Can I buy a pre owned patek philippe watch without

[slice2020]

Hi, I'm looking to buy a pre owned patek watch. If I can be sure about authenticity of the watch, can I buy it without the certificate? because sometimes the former owner cannot provide it. Would it benefit me if I get one? (I don't think I'll use warranty since it's purchased more then 2 yrs) Thank you.
