances. Advance or decrease the minute hand. For every 24 hours the day of the week increases or decreases.
