Cool winch mechanical watch

Just looking at the outside, this watch is so cool. Do you know how precise it is? It is the perfect masterpiece of a mechanical watch. Combining 1,352 parts in such a small space, there is not only that, but also a thin chain of 450 sections that acts as a drive linking the two dials of the watch, most of which are made of nickel and silver. It costs $275,000, or $400,000 if you want the deluxe version with white gold and diamonds.
