Harry Winston Histoire de Tourbillon 4
This year marks the fourth year that the esteemed Harry Winston brand releases the Histoire de Tourbillon – this time the Histoire de Tourbillon 4 — one of the most complex mechanical timekeepers. The watch boasts a triple-axis tourbillon design to ensure that the tourbillon escapement is always in a different position and, hence, offering remarkable accuracy. The first cage (housing the oscillator and escapement) rotates once every 45 seconds; the intermediate cage rotates once every 75 seconds; and the outermost cage rotates once every 300 seconds. The movement of the watch consists of 345 parts and offers 50 hours of power reserve. Each Zalium cased watch takes more than 160 hours to build. Just 20 will be produced.
