Problematic Fossil Watch

I bought a Fossil Watch from Watch Republic as a for me from me birthday present. I wore it a couple of times when the strap broke. Watch Republic did sort it out for me, but I was without my new watch for a couple of weeks. Now the "stop watch" buttons stopped working. This is obviously a faulty watch. Hoping I can be refunded for the watch so I can buy something else as I no longer have any trust in Fossil watches.
