The tourbillon was invented in 1795 by Abraham-Louis Breguet and represents a milestone in watchmaking. This ingenious device aims to balance out all differences of position by mounting the rate determinative components – the balance, balance spring and escapement – in a delicate lightweight carriage which rotates on its own axis once every sixty seconds allowing many watches to attain chronometer-like accuracy.

The Breguet Ref. 5359 elegantly combines its namesake's ingenious invention, a tourbillon, with haute joaillerie. Housed in a sculpted 18k white gold case, further adorned with 134 baguette-cut diamonds (weighing approximately 10.37 carats) and 356 circular-cut diamonds (weighing approximately 0.50 carats) on the dial, this timepiece dazzles and exudes refinement. The delicate dance of the tourbillon is further admired through the sapphire crystal display back.
