For the seventh consecutive year, Harry Winston is unveiling an outstanding interpretation of contemporary Haute Horlogerie. Featuring two biaxial tourbillons, the Histoire de Tourbillon 7 takes another step forward in the world of high-end watchmaking and challenges current High Complications. Exceptionally creative, complex, and graphic, this timepiece showcases Harry Winston’s innovative expertise, while remaining faithful to Histoire de Tourbillon Collection, by maintaining the reliability of its complications and commitment to superlative watchmaking.
Harry Winston reveals its seventh edition of the most legendary complication: the tourbillon. After having explored its variations - biaxial, triaxial, double or coupled with a carrousel - Harry Winston surpasses all technical limits once again. In an incredible show, the Histoire de Tourbillon 7 features two biaxial tourbillons that dance with time.
The left side of the dial displays the harmonious movement of the two biaxial tourbillons. The first tourbillon cage moves into a second cage and both turn on a different axis. The two biaxial tourbillons move the escapements of the Histoire de Tourbillon 7.
This timepiece is profoundly asymmetrical, unpredictable and spectacular; an extreme paradox for a subject of extraordinary technical intensity, produced by the infinite sum of scientific calculations.
The Histoire de Tourbillon 7 is a striking example of brilliant mechanical complexity and technique. The tourbillon’s first cage completes its rotation in 45 seconds and houses a balance wheel that is tilted 30 degrees. The tourbillon and the balance wheel remain housed in the second cage, which has a different trajectory, as it lasts 75 seconds. The two cages nested one inside the other; assume an infinite variety of positions relative to gravity – the nemesis of timekeeping.
The Histoire de Tourbillon 7 is a sophisticated interpretation of a high complication movement, the result of exceptional attention to design. The case, made from white gold, has a 50 mm diameter and polished bezel. It features an opening in unique proportions to expertly showcase the dance of the biaxial tourbillons.
Every piece in the Histoire de Tourbillon Collection demands hundreds of hours of work in order to achieve perfection from every angle. The manual finishing of these tiny pieces is incredibly difficult and requires incomparable thoroughness. The bottom plate and bridges of this movement are made of titanium.
This material is necessarily strong but conveniently light weight and low maintenance. Notably, it is only 17 mm thick, a feat when considering the height required by each biaxial tourbillon. By choosing this material and minimizing its thickness, Harry Winston demonstrates its commitment to the wearer's experience.
The Histoire de Tourbillon 7 is an extraordinary timepiece and representation of true watchmaking. Its movement, showcasing first-class finishes, is among the most sophisticated that exist today. Its complexity demands extreme exclusivity. In fact, like its six predecessors, only 20 of these magnificent timepieces will be released: 10 pieces for the red version and 10 pieces for the anthracite version.
