Known for their luxury watches, Chopard combines their expertise with timepieces and their other specialty jewelry to create this interesting piece. In total, there are 874 diamonds of various size with the largest coming in at 15 carats. Adding that little extra wow factor is the mechanism which makes the largest three diamonds move apart, revealing the watch underneath.
