How to remove a watch link using at home tools.

Hello fellow homo sapiens! I needed to resize the watches I featured in my last haul and I asked my dad if we could take it to a watch shop. Instead, he said he knew how to fix it with just at home products and I thought, "why not?" And it worked. He showed me how the process works and I wanted to share with you all :D If you have any questions or concerns just leave them in the comments please :) I hope this helped and I really hope it wasn't all that complicated because I really tried to explain it as simple as I possibly can!
