In recent years, the Histoire de Tourbillon collection has allowed the watchmakers over at Harry Winston (a brand usually associated with exquisite, diamond-studded jewelry) to really let their skill and creativity run wild with tourbillion and case designs – and the latest installment in the series is no exception.
The Histoire de Tourbillon 5 has a triple axis tourbillon which lies in a bulbous cage under the sapphire crystal bubble on the left side of the case. The triple axis part means that the tourbillion revolves on three axis points in a series of cages: the outermost rotates once each 300 seconds, the middle one, once every 75 seconds, while the innermost cage rotates once each 45 seconds.
At the heart of the timepiece there’s a manually wound movement called the caliber HW4303 consisting of 381 parts with 50 hours worth of power reserve and which beats at a frequency of 3 Hz (or 21,600 bph). The tourbillion itself is made of 143 parts, with much of the movement made from titanium. Hours and minutes are indicated on separate discs on the right of the dial, with a seconds counter near the tourbillion area and a small power reserve indicator above that.
As we’ve come to expect from Harry Winston models, the Histoire de Toubillon will be released as a very exclusive 20 piece collection.
