I think the Harry Winston Opus 12 might be the most expensive watch we have ever featured on Brainspin. This watch rings in at just about $280k and is limited to 120pcs. I put my order in for 2 of them so its now limited to 118pcs. But seriously, the details on this thing are crazy, the hour and 1/12th of an hour (five-minutes) display via a rotating, double-hand system. Every Change of the hour is animated by the hour hands. It has a power reserve indicator and many other things I feel like i would have to see to understand..hit the link for all the details.
