Like the original Deepsea (circa 1960), the new Deepsea Challenger was designed for marketing purposes only. It was never intended to be worn, at least not without a (gold) diving bell around your head.
On the other hand, if you appreciate the technology that went into it, then an accurate rep might be an interesting piece to have in your collection. I certainly would never want to be seen in public wearing 1, but, then, I feel the same about the current Deepsea, which has become a relatively popular model.
