ipod running chip

Can you guys recommend a running watch?
Im looking for a running watch for my birthday. I am currently attempting to qualify for Boston Marathon on May 30th at the Ottawa Canada marathon. I’m turning 19 years old and my dad wants me to find him a watch to buy me. I would say maximum $200 dollars.
I run about 6 days a week and I cover long distances, but I haven’t ever had anything to record my time while I run. Does anybody have any good, or bad experiences they would like to educate me with? I also do interval training if that helps. Having a timer I can occasionally check on it is key.
I have already tried that Nike running chip that you put in your shoe and is wirelessly connected to your ipod. I didn’t really like it.
I’m looking for something a little bit sporty that I can wear day to day also.
Thanks very much
Digital watch please n thanks
