Harry Winston Histoire de Tourbillon 5
Launched in 2009, the Histoire de Tourbillon series presents the tourbillon in spectacular new forms. The sage continues with Histoire de Tourbillon 5.
Building on the technical challenges introduced throughout the series – from Histoire de Tourbillon 1, which explores the movement and sculpture of the complication, to Histoire de Tourbillon 4, which seeks the next level of precision and performance – a powerful idea took shape: for the first time, the Histoire de Tourbillon 5 would fully reveal the exceptional mechanism behind the tourbillon.
To keep the focus firmly on the tri-axial tourbillon and its remarkable execution, watchmakers employed an unprecedented approach that could be called “watchmaking urbanism,” and led to the creation of a miniature mechanical metropolis. The movement and its various territories were reorganized on different levels like a mechanical landscape: a low-lying movement, bridges placed just below the surface, and the tri-axial towering over the scene from within its dome. The first stage, which involved open-working the movement in a ‘geographically’ minimalist style, served the sole purpose of whittling the mechanism down to its bare essentials. Next came the dimensional work – to ensure the mechanism remains prominently enthroned within the overarching sapphire crystal, the glass of the ‘porthole’ is fixed to a truncated base – a true tour de force in itself.
The spherical bridges beneath the Tourbillon are hollowed out to create passages beneath which the power reserve is cleverly fitted, all without any loss of function or coherence.
The case, which must form a single entity with the movement, is finely worked like a monobloc sculpture, defined by both sharp and declining angles, as well as two- or three-dimensional volumes.
The hour and minute functions are symmetrically isolated on the display – a decision that generated a number of mechanical and architectural challenges. The counters had to fit within a narrow perimeter, while still remaining perfectly readable and yet smaller than the Tourbillon – the star of the show.
The thickness of the movement required crucial choices in selection of the materials. Apart from the three-dimensional bridges, which are crafted in maillechort, all the other bridges are titanium and the disks are produced by galvanic growth. Weight calculations were an important factor throughout the design. To counter-balance the extreme lightness of the tourbillon carriages, a gold bridge was created to maintain the subtle balance of the carriages.
The timepiece comes in a limited edition of 20 pieces.
Harry Winston’s commitment to quality and fine craftsmanship, in keeping with the finest traditions of Haute Horlogerie, remains the unmistakable signature of a rare degree of legitimacy in the field of jewelry making and watchmaking creativity and ingenuity. A legitimacy that is well ahead of its time and directed towards a promising future without limitation or compromises.Find out more
