If I replace the screen, will I lose apple pay if I haven't fully set

I got my apple watch 3 as a gift last year. I put in my credit card on apple pay, but have not verified the credit card yet, still needs to be verified. I don’t want to pay $150+ to get it repaired, but I can repair it myself. However , I don’t want to lose apple pay on my apple watch.
