The Graff Diamonds Hallucination watch costs $55 million

Blowing away the competition is also the only watch for women on the list — the gem-studded Graff Diamonds Hallucination from Graff Jewelry, a new name in the watch business that debuted at last year’s Baselworld watch show.
The bracelet has a tiny face and huge colored diamonds all set in platinum. Only one was made and as far as we know, it’s still up for sale if you're interested.
