Post some pics! We'd love to see them.
My thoughts on waterproofness is that you should get each watch checked individually. Just because Tom's PO is waterproof, doesn't mean Dick's or Harry's is too, even if they were built at the same factory, on the same day, by the same person. Take it to a local, non-AD watchsmith, and have him check it. Or dive right in and take your chances. Your choice.
Don't forget, these are replicas.
