No price given. Needless to say, if you have to ask...
edit a look at their Wikipedia article, tens of millions seems more likely, if they even sell one.
I'd guess this model is somewhere in the $250k to $500k range.
That one was a pocket watch, but I doubt their wristwatch would be that much cheaper. Maybe I'm wrong.
edit the 250th anniversary watch was a wristwatch and went for a million at the time.
