If you don’t want to use Python you can use Modell Builder. Model Builder has several iterator tools. Use [Iterate Feature Selection][1] to iterate over features in a feature class (your watersheds). Then use [Clip Tool][2]. You have to run this modell 10 times (one for each of your 10 raster). Here are some [examples of using serveal iterate tools][4].
