Harry Winston – Histoire de Tourbillon 10 - Unique Collection 10th Anniversary Timepiece 2019
For the first time ever, Harry Winston uses four distinct tourbillons in a Histoire de Tourbillon creation. Arranged in perfectly symmetrical order, the four independent, adjacent cores rotate in 36 seconds, their high-precision steps unified by a series of three differentials. Together, they make Histoire de Tourbillon 10 a timepiece dedicated to superlative chronometry, with a unique design.

Having previously used tourbillons with single, double or triple axes, combined (or not) with single or double tourbillons or a carousel,
Harry Winston's latest creation makes a big impression with a new achievement in watchmaking. For the first time ever, a wristwatch produced as a series is equipped with four tourbillons. This achievement, which translates into an equally impressive design, represents a milestone in the story of the
Histoire de Tourbillon collection.
A milestone
Histoire de Tourbillon 10 marks the
10th anniversary of the
Harry Winston collection, dedicated to the reigning complication in contemporary fine watchmaking.

A decade of perseverance and innovation has pushed the boundaries of
what the tourbillon can do. This year, the collection culminates in two
timepieces --
10 of each -- and a special edition
Winstonium model,
limited to just one
unique piece.
A dream vehicle
A rectangular case was needed to realize the
Histoire de Tourbillon 10 complication. At 53.3 mm wide and 39.1 mm tall, the piece is as much a vessel as it is a watch.

The four tourbillons of the
HW4702 caliber, which has no less than
673
components, can be seen in the four corners of the case, housed in a
glass box of impressive proportions and supported by two transverse
bridges. Carved like three- dimensional wings, openworked and
sculptural, they round out the impression of symmetry that emerges from
Histoire de Tourbillon 10.
Distributed operation
The idea behind using multiple regulating mechanisms is to take advantage of the qualities of each one and harness their unique way of reacting to gravity, the effects of which the tourbillon is designed to offset. Thus, they do not mark the same time, but the same time must be given, so the operation of these mechanisms is unified by three differentials.

The first is connected to the two tourbillons on the left, while the
second is connected to those on the right side of the case. The third,
which is large and located in a central position, does the job of
averaging the two previous differentials and transmitting its
information to the juxtaposed hands.
Distributed power
The tourbillons are a major source of precision for
Histoire de Tourbillon 10, but they are not alone. Chronometry relies on other factors, including the quality of the power flow that feeds the regulating mechanisms. The closer this flow is to complete consistency, the smoother and more accurate the movement of the tourbillons is.

This phenomenon is made possible by two pairs of fast-winding barrels
that are overlaid, mounted successively, and then connected to the
tourbillons. As a result, the energy is not shared across the four
corners of the movement, but distributed as required.
Center stage
The
Histoire de Tourbillon 10 dial is a single component sapphire piece, with complex and perfectly symmetrical volumetry. Its central part is a hollow circle that hosts the 12 hour markers for the chapter ring. It extends upwards and downwards through a rectangular extension that carries the two large numbers 6 and 12.

The bezel of this exceptional timepiece also uses volume in a
distinctive way because it is chamfered and beveled, and features
greater elevation at 6 and 12 o'clock. At these two sensitive points,
the bezel is marked by two notches, which, together with the variation
in height, trace the three
Harry Winston arches. This reference to the
architecture of the entrance to the iconic Fifth Avenue Showroom is one
of the specific signatures of
Harry Winston timepieces.
In contrast
The surface coloring of the
HW4702 caliber rounds out the personality of the three versions of
Histoire de Tourbillon 10. The unique Winstonium piece can be recognized by its two large blue tourbillon bridges, a color borrowed from the gearwheel bridges inside the case, while the rest of the platinum is completely rhodium-plated. The white gold model features rhodium-plated tourbillon bridges and a dark gray platinum.

This shade is repeated on the back of the barrel bridge. Finally, the
version with the rose gold case inverts its colors in the barrel bridges
and features a rhodium-plated platinum. The strap of each
Histoire de
Tourbillon echoes the various models. The
Winstonium and white gold
versions are mounted on alligator leather with large scales and
topstitched with a
950 platinum thread. And, the pink gold version
launches a new bracelet color: black with copper highlights enhanced by
topstitching in rose gold thread. Elegant, sophisticated touches and a
profound attention to the tiniest details allow for a series of truly
unique timepieces.
