i've never owned a gold watch(but have bought a couple of gold coins before) so i'm curious. do they come with assay certs and some sort of cert that say how much gold is present(like, in ounces)?

and also, isn't it a little bit impractical in reality as well? gold being a soft metal will wear out if you wear it? then there could be less gold than what it says on the cert?
