Apple Watch 1 - Swollen Battery

I know this is an old topic, but I really need advice on how to deal with it.

I have a SS Apple Watch 1 since January 2016. I have taken good care of it. Suddenly I found the screen detached without a fault of mine. A quick research revealed that it is a common swollen battery issue. My question is, knowing that my warranty is expired, will Apple fix it or replace it for me or that’s out of question?
