Besides showing the time, this watch also accurately displays the movement of 6 planets in our solar system as they orbit the Sun.
Each of those 6 planets are represented by a precious or semiprecious stone selected to represent that planet’s color.
It costs $250,000 USD. The watch took 396 pieces and 3 whole years of work to complete so, along with the precious stones dotting its surface, the price tag comes as no surprise.
The movement of each planet is true to its genuine length of orbit: it will take Saturn over 29 years to make a complete circuit of the dial, while Jupiter will take almost 12 years, Mars 687 days, Earth 365 days, Venus 224 days and Mercury 88 days.
