$10000 is unlikely
Nevertheless, a high price serves a purpose. A gold designer watch declares "if you mate with me, there will be money for some fun, and for the child". Any other functionality is incidental.
The latest news is that Apple's 18 carat gold is not an alloy with other metals, but a composite with lightweight ceramic material. Still 18/24ths gold by weight, but only about 7/24ths by volume. See how Apple gives you less, but still gives you what you want?
The main purpose of the watch is to handle 95% of interactions without taking the iPhone out of your pocket/bag, and to register notifications instantly instead of next time you happen to look at your phone. It's the iPhone giving us back our lives at last.
