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 right side of the dial features a pyramid-cut reading area that houses the hour and minute hands. It is surrounded by indexable inserts that form a tilted three-dimensional hour circle. Extended by a long strip in either red aluminum or anthracite, depending the version, perforated for a better view of the two biaxial tourbillons, it overlooks a power reserve indicator in roll form that is flush with a domed sapphire crystal.
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.
