This or That?

So I have $80.00 worth of Amazon gift cards that I've had since christmas...I finally went on Amazon today to look at stuff. These are two different things that I have wanted for awhile now. The shoes are $47.00 and the watch is $69.95. Basically I don't know which one I should get. If I get the shoes then I have a lil bit more money to spend on something else to. If I get the watch then it'll probably be about all I can get. So what do you think I should do? Or do you have any other ideas of what I could spend this money on?
