Exchange Apple Watch after 14 day policy

I bought my watch 19 days ago so it's 5 days over the policy. But it froze after the return policy date and I was wondering if they will let me exchange it for a new one. Anyone have answers or experience exchanging a new Apple product after the 14 day period. My watch had a problem after and it's not a lot after the 14 day window so I was wondering if they will still exchange it for me.
